Getting 2nd TIO of the PCI6602 to perform buffered event counting via register-level programming

I got the first PCI6602 TIO to perform buffer event counting using interrupt. However, I could not get the second TIO working. I think I have initialized the proper registers in order to work with the second TIO, i.e.
1. Addressing all registers of the second TIO at 0x800 offset.
2. Binding the clock to counter 4-7 (set 0x00200000 to the Clock Configuration register). I am using the internal Timebase_3 clock which is 80MHz.
3. Tried setting 0x8000 to the Global Interrupt Control register at both its offset location (with 0 offset) and with 0x800 offset (2nd TIO offset location).
Am I missing something here? I got no interrupts from the PCI bus and I got 0xff
ff when I tried to read the Status register.

Al,
I have been experimenting with the 6602, but I have not been able to see any of the interrupts generated by the counters. I have tried both TC mode and an external signal on a single GATE (G0). The Gi_Status_Register indicates that the interrupts are occuring (appropriately for each mode), but I can't see them on the bus (my interrupt handler is never invoked; cat /proc/interrupts shows 0 interrupts).
Could you pass along any tips on how you did it?
Thanks!

Buffered event counting. Why can't I explicitly sequence generating the Sample Clock Pulse and reading the counters?

At irregular occasions I need to grab counts from several counters, and buffering the counts must be done simultaneously for all counters. I'm modeling my approach after zone.ni.com/devzone/cda/tut/p/id/5404 which someone kindly pointed out in an earlier thread. However, that example only uses one counter, and you can't test the synchronization with only one counter, so I am using two counters configured the same way, and they're wired to a single benchtop signal generator (for example at 300 kHz).
What I want to do, I can test in a loop with a somewhat random wait in it. I want to drive a hardware digital output line high for a few ms and then low again. The hardware line is physically connected to terminals for my timing vi's Sample Clock Source and so will cause them to buffer their counts for later reading. After I pulse this line, when I know new good buffered counts await me, I want to read both my counters. If their bufferings are simultaneous, then each counter will have counted the same number of additional counts since the last loop iteration, which I can check by subtracting the last value sitting in a shift register and then subtracting the two "additional counts" values and displaying this difference as "Diff". It should always be 0, or occasionally +1 followed immediately by -1, or else the reverse, because buffering and a count could happen practically at the same moment.
When I do this using a flat sequence to control the relative timing of these steps, so the read happens after the pulse, the counters often time out and everything dies. The lengths of time before, during, and after the pulse, and the timeout value for the read vi, and the size of the buffer and various other things, don't seem to change this, even if I make things so long I could do the counting myself holding a clipboard as my buffer. I've attached AfterPulse.vi to illustrate this. If I get 3 or 10 or so iterations before it dies, I observe Diff = 0; at least that much is good.
When I use two flat sequences running in parallel inside my test loop, one to control the pulse timing, and the other to read the counters and do things with their results, it seems to work. In fact, Diff is always 0 or very occasionally the +/- 1 sequence. But in this case there is nothing controlling the relative timing such that the counters only get read after the pulse fires, though the results seem to show that this is true. I think the reads should be indeterminate with respect to the pulses, which would be unreliable. I don't know why it's working and can't expect it to work in other environments, can I? Moreover, if I set some of the pulse timing numbers to 1 or 2 or 5 ms, timeouts start happening again, too. So I think I have a workaround that I don't understand, shouldn't work, and shouldn't be trusted. See SeparateSequence.vi for this one.
I also tried other versions of the well-defined, single sequence vi, moving the counter reads to different sequence frames so that they occur with the Sample Clock Source's rising edge, or while it is high, or with the falling edge, and they also often time out. I'll post these if anyone likes but can't post now due to the attachment limit.
Here's an odd, unexpected observation: I have to sequence the reads of the counters to occur before I use the results I read, or else many of the cycles of this combine a new count from one counter with the one-back count from the other counter, and Diff takes on values like the number of counts in a loop. I though the dataflow principle would dictate that current values would get used, but apparently not so. Sequencing the calculations to happen after the reads fixes this. Any idea why?
So, why am I not succeeding in taking proper control of the sequence of these events?
Thanks!!!

Kevin, thanks for all the work.
>Have you run with the little execution highlighting lightbulb on? -Yes. In versions of this where there is no enforced timing between the counter and the digital line, and there's a delay inserted before the digital line, it works. There are nearly simultaneous starts on two tracks. Execution proceeds directly along the task wire to the counter. Meanwhile, the execution along the task wire to the digital high gets delayed. Then, when the digital high fires, the counter completes its task, and execution proceeds downstream from the counter. Note, I do have to set the timeout on the counter longer, because the vi runs so slowly when it's painting its progress along the wires. If there is any timing relationship enforced between the counter and the digital transition, it doesn't work. It appears to me that to read a counter, you have to ask it for a result, then drive the line high, and then receive the result, and execution inside the counter has to be ongoing during the rising line edge.
>from what I remember, there isn't much to it. There really aren't many candidate places for trouble. A pulse is generated with DIO, then a single sample is read from each counter. -Yup, you got it. This should be trivial.
>A timeout means either that the pulse isn't generated or that the counter tasks don't receive it. - Or it could mean that the counter task must be in the middle of executing when the rising edge of the pulse arrives. Certainly the highlighted execution indicates that. Making a broken vi run by cutting the error wires that sequence the counter read relative to the pulse also seems to support that.
>Have you verified that the digital pulse happens using a scope? -Verified in some versions by running another loop watching a digital input, and lighting an indicator, or recording how many times the line goes high, etc. Also, in your vi, with highlighting, if I delete the error wire from the last digital output to the first counter to allow parallel execution, I see the counter execution start before the rising edge, and complete when the line high vi executes. Also, if I use separate loops to drive the line high and to read the counter, it works (see TwoLoops.vi or see the screenshot of the block diagram attached below so you don't need a LV box). I could go sign out a scope, but think it's obvious the line is pulsing given that all these things work.
>Wait! I think that's it! If I recall correctly, you're generating the digital pulse on port0/line0... On a 6259, the lines of port 0 are only for correlated DIO and do not map to PFI. -But I'm not using internal connections, I actually physically wired P0L1 (pin 66) to PFI0 (pin 73). It was port0/line1, by the way. And when running some of these vi's, I also physically jumper this connection to port0/line2 as an analog input to watch it. And, again, the pulse does cause the counter to operate, so it clearly connects - it just doesn't operate the way I think it is described operating.
For what it's worth, there's another mystery. Some of the docs seem to say that the pulse has to be applied to the counter gate terminal, rather than to the line associated with the sample clock source on the timing vi. I have tried combinations of counter gate and or sample clock source and concluded it seems like the sample clock source is the terminal that matters, and it's what I'm using lately, but for example the document I cited, "Buffered Event Counting", from last September, says "It uses both the source and gate of a counter for its operation. The active edges on the gate of a counter is used to latch the current count register value in a hardware register which is then transferred via Direct Memory Access...". I may go a round of trying those combinations with the latest vi's we've discussed.

Doing Buffered Event count by using Count Buffered Edges.vi, what is the max buffer size allowed?

I'm currently using Count Buffered Edges.vi to do Buffered Event count with the following settings,
Source : Internal timebase, 100Khz, 10usec for each count
gate : use the function generator to send in a 50Hz signal(for testing purpose only). Period of 0.02sec
the max internal buffer size that i can allocate is only about 100~300. Whenever i change both the internal buffer size and counts to read to a higher value, this vi don't seem to function well. I need to have a buffer size of at least 2000.
1. is it possible to have a buffer size of 2000? what is the problem causing the wrong counter value?
2. also note that the size of max internal buffer varies w
ith the frequency of signal sent to the gate, why is this so? eg: buffer size get smaller as frequency decrease.
3. i'll get funny response and counter value when both the internal buffer size and counts to read are not set to the same. Why is this so? is it a must to set both value the same?
thks and best regards
lyn

Hi,
I have tried the same example, and used a 100Hz signal on the gate. I increased the buffer size to 2000 and I did not get any errors. The buffer size does not get smaller when increasing the frequency of the gate signal; simply, the number of counts gets smaller when the gate frequency becomes larger. The buffer size must be able to contain the number of counts you want to read, otherwise, the VI might not function correctly.

Where is the SCXI-1102 Register-Level Programming Manual

The SCXI-1102 User Manual refers (in Chapter 5) to a "SCXI-1102 Register-Level Programming Manual". I can't find the register-level programming manual on www.ni.com. Where can I obtain this manual?

Hey Don,
Thank you for contacting National Instruments.
There is not a register-level programming manual for the SCXI-1102. This was a mistake made in the first version January 1996 of the SCXI-1102 manual. This was corrected in the later August of 1997 version.

Register Level programming of the AT-DIO-32HS

I am working with a piece of software that was written using the AT-DIO-32F card. The original programmer did NOT use the National Instruments driver with that card, but rather used a software library that allowed him to access and manipulate the registers directly on that board. The name of the library is called NTPORT (http://www.zealsoft.com/ntport/index.html). He did this because he was not able to meet the timing requirements using the NI driver.
We have to replace the AT-DIO-32F card with the AT-DIO-32HS card, and I would like to know if I can continue to do register level programming with the 32HS card. I have found that I also can not meet my timing requirements using the driver that comes along with the 32HS card.
I checked this web page (http://digital.ni.com/public.nsf/allkb/B08F4125A9325B3F862565CC0073E68F?OpenDocument), and did not find the AT-DIO-32HS listed. Does this mean I can not program its' registers ?
Any feedback would be appreciated !!
Thanks !!

Hi Raminta-
The Measurement Hardware Driver Development Kit (MHDDK) provides examples and register documentation for the 653x devices (which includes the AT-DIO-32HS). The DIO-32F and DIO-32HS devices are quite similar, so it is possible that your existing code will work. The resources on the MHDDK page should help you fill in any differences.

Register level programing of the 6601 counter to connect signals to the rtsi bus

I have need for more than 4 clocks and have several 6601 counter boards. I would like to use an additional board for the extra clock but need to send signals to the this board from the other. The most efficent way seems to be to use the rtsi bus to connect the 2 boards together. I am programing the counter boards at the register level using a kernel module in linux. The register level porgramming manual explains how to connect different signals to the sourse pins of the clocks including the rtsi signals. I have been successful in doing this but can not find info on how to route the output signal of one clock to the input of another using the rtsi bus. Using web search I have seen ways to do this using labview and dqmx calls but nothing for programin at the register level. Thanks for any help on this problem.

I can not load i Tunes on my laptop running windows 7 I get a message that the installer has insufficient priveleges to access this directory C:\Program Files\ i Tunes

I have tried reducing the pop up level on my browsers. No change.

That one's consistent with disk/file damage. The first thing I'd try with that is running a disk check (chkdsk) over your C drive.
XP instructions in the following document: How to perform disk error checking in Windows XP
Vista instructions in the following document: Check your hard disk for errors
Windows 7 instructions in the following document: How to use CHKDSK (Check Disk)
Select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors, or use chkdsk /r (depending on which way you decide to go about doing this). You'll almost certainly have to schedule the chkdsk to run on startup. The scan should take quite a while ... if it quits after a few minutes or seconds, something's interfering with the scan.
Does the chkdsk find/repair any damage? If so, can you get an install to go through properly afterwards?

How to use PCI6602 4-5 cards run simultaneous via RSTI?

I use them as a simple event counter all of them must start and stop count at the same interval of time.

Hi credo,
First here's a few comments on what I see in your vi:
1. The loops to configure the counters are the right idea. You need those 32 distinct task id's to perform 32 channels of counting. You've already gotten over one key hurdle!
2. There's quite a bit of duplicated code to handle each of the 4 boards separately. You could make sub-vi's out of these code chunks and clean up your diagram considerably.
3. You're programming the counters for "simple" (unbuffered) event counting but are then reading them as though they are buffered. This won't work.
I can't tell whether you need buffering or not. It doesn't look like you are trying to use most of the buffered data. However, buffering *can* still help make sure that all the counter values you read represent the same instant in time. Can you describe your needs more exactly?
4. If you buffer the reads, you'll need to supply a "Gate" signal, i.e., a sampling clock. If you can spare a counter to generate one, then this alone can synchronize all your readings. Otherwise, you'll also need to configure all the counters to start on a digital trigger.
5. You've got some issues with dataflow, local variables, and race conditions. For example: inside your big loop you read from the D1,D2,D3,D4 local variables to create a graph and stuff. However, you don't write new values into those indicators until the inner reading loops end. It is very likely that they will be read before they are written. This would be a good place to simply route wires instead of using local variables.
That's plenty enough to look into for now. I would strongly recommend that you first try to work out the programming syntax and flow using several counters from 1 board. When you get it working, you can create a sub-vi from it and reuse it for the other boards. Then we can start talking about RTSI...
One little-known fact about RTSI is that it can actually be handy even when programming a single board under traditional NI-DAQ. I've used it frequently to avoid the need to hardwire connections for timing signals. I'd again recommend that when you're ready to deal with RTSI, that you first try it out on a single board. If it works for 1 it'll work for the others.
Finally, you may want to consider migrating to DAQmx. Especially if you don't have a lot of code invested into counters under traditional NI-DAQ yet. NI has been nudging us toward DAQmx for quite a while now, and it'll handle the RTSI stuff pretty much auto-magically.

DAQmx non-cumulative buffered edge counting (like the PMT TTL problem) with PCI6221 in C program environment

I have a PCI-6221. I am programming in C/C++ and DAQmx. My application is much like the previous thread counting the number of asynchronous TTL pulses from a PMT in some user specified time interval. The time interval is typically around 1 msec and the signal rates are around 1-10 kHz. So I expect to count 0 to 10 pulses per timebin. In traditional DAQ this was called Non-cumulative buffered edge counting.
To get a clock at about 1kHz, I first create an "analogue in" task that samples at 1kHz. The only thing I use this task for is to route its sample clock to the gate of the counter. This defines my time interval as 1 msec.
I then create the counter task. I am using count edges. So I think counter0 gate = PFI9 and source = PFI8.
DAQmxCreateCICountEdgesChan(*taskHandle,chan,"",edge,initialCount,countDirection);
DAQmxCfgSampClkTiming(*taskHandle,clockSource,rate,DAQmx_Val_Rising,DAQmx_Val_ContSamps,samplesPerChan);
where clockSource="/Dev1/ai/SampleClock"
I apply my signal to PFI8.
After starting the task, I read an array of values with
DAQmxReadCounterU32(taskHandle,samplesToRead,10.0,data,samplesToRead,read,NULL);
I expect the array data to have values ranging from 0-10 for PMT input with an average rate of about 10 kHz. The trouble is that the array data does not seem to make sense. I get constantly increasing values. For very low input frequency, it just increments by one per array member.
More troublesome, when I hold PFI8 at ground, so that I expect zero pulses to be counted at the source for each edge at the gate that occur 1 per msec, I get a timeout error. I really must be able to count zero events per bin.
Am I doing something obviously wrong?

Hello,
The behavior of non-cumulative event counting is equivalent to period measurement. Additionally, the timeouts when no edges occur on your event counting terminal are the result of duplicate count prevention. In DAQ 7.4, the default behavior of duplicate count behavior should take care of this for you, but if you cannot upgrade to DAQ 7.4, I'd do a search of the discussion forums for "duplicate count prevention". There are a number of previous posts about this attribute, including this one.
If you aren't using the second counter on your device, you should be able to use the Period Measurement 2 Counter High Frequency measurement method to get your desired values. The "Measurement Time" attribute in this case would be the "sample clock" (1 kHz in your example). Then just raed the data raw to get counts rather than scaled.
If you'd like to do it using the AI timing engine. Configure a 1 counter period measurement task, use "clockSource" as your input terminal and use your PMT TTL pulses as the "Counter Timebase Source". Then read the data raw, since the scaling will not be appropriate for your needs.
I hope this helps!

Can't get counter 2/3 working in simple event counting mode for NI6601

I have been successfully been able to get counter 0 and 1 working in a simple event counting mode. But when I read Software Save register for counter2/3 it gives me garbage values. I am doing register level programming in C.
This is the algorithm that I follow
In initialization:
-> Reset the Counter
-> Write32( Clock_Config_Reg, 0x00)
-> Write Load A and LoadB registers
-> Write to Input Select Register with appropriate values
-> Write16( Command_Reg, 0x0125);
Then when I need to read the SW save register value
-> Write to Command Register setting the gi_Arm bit
-> Reading the SW save register twice
-> If not equal ,read again
-> Write to Command Register disabling the gi_Arm bit
This works just fine for counter 0 and 1. But I can't get it working for counter 2 and 3. Are there any other registers I need to set up correctly for counter2/3. Is the default reset values of registers different for counter 2 and 3?
Any help would be very appreciated
Thanks

Hello manisha,
Is there a particular reason for using register level programming to interact with your DAQ card, rather than the DAQmx driver? The reason I ask is because we don't support RLP at NI. There are some manuals that have been developed, such as this one which corresponds to your card, but I am unable to offer any support after that. If it is necessary that you must use RLP then you should post your question to the DDK forum, as they have more experience in this area.

When running setup, I get"This file does not have a program associated with it for performing this action. Please install a program or, if one is already installed, create an association in the Default Programs control panel.

whe I try to install Firefox 4.0.1, I get a Red X message. ""This file does not have a program associated with it for performing this action. Please install a program or, if one is already installed, create an association in the Default Programs control panel. Is there a fix?

I Did that. When I try to install, I get the same message. I have come to believe this is a windows 7 or IE 9 problem. I also have active X problems that I can not resolve. I can not open Gmail also

System Overload & How to get the best G4 Performance

Okay all you Logic and OSX Gurus. I need your help. I've finally made the LOGIC leap from OS9 and have hit the SYSTEM OVERLOAD wall like many of you before me.
I've been pouring over this, and many other Forums and Blogs, for about two weeks now, and have tried many of the fixes / solutions to no avail. I estimate I'm now getting about 25% of my OS9 Logic performance from Logic in OSX.
One specific case in point is this. A four minute song sketch. No tempo changes. Four midi tracks, 6 Audio instruments and 2 EFX (1 Guitar Amp Pro, 1 Space Designer that's no even being used).
I have unsuccessfully tried to Bounce this to disc for two weeks now. The AUDIO and DISK I/O Meters barely register until the GUITAR AMP PRO track brings the AUDIO METER up to about 1/3rd usage. At various points in the Bounce the G4 will completely FREEZE, and I will have manually restart.
THINGS I HAVE TRIED, and continue to try are:
- Repairing Permissions
- Trashing Preferences
- Updating MOTU Drivers
- Changing Processor performance setting - which I cannot do BTW, because my system does not seem to support this option.
- Closing all Widgets
- Freeing up more Space on my Mac OSx startup disk (I now have 78.41 Gig available on a 114.49 Gig drive)
- Run Cocktail to clean up System logs and temporary files
- FREEZING TRACKS as a temporary 'fix'. This did nothing BTW but add more strain to the CPU and I still had about 1/3rd the usage with my GUITAR AMP Plugin (and it still crashed).
- Increased AUDIO BUFFER to 1024
So, (and I guess this is really two sides of the same question)...
1) How do I FIX this SYSTEM OVERLOAD problem, and
2) How do I "optimize" my Dual 1.25 G4 in order to get the best performance possible out of LOGIC PRO?
OTHER QUESTIONS I HAVE ARE:
- Does the G4 have the processing power needed to run LOGIC PRO?
- I'm confident adding RAM will "help" (can't hurt), but am I really dealing with a RAM Problem here or, again, can these processors really handle it?
BTW - I'm not looking for an excuse to go shopping for a Quad G5 (I mean who needs an excuse... . But, I'm really trying to determine if at the end of the day I will spend money on RAM, Hard Drives, whatever..., and then still be frustrated and end up shopping.
- Are SCSI drives a problem with Tiger / Logic? These Cheetah drives are fast (10,000 RPM), reliable, and have been great drives to record on. I'm trying to do this simple bounce to one of the Cheetahs and as I said it's just not happening.
- Does the startup volume size effect performance?
- Does the amount of free space on the start up drive effect performance?
- Firewire 400 vs 800? My sample library is on the Firewire drive, and I'm thinking this does not pull a lot on the CPU as these get loaded into memory before playing? Am I right about that? It is Firewire 400.
A long letter and a lot of questions. I thank you all in advance for any answers, guidance or direction you can give. Please also let me know if there is something I HAVEN'T asked, looked at or should be doing.
Best,
Kevin

And after months of using Express, and a week of
using Logic, I hadn't had a system overload until
today. Now I'm having them all the time. It wasn't a
set up change, it wasn't running on the battery, it
wasn't running software monitoring, it's set up with
512 i/o buffer, medium processor buffer. And it
wasn't brought on by number of tracks - that's for
sure. After it started happenind and I took a break &
came back, I was sitting on my couch, Powerbook in
my lap, tapping a beat in with the onscreen
keyboard.... a SINGLE instrument, mind you. NO plugs,
no other tracks of ANY kind. And it happened.
There's a lot of great, relevant and very helpful info on this forum and it all helps and it all counts. But..... so many people are suffering this when moving up to Pro 7 from either Pro 6 or Express. One expects a change in system load when a major update comes along but more and more people are reporting that simply recording 1 or 2 tracks of audio, pure, no plug-ins or EQ is causing an overload whereas in the previous version(s) this was easily accomodated. This, you may have guessed, has happened to me as well. Are we to accept in 1 version increment (albeit a major one) there is such a massive increase in demand from hardware that you cannot record a pure no-plug-in stereo track? When going back to 6.4.3 it will happily record 8 at once, let you EQ and reverb and then do another 8 AND then another. With no troble at all.
It is pointing more and more towards fundamental flaws in the programming. Did L7 come out too soon? Are we just beta testing what is pro software? We are only on 7.1.1 and 6 went to 6.4.3 but at no stage was it this bad at the fundamentals of what the App is for. I love Logic, I really do, but I think, even with all the great help we are fighting what Apple should be addressing. Not that you can find/contact/talk to or get any sort of response from them.
I have tried but have gone back to 6.4.3 until 7.1.2 or even 7.2 appears, but I'm not paying for 7.2. My £200 upgrade from 6.4.3 is now sitting on a shelf desperately wanting to use it.
