TI 2407 DSP TO PCI-CAN 2 (high speed card)

I'm trying to interface the national instruments PCI-CAN2 (high-speed CAN) to the texas instruments TMS320LF2407 CAN module. How can I make the two CAN modules communicate(c Lang)? Also the TMS320LF2407 DSP does not support the RTDX interface so the dsp toolkit will not be useful in my app since I'm not allowed to use memo i/o to monitor. What do I need to do in the code composer environement to communicate back and forth with the can on dsp board (any example code or docs in c will be appreciated)
could anybody please point me to a starting point
Thank You very much

Hello,
I am not familiar with your TI CAN module but I can help you with the configuration of the National Instruments PCI-CAN Card. A helpful reference is the PCI-CAN user manual located here:
http://digital.ni.com/manuals.nsf/websearch/6BF77910C5528D4486256D63004EDE1F?OpenDocument&node=132100_US
You first need to physically wire the two devices together as shown in chapter 4. Next, you should use some of the example programs to get you started programming in your desired language.
The CAN standard will allow you to communicate between your TI module and your PCI-CAN card, but the format of the data is up to the TI module. You might need to send a "remote CAN frame" to get data back, or the TI module might send data continuously. The data that you
receive will need to be somehow interpretted, and this is where you will need the help of TI.
Hope this gives you a place to start. Even if you do not have the card at this point in time, you can download the driver and take a look at the API and the example programs by downloading it here:

How to use PCI-6534 High speed DIO to count the no.of pulses aquired

HI All
I have PCI-6534 high speed DIO card. My requirement is to count the no.of pulses coming. Here i have an energy meter which generates pulses with frequency of around 8MHz. i need to cunt the no. of pulses coming in, here i am attaching the VI i am using. I could not really count all pulses coming in. right now i am using single line, but the requirement is to develop for 7 lines. I do not know where i am going wrong. Can any of you help me in this regards.
Thanks

Sorry, not near a LV PC so can't look at your vi now. Are you limited to using only the 6534? If all you need to know is the count of pulses from each of the 7 ~8MHz sources, it seems like the amount of data storage required with a 6534 is terribly inefficient. Since the 7 sources are unlikely to be synchronized in any way and they are each at ~8MHz, you're looking at about 100+ million transitions per second with change detection. I don't think the hw can keep up with that. Even using a constant sampling rate of 20 MHz (which just barely satisfies the Nyquist minimum of 2x 8MHz), it's questionable whether you can keep up with that rate for several minutes. Even supposing the hw and your PCI bus and software can keep up, there's still a TON of processing to do. 20 MB/sec for 20 minutes = 24 GB!
On the other hand, consider the 6602 counter timer board. Here you would simply set up 7 edge counting tasks, probably without any buffering at all. At any leisurely pace you want, you can software query the counts of the # of pulses on each of the 7 channels and have an instant answer. The only issue to deal with is that the counts will rollover when you reach 2**32. At 8 MHz, this will happen about every 9 minutes. However, DAQmx provides a nice way to handle this. There's a property you can query that will tell you if a rollover has occurred. It automatically resets itself to False after you read it so it's ready to detect the next rollover 9 minutes later. See my first post in this thread for example. (Last I knew, only DAQmx does the automatic reset, not traditional NI-DAQ).
If you can possibly buy a 6602, I'd highly recommend it.

USB 2.0 high speed card won't run Canon MP800 printer

I have a Power Mac G4 AGP graphics. I installed OS X 10.4.4 on it. I purchased a new Canon PIXMA MP800 multi-function- printer. It needed a USB 2.0 high-speed connection. I purchased an Allegro USB 2.0 high-speed adapter card and installed it in my empty PCI slot. Here's my problem: When I connected the Canon printer, it would not print or scan.....it just went through the motion of sending, but not completing the task. I called Canon to trouble shoot the problem. I connected the Canon printer to my native USB 1.1 port and it worked fine. I then, removed my PCI card and reinstalled it, to be sure that it was seated correctly in. The Canon still would not work. So I plugged my old HP 1200C printer(USB 1.1) into the USB 2.0 port and my printer did work, but at the USB 1.1 speed. I contacted Sonnet Technology on the Allegro USB 2.0 PCI card and they said to try a utility called Cocktail or Tiger Cleaner to try and fix the problem. I downloaded Coctail and ran it to see if this would work. It didn't fix my problem. Any suggestions?

what type of USB 2.0 PCI card did you put in? have a look at the card and find out what chip is on it and let me know. I put one in mine that has the VIA VT6212L chip in it and it doesn't work either, despite OS X having native drivers for USB 2.0 cards.
The USB ports on my card didn't work at all until I installed a driver that I got from VIA. Even then though only 1.1 devices work while the 2.0 devices are not even recognised.
From what I hear, adaptec brand USB 2.0 PCI cards are what you want to get in future, plug them in and off they go (wish I'd done my homework). No messing around with drivers that support only half your new hardwares features.......of course its the other half that you actually need.
I've spent hours reading through all sorts of info and scanning forums everywhere to try to find a fix, I understand why you're a little woozie. A possible fix that people seem to keep suggesting is to zap your PRAM (restart holding command-option-P-R keys, don't release the keys until after the 3rd chime), didn't help me and I doubt it'll help you but at least when people tell you to try it you can say you've done it.
here's my post to my problem:

How to simulate testing of PCI 5114 high speed digitizer

I want to use PCI 5114 board and want to interface it with LABVIEW 6.0 using NISCOPE VIs. I am a beginner to NISCOPE digitizer. I want to test my small application made for 5114. I don't have 5114 at present. Kindly tell me how can I simulate this boards and its input and Ext trigger.

Thanks Mr. Nathan.
My previous two posts were for me to understand how to check an application I had developed in LabView. As digitizer card is not with me at present so still some doubts are there. Let me specify in brief what I want and how I am achieving.
A repeated pulse signal of given duration (10 microseconds) at channel 0 is to be acquired. Repetition rate is decided by the trigger pulse available at Ext. Trigger. More clearly when ever trigger pulse (approx. Every 100 microsecond)) appears I have to acquire Channel 0 signal for 10 microseconds. Sampling rate is 100 Mega Samples per second.
I have used following blocks in given sequence: Initialize with Options (for simulation), Configure vertical, Configure Horizontal (sample rate=100MSPS, rec length=1000, num of records=1, ref positon=0), Configure trigger (edge, level=0.1, source Ch0 (for simulation purpose)), Initiate Acquisition, Multi Fetch WDT (num samples=1000).
Please tell whether I have to put Initiate Acquisition, Multi Fetch WDT Vis in while loop or only Multi Fetch WDT in while loop so that I can fetch all the data on each trigger.

How do I set a low baud rate using a High Speed CAN board?

I have a PCI-CAN/2 board, and I want to use one channel for a 500kb/s network and one channel for a 33.333kb/s network but I keep getting a baud rate error. Is it possible to use such a low baud rate or is there a lower limit?
Thanks

I would recommend to post CAN related questions to this board.
According to page E-2 of the user manual, the min baud rate for a PCI-CAN high-speed CAN interface is 40kbps.

High speed and Low Speed CAN

Hi
This is my first time to use CAN.
I have LabVIEW 2010 and LabVIEW FPGA
I have NI 3110 Dual-Core Industrial Controller with Windows OS, NI 9157, NI 9852 CAN Low Speed Module and NI 9853 CAN High Speed Module to be used to monitor the CAN messages from an ECU unit.
The connection is done as the following:
·         The High speed CAN is connected to the NI-CAN 9853 (Port 0)
·         The low speed CAN is connected to the NI-CAN 9852 (Port 0)
·         The baud rate of the 9853 is 500kbps
·         The baud rate of the 9852 is 50kbps
·         Both modules are set to “Listen Only”
·         “Module Clock” in both modules is set to 20MHz
·         CAN networks are 29-bit and 11-bit.
My consideration is to read all the messages from both modules without losing any message. Below is a picture from the block diagram on the FPGA target, is this the best way to read CAN messages from both modules? Also, could you please suggest what is the best way to read the messages on Host vi?
Unfortunately, I do not have the module right now to do some test, so that I cannot get the iteration time (“CAN Low Speed Loop” and “CAN High Speed Loop” show in the picture below), could you please tell how to calculate the iteration time needed for each loop depending on the above information.

The way that you have proposed to use the CAN module to monitor the BUS is a bad idea. We have a prebuilt driver that will do most of this work for you. You will need to download and install the NI-CAN 2.7.3 and then you will be able to use the example finder. In the example finder look for.
The example finder is accessed through the Help menu.

Query on PCI-CAN????

Hi,
This is Harish Chincholi, new to this community.... Currently I am doing my master's programme(M.Tech)... I have been assigned a project on PCI-CAN... its Cross Channel data link using PCI-CAN... In which there are around 4 PC's Connected and data needs to be transmitted by 1 PC and simultaneously should recieve by rest 3 PC's... So I need to know how many PCI-CAN cards do i need to perform this demo. and any particular model(PCI-CAN type).. keeping in mind the cost factor...
Thanks & Regards,
Harish Chincholi,
Project Trainee..
Kudos! Thanks!

Hello Harish,
You will need a PCI-CAN card in each PC. A single port high speed card should be fine for this application. If cost is an issue, you can also look at the USB-CAN modules. Please note that these modules do not support the Channel API, so if you just want to send raw CAN frames from one computer to the three others, this would do.
Please let me know if you have any other questions or need more information to make your decision.
Have a great day.

Where can high-power video cards be installed on a first-gen Mac Pro?

I have a first-gen Mac Pro with a Radeon X1900 XT in Slot-1 and a Geforce 7300 GT in Slot-4. The x1900 XT powers a 30" monitor and the 7300GT powers 2 x 20" monitors. The 7300GT card died and is being replaced with an 8800 GT.
Now it seems fairly obvious that for gaming the 8800 GT is superior to my X1900 XT. Ideally I'd like to just throw my new 8800 GT in Slot-1 and use it for my 30" monitor and then run the 2 20's off the X1900 XT in Slot-4. The problem with that is that the x1900 XT is a huge card and physically won't fit in Slot-4 because it runs in to the hard drives above it.
*Now, on to the questions / clarification:*
_Question 1_: Is the first-gen Mac Pro the same as the new Mac Pro in that high-power cards can only be used in Slot-1 and Slot-2? If so, why does it come in the standard configuration of:
Slot-1: x16
Slot-2: x1
Slot-3: x1
Slot-4: x8
It would seem that Apple purposely did this so you would run 2 high-power cards in Slot-1 and Slot-4 and keep them away from each other for heat reasons. The new Mac Pro has x16 bandwidth on Slot-1 and Slot-2 and it would make sense why they say to only install high-power cards in Slot-1 and Slot-2 for it.
_Question 2_: PCI-e configurations. There are a few ways I could tweak the configuration of the expansion slots to make this setup work. I'm curious as to which you would think is best:
*Option 1 (default PCI-e config, only works if a high-power card can be installed in slot 4):*
Slot-1: x16 - Radeon X1900 XT - 2 x 20" monitors for minor tasks / programs
Slot-2: x1
Slot-3: x1
Slot-4: x8 - GeForce 8800 GT - 30" monitor for major tasks / gaming
Now, the first issue is can the 8800 even run in Slot-4 due to the supposed power problem? If so, would there be a difference in performance for gaming at x8? I know this is backwards because you'd want the "primary" card to run on x16 but that's just not possible with this PCI-e configuration. If there is a difference in performance would an 8800 GT at x8 still run significantly faster in games than an X1900 XT a x16? I'd think so, but that's assuming the x8 isn't a real bottleneck.
*Option 2 (the only solution if the cards have to be installed in the first 2 slots):*
Slot-1: x8 - GeForce 8800 GT - 30" monitor for major tasks / gaming
Slot-2: x8 - Radeon X1900 XT - 2 x 20" monitors for minor tasks / programs
Slot-3: x4
Slot-4: x4
You still have the issue of the 8800 only running at x8 (if it even makes a difference, not sure). The benefit I see here is that instead of the X1900 XT dumping all of it's heat in to the 8800 GT (since heat rises) you have the 8800 GT on the bottom where it might run cooler. The X1900 XT would then also be limited to x8 but it's not even being used for gaming so it wouldn't matter at all. The X1900 XT is huge and would cover up Slot-3 but I don't use the other 2 slots so I don't mind.
*Option 3 (only works if Slot-3 can actually power an X1900 XT):*
Slot-1: x16 - GeForce 8800 GT - 30" monitor for major tasks / gaming
Slot-2: x1
Slot-3: x4 - Radeon X1900 XT - 2 x 20" monitors for minor tasks / programs
Slot-4: x4
This seems ideal only because this is the only setup that can get the 8800 to run at x16. The issue now is can Slot-3 run a high-power card? The card doesn't really NEED the power since it's just for running basic apps and not gaming. Again, the X1900 would cover up Slot-4 but it's not being used so no worries there.
*At the end of the day, the most important thing to figure out is:* where can high-power cards be installed in a first-gen mac pro? Once we know that we can figure out Question 2. The instructions that come with the 8800 GT say it can be installed in any of the 4 slots, but I don't know if I really believe that.
Thanks in advance for your help!

Thanks for your help, I think we've beat this horse to death :P. I'm glad I got it all figured out though.
Now the only question is if the gaming performance of the 8800 is actually enough better than the X1900 to warrant making it my "primary" video card. As long as Adobe CS3 apps don't rely on core image like some of the Apple Pro apps do I think it will be fine. If they do I'd have to probably just stick with the X1900 since I use CS3 every single day and only play video games once a week if I'm lucky.
What are your thoughts on the X1900 vs the 8800 GT for CS3?
Edit: This just occurred to me... Since I'm going to have to run them as x8, x8, x4, x4 there isn't really going to be a "primary" card since neither will be at 16x. I guess I could technically just plug my 30" monitor in to either one of them depending on what I feel like doing. If I'm going to play a game I just plug in to the 8800 and if I'm working I plug in to the 1900. The computer is up on the desk so moving the monitor from one card to the other takes about 10 seconds. I could just plug 1 20" monitor in to each so there's always a free DVI port on either one.
It's not the most elegant but I guess it would be a good compromise if I wanted the "best" performance in either situation. I realize the Radeon 3870 is probably the best of both worlds but I really don't want the noise. I already modified my 1900 with this after 6 months of listening to the lawn mower that was the stock 1900 cooler: http://www.arctic-cooling.com/vga2.php?idx=147
I'm just hoping the 8800 isn't too loud .

How can a session be setup between two MacBook Pro's at different locations on high speed Internet connections, be setup to have a live recording session in Logic?

My partner and I live on opposite sides of the valley here in Phoenix. About 50 miles apart one way. We are Musicians and are working on a commercial for television, and would like to know if there is a way, between FaceTime and Logic, that we can configure our MacBook Pro's to record sessions together without having to be at the same house? When we FaceTime, he can hear my keyboard through his headphones, but we can't seem to get the signal routed into Logic and register to a track when its record enabled. Is there a way for us to save gas, and record at seperate locations, so he can engineer me and I can engineer him, while we build this project in Logic and Final Cut? Here is what we are using, we have nearly identicle setups, which was planned so we might be able to do something like this. Both of us are using Mid 2012 15" MacBook Pro's with 2.6GHz Intel i7 processors and 16GB RAM. The only difference between the two MacBooks is that his has an Optical Drive, but I removed mine and replaced it with a 2nd SSD Drive, so I have two Samsung 840 Pro's each with 512GB in my MacBook Pro. His just has one Samsung 840 Pro with 512GB. We both use Focusrite Saffire Liquid 56 Firewire Audio Interfaces, and we both use Logic Studio 9 Academic. I don't know if you need to know what we are using in order to help us figure out how to configure the MacBooks for a live session, so I figured I would give you those details just in case. If you need any more information, just let me know? Oh, we both have high speed cable Internet connections. Mine is 150Mbps speed which is the absolute fastest I can get in my area. And his is only a 50Mbps speed line.
Again, what we are looking to do is have a LIVE recording session, in Logic, with him at his house and me at my house. When we FaceTime each other, we can pretty much hear each others keyboards as if they were part of the conversation, and as crystal clear as we can hear our own when recording, but we can't seem to record enable an Audio track in Logic and route that keyboard signal into Logic and record it so we can engineer each other without either one of us having to drive to the others house, to be there to do it. If any of this even makes sense, I'm not quite sure how to better explain it. So hopefully you get what I mean, otherwise just say so, and I will try to do a better job explaining it. :-)
Anyone who can help us with this little problem would be greatly appreciated, and quite a hero in these two humble Musicians Worlds!! So from both of us, THANK YOU in advance for any input you might be able to give us. I look forward to hearing any and all suggestions.
Scott

Hey Scott
You and ALOT of people are attempting to do this, myself included.
Unfortunately at this point (to my knowledge) it's a pretty CRAP setup involved that will likely leave you frustrated.
HOWEVER:
A few things CAN be done:
IF you are getting live audio from your partner over the internet, you can re-direct that audio directly into Logic using a program called SoundFlower.
There are a few alternatives to SoundFlower, like JackTrip, and.....(the name eludes me)
(SoundFlower is from a company called Cyling 74 who also makes Max MSP. )
Once in Logic, you set your audio inputs to the track to be Soundflower. (either 16 inputs, or in this case 2)
That all being said, regardless to speed, you are still going to experience latency in the connection, and THAT is the part that will likely drive you to the mad house.
THIS all being said, I believe there are websites out there that are set up to actually do this kind of thing, (at least there WERE) but likely membership costs, and other "hidden" problems that you only learn about after you have signed on the dotted line. (Hopefully I am wrong?)
If you don't need to do a "live jam", there are always solutions like DropBox that work very well for exchanging large files quickly.
If you want to record live MIDI input from his keyboard, I am unaware of any solutions for this.
Due to the popularity of the iPad, you might want to look into the App store, and see if there is something available.
Good luck!

How can I stop spam from someone called AT&T High Speed Internet? I do not know what the email address is.

I am receiving 100's of spam emails. They are all advertising different types of products but they all say they are from AT&T High Speed Internet. I have used the junk filter on them but it does not pick them up as junk. I have to do it manually each time. I have contacted my UVerse provider and they cannot assist because it is getting through Yahoo to Thunderbird. They say that it is a problem that I will have to have assistance from Thunderbird to resolve so that I can have this listed as junk and will not have to do this manually. I am at my wit's end. Please, please help me!

Yahoo has its own junk mail filter (Spamguard), which you should confirm is enabled:
* [https://help.yahoo.com/kb/mail/stop-spam-yahoo-mail-sln3227.html Mail Help | - SLN3227 - Stop spam in Yahoo Mail]
The significance of this is that marking messages as junk in Thunderbird probably isn't integrated with Yahoo's system, so Yahoo may not be getting trained to block them. You might need to go into Yahoo from time to time and mark accumulated junk as spam.
Separately, there are solutions for filtering spam on your computer as the mail is downloaded from Yahoo. Thunderbird has a built-in filter, as described here: [[Thunderbird and Junk / Spam Messages]]. However, if that isn't as effective you would like, there are third party products as well.

How can I set up a home wireless network with Comcast high speed internet?

I just signed up for Comcast High Speed Internet. I was able to get my Power Mac onto the internet. However, I connected my Airport Extreme and am unable to get it to recognize that I have an internet connection. I want to set up a wireless network in my apartment. Comcast tech support said that I only have one IP address.
Any suggestions as to how I can get my wireless network up and going? Thanks!

Should I change set up so that cable goes from the cable modem directly to Airport Extreme and then use the ports on the Extreme to run Ethernet Cable to Power Mac and other devices?
Yes
As an aside, would this setup allow me to hook my iBook up to Airport via Ethernet cable and let it get into Internet that way?
Yes

Can I convert an old IMAC computer with OS 9 operating system from being "dial up" to high speed?

Can anyone tell me how I can convert my old IMAC from "dial up" to go on the internet as high speed? I have an ISP provider for a more modern computer that I own, but I really would like to use my old IMAC on the internet as well? How can I make it compatible with high speed internet? If I try to go on line, the internal modem "dials up". How can I change that and cause it to communicate with my external high speed modem?

Any iMac can connect by ethernet to the router.
You'll need to disable the modem and set up the network config.

Can a G4 Desktop OS 8.6 be hooked up to cable modem high speed?

Can anyone help me set up my apple G4 desktop os 8.6 to work with a high speed cable modem to get internet access?

Hi Gepicou
In a word yes, your G4 will definitely support a high speed DSL connection - I'm writing to you on a 7300 powerPC mac I've just dusted off, sent to a repair shop where they set her up for my 512Ko line. I'm deep in the countryside so I don't get a powerful signal, but all is fine. The modem is a Thompson 510 (ethernet).
Normally I use my present Powerbook running on Panther, and since I'm going to England for work reasons, I'm leaving my partner with my old (and dear) Mac to use.
You could try the forum "Mac OS 10.3" > getting online - loads of folk there have used OS9 before, and have experience in newer connections that weren't really around when OS8 or 9 were still mainly in use.
Otherwise, if you get your running orders from that forum, take your G4 to a technician - mine configured the modem in 20 minutes, it cost me 20 euros...
Good luck!
