USB to SPI Converter

HiI'm trying to use USC-216 Isolated USB to SPI Converter with Labview.But I can't communicate with the unit Is someone familiar with this converter?Best regardsGuy
Solved!
Go to Solution.

Sorry about the late response
I don’t have sample code but after I created inf file with NI driver wizard I managed to see the device by using VISA.
Now my problem is that there is no response from the device
The device is in bulk mode using endpoint 0 for enumeration, endpoint 1 for reception (IN endpoint) and endpoint 2 for transmission (OUT endpoint) Can you help me?
Thank's

USB to SPI

Hi
Can we read USB device using Labview 8. Our application can be better explain with the help of attached block diagram. Please find the attached Document. In this application , we are using a sensor having SPI interface.Then with the help of National Instruments USB to SPI converter we are interfacing it with the PC.
My question is can we read the data from a sensor which is connected to PC using NI USB to SPI converter.
Please reply as soon as possible since it is very urgent.
Thanks & Regards

Hi
In one of our application I have to read the internal register values of the sensors. I am using NI 8451 card.
Pin Details of the sensors are-
SDIO – Serial Port Data Input & Output
XY_LED – Led Control
NRESET – Reset Pin (active low input)
NCS – Chip select (active low input)
VDD5 – Supply voltage
GND – Ground
REG0- Regulator Output
SCLK – Serial Clock Input
My question is NI 8451 is having separate pins for SDO & SDI But sensor is having one pin for SDIO. How to connect them ,I have to read the register values & some registers are read/writable.??
Please reply as soon as possible, it is very urgent

I2C data send using USB-to-I2C converter

Hi guys me again
Just when things started to look good another trouble comes
We thought we will buy NI-8451 to implement I2C. We contacted NI also but suddenly another student comes and says we can implement I2C using Devantech USB-to-I2C converter..
Can it be implemented using VISA(all operation of I2C like read, write, ack, clock stretching)???
Thanks in advance

I never used that device, but ran across it while searching for alternate I2C and SPI devices. That uses a standard FTDI interface chip, so the device shows up as a serial device. So, yes, you'd be able to use VISA to communicate with it. Please check the documentation for the device in the future.

USB to 422 Converter Woes

I have a USB to RS422 converter that was packaged with an IMS MDrive 23 stepper motor controller. I probably should have bought the NI Converter as I
can’t get LabView to write to the port. The device is nicely packaged with a
driver that makes it appear in Device Manager like a standard serial port.
M&A Explorer seems to like it and will open a VISA session.
I can’t get past the LabView standard VISA Write command. It issues a
“Could Not Perform operation because of an I/O error" or a “The specified
attribute is not defined or supported by the referenced resource" error.
When I reboot the motor controller, it issues a “reboot successful“message
that can be read from the port from LabView, so I am communicating with the
port and controller in one direction.
Without changing anything, HyperTerminal communicates
successfully.
Any ideas will be cheerfully and thankfully appreciated.

I have used the IMS converter with Labview, but only to test basic comms. If I recall, it echoed back the command, but I believe that can be disabled in the MDrive.

USB to Parallel Converter

Has anyone had success using any USB to parallel port converter? I've tried 3 different cables including one that supposedly supported the full IEEE-1284 standard, but all of them show up only as a virtual printer port. Is there a way to get access to this port through LabView? Are there any cables/converters out that actually show up as a regular parallel port? I've searched far and wide for one, but had no luck. I searched the boards to see if anyone had done this, but most of the posts were over a year old and had no resolution confirming whether or not a proposed solution worked or not. Thanks in advance for any help,
Travis

What OS are you using? I had the same problem with XP and LabVIEW 7.0 & &.1. But using the same USB-parallel port converter under WIN2k I was able to access this as a parallel port. In the end my solution was to go to a PCI parallel port which worked fine under both OSes.

USB to SATA Converter

Hi,
I would like to upgrade the HDD of a MacBook Pro to a Solid Sate Hybrid Drive (MacBook Pro 5.1 late 2008). Before removing the original internal HDD I would like to install the Mac OS on the new drive, make sure it works ok.
I have looked online and seen different USB to SATA converter cables. Some come with 1 USB port, some with 2 USB ports, and some even with an external power supply. Any suggestions?
Thanks,
Pablo

Any cable configuration that recognizes the external HDD will work.
I recommend that you use Disk Utility>Restore or Carbon Copy Cloner to copy the data from your current internal HDD.
Do not for get that the new drive will have to be formatted first in Disk Utility>Erase to Mac OS Extended (Journaled) before the cloning.
Ciao.

Usb to 232 converter and windows 7

Hi All,
Taking a long shot hoping someone has an idea on what the possible solution could be. Hoping I've just missed something obvious. I have a customer who is using the NI usb to 232 converter. The software he is using is emh camcal software. He says the comms worked fine on his XP machine, then he moved it across to a machine with Windows 7. He installed the latest driver, NI serial 3.5.1 I think it is, which supports Windows 7. Now the communication doesn't work. I've got him to run the troubleshooting wizard for ni serial and everything seems fine.
The client says he's tried a cheap usb to serial converter in place of the NI product and everything has worked. Maybe its got something to do with the configuring of the com ports when the device is plugged in?
Thanks,
Jevon

Hello Jevon,
Here is a few other things I would try. First does the Windows 7 machine see the COM port in the device manager? If it does, I would make sure to see if MAX sees the device on the customers machine. From MAX you can test the connection with it by using the NI-Serial communicator. I have copied the steps to do this from the manual below.
Launch MAX.
Expand the My System directory by clicking the
+ next to the folder.
Expand the Devices and Interfaces directory by clicking the
+ next to the folder.
Select your serial interface and expand it to see its ports by clicking the
+ next to its name.
Right-click on the serial port you want to use and select
Communicate with Instrument. This launches the NI-Serial
Communicator.
Depending on the result of this test, the problem could be with the serial converter or the program communicating with this device. There is a Knowledgebase that contains a lot of different ways to debug these problems and the URL is below.

Usb to serial converter console access on aironet 1131

I am having difficulty accessing the console port utilizing a usb to serial converter. My settings are 9600, 8,n,1 and flow control is none.
The converter works if I use it for switches and router but fails on the aironet.
I can access the aironet if I go directly to the serial port.

Hi,
I haven't seen this problem except when I chose the incorrect COM port in my terminal emulator. Otherwise, usb-to-serial cables haven't presented any issues with Aironet equipment.
Sorry I couldn't help further. Maybe someone else has seen this issue.

Parallel to SPI converter

I'm looking for Parallel to SPI converter component in order to convert SPI from DAC and ADC after opto-couplers to 60x-bus of MPC875.
If you know device that can fit my needs please advice me

Hi!
I changed my mind and I would like to use some of your devices to connect my ISM transceiver to the PC.
The interfaces I need are:
-An SPI that works as slave (my device is an SPI master, it generates its own clock signal)
-6 GPIO
I saw that you have the USB8451 but it works alwasy as a master, so i think i can not use it...
Thank you so much!!

Why won't my USB to Coax converter work? No output

I'm trying to use a USB to Coax converter with my iMac. It's detected just fine but when I try to play any audio in iTunes it flat out won't tick past 0:00. It's like iTunes doesn't recognize it as an output.
The device is an Audio-gd Digital Interface and I want to use it because the USB section of my Marantz SA8004 is awful. I know it's probably a quick fix but I'm at a loss.

Is this a USB hard drive or a USB thumb drive?
If hard drive is it one of the USB powered drives, IE No AC Adapter to supply power to the drive?

Are there any usb to parallel converter cables that work with iMac 10.6?

Have a Brother HL-5340D with damaged USB port, can I connect with a usb to parallel converter cable and have it work?

If you try to tweak the dock with third party software, that will corrupt the Dock preferences. Better to leave well enough alone.

None of the stores seem to have a spare for the iphone USB to Lightining converter cable, why is that????

The charger for my iphone5 is lost and I am trying to find a replacement. None of the stores have a stock of the original apple USB to lightning converter cables, most of them dont have it at all or have a third party cable from Gecko or some other brand. Cant see why they are not stocking original apple products despite them being premium resellers of Apple. Is apple even aware of all of this.

We're users here Vivek, not Apple. Asking your question here is pointless. We don't speak for Apple and would have no more idea than you do as to why these are out of stock.
Do you have a technical support issue?

1 more time: I installed Samsung 840EVO SSD and tried to clone the OEM drive to it. Disk Utility shows all files landed in the new SSD thru the USB to SATA converter cable yet my Mac won't boot. Why's that?

The question is why won't my Mac boot with the new 840EVO SSD that I thought I'd successfully cloned all contents from the OEM hard drive by using a USB to SATA converter cable. Disk Utility seemed to indicate the SSD had captured everything from the OEM drive. Note the OEM had 2 partitions to run Parallels Windows XP

XP is not supported externally or if you install Mavericks, and Microsoft is trying their hardest t o get people off that old tin can, rightly so.
Usually Carbon Copy Cloner will. Usally. DU is not really meant to and you had 4 partitions before.
This forum is not for MacBook Pro btw.
Cloning with DU or CCC may do a perfect job but not be bootable if t he interface or case is not.
The EVO is capable of 500MB/sec so even your mid-2010 MBP is not going to get the top performance but should be better once you swap it out than what you were using.

USB-8451 SPI

I have a an ADC chip want to control/acquire data using USB-8451 SPI/I2C module.
I have setupped initial SPI settings (clock edge, polarity, speed etc).
If i passed SPI command 3F; the ADC will output data continously...
How can i read this data continously in LV8.5?
how does the program looks like?
I tried while loop. but in while loop I am continuously sending commands isnt it?.
what is the best way to do?
can some one help me on this?

SPI Converter Selection

Hi All,
We are developing an application in LabVIEW to test the DUT through the SPI interface.
The DUT has the two SPI interface.
One SPI interface is used for sending the request command from LabVIEW application (PC COM port or USB) to DUT (SPI BUS). By this time LabVIEW act as Master and DUT act as a Slave. For the request communication clock is generated from the Master. Slave use that clock for data transmission to DUT.
Another SPI interface is used for sending the response command from DUT (SPI Bus) to LabVIEW application (PC COM or USB). By this time DUT act as Master and LabVIEW application act as a Slave. For the response communication clock is generated from the Master (Clock rate is 18 MHz). Slave use that clock for data reception.
Here I need a converter for converting the COM or USB signals to SPI signals. Please let me know which converter is best suitable for this application.
Thanks and Regards,
Bharathi Thiruppathi
