Labview drivers for the trinamic USB-2-X ?

[Sam Hakosem]

We would like to operate our home made devices using the I^2C interface of the Trinamic USB-2-X module. (We have bought it with the TMC222-eval kit package).

Did any body developed drivers for this module?

Thanks.

Howdy Sam,

Unfortunately I have never seen any drivers for that device, however you are free to submit a request to have some developed or develop on yourself through our instrument driver network.  Additionally, NI sells a I2C/SPI interface, the NI USB-8451, that might be useful for communication.  Good luck, post back if you'd like more info!

Thanks Chris,

I tried to developed one, so far with no success. I followed the instructions given in the USB Instrument Control Tutorial to create a NI-VISA “.inf” file. The Trinamic USB converter is “RAW” and it seems like I succeeded.

The Trinamic USB-2-X converter has a communication protocol  that I tried to implement. However, I could not put it to work, yet. While communicating with the converter I do not get any error message, but also could not get an acknowledgement either.

I borrowed an 8451 and indeed it works like a charm. It seems that I will have give up on the Trinamic and spend the money to buy the 8451.

Sincerely,
Sam
