Hello,
I want to control multiple TI DLP NIR NANO EVM spectrometers with the same computer. I know it is not an option in the software provided by TI. But I am trying to controlling the spectrometers with my own Labview code. Can you please tell me if it can be done or no? If yes than how can I can do that because VID and PID of all spectrometers are the same?
Regards,
Moeen.
Hello Moeen,
Yes It can be done but needs some code modification on the TIVA MCU code side.
One suggestion is that Since TIVA MCU has an UID in the registers described in the datasheet as shown below.
You can modify the PID field to be a 16bit checksum of TIVA MCU UID to differentiate each EVM. FYR the said PID is to be modified in the structure data defined in Drivers/usbhandler.c file shown below. Also you can also modify the serial number to UID if needed as an additional check
Once you have modified the code. You should be able to create multiple USB instances and communicate accordingly.
Regards,
Akhil
