USB-8451

Hi, is there any standard GUI to test USB-8451 is working or not?

You can open NI MAX, select your device, and open a "Test Panel" if the option exists.

computer detects the device, but don't see any option to open Test panel.

 

is there any option to find test panel?

if computer detects the device, that means device is GOOD?

Not necessarily, you should be able to run a self-test on the device. If you don't see the self-test or test panels options then you probably need to update / install NI DAQmx drivers.

The USB-845x devices are NOT DAQmx.  They have their own driver because they are for something completely different than DAQ (SPI and I2C communication).  And there is no built-in test panel that I have been able to find.  I don't blame NI for this since there are A LOT of different ways I2C is even interpreted (registers or no registers, 16-bit vs. 8-bit, etc.)

Thanks Crossrulz,

I have one question instead of USB-8451, what other devices I can use for SPI and I2C communication.

 

Thanks.

Hi pavan,

 

you can use the NI8452 instead.

 

Or a simple Arduino will do the SPI/I²C communication while communicating with LabVIEW using its virtual COM port…

Best regards,

I have done some messing around with a NXP SC18IM700 to do I2C using a serial port.  It uses a TTL UART, so some additional circuitry is needed to convert the RS-232 port on your computer to the TTL levels.

 

But I will probably go with an Arduino or RaspberryPi next time I might need one of these.  It will be easier than getting a custom board built.

is there any particular board you can suggest me from Arduino group for SPI/I2C communication ?
