First, an intro before my question ... I am using the TWR-K22F120M tower board to develop a USB device. Using the SDK for that board including the USB stack and FreeRTOS, I have successfully tested the example code for the generic HID with FreeRTOS ("dev_hid_generic_freertos"). This required downloading and modifying code from codeproject.com per the readme.pdf (attached) in the example code folder. Here is the link:
Follow the readme instructions EXACTLY and it will work. I initially compiled the C# program for "all processors" and it would compile and run, but it would not connect to the device and echo data. NOTE - there are code modifications required and defined in the readme. Here is what the running program looks like except that I modified the VID/PID and default send data:
QUESTION: Being brand new to the USB game, I assume the VID and PID are hard-coded somewhere in the example code. I verified that the VID is for NXP. Since I'm a little slower than the other kids, I could not find where this is. We have our own VID and PID block reserved, so I would like to put it in the code. Does anyone know where VID and PID are defined in this project?
