Hello,

I just started working with the Cortex and had a question on the USB HID control transfer.

I am working with the ST CUSTOM HID demo application. I am trying to implement GET_REPORT and SET_REPORT functionality to configure my device. I am having difficulty as to where in the code I can insert my routines to process GET and SET_REPORT. Can anyone point me to any example code or project that implements these transfers using ST's USB libraries?

Thanks in advance.

Hey, Thanks for the info. Unfortunately, this USB demo application is the one that I am currently working with. I was surprised to see that none of the demos included support or implement HID control requests such as SET and GET_REPORT. Specifically, I notice that the CUSTOM_HID demo defines FEATURE reports in the HID descriptors, but there is no code that I can see that implements the processing of these packets.

I am assuming that the functions CustomHID_Data_Setup and CustomHID_NoData_Setup in usb_prop.c is where you would parse report requests, but my attempts so far have been unsuccessful. Maybe I am missing something?

Thanks!
