Running USBD_HID_GENERIC in nRF52832 using a custom USB module (MCP2200)

[Maher Shakir]

Hi,

I am currently using the nRF52832 and I just recently realized that it does not have USB capabilities. I am building a custom board with this chip and I want to use my own UART to USB IC (MCP2200). I see that the nRF52840 has a USB_hid_generic example, am I able to use this example with my chip?

I changed the buttons location in the 10056.h file to match the one in 10040.h file to see if that's the only modification needed to realize the buttons, but it didn't work. So I wonder what other modification needed.

The added USB module was successfully integrated to the nRF52832 and was able to connect to Tx and Rx of the UART and was seen information in PuTTY in another PC, but am not sure if the USB_hid_generic is actually using UART to send the mouse information.

Thanks,

Mahir

As the name suggests, the USB HID example uses the USB  HID profile - it's not a UART!

Then is the HID profile the same in the 10040? or specifically for the 10056? 

So is it possible to use this example on the nRF52832?

That is the USB profile - over the USB link - defined by USB.org.

Highly unlikely - unless the USB implementation in the nRF52840 happens to be a clone of the MCP2200.

Wouldn't it be simpler to just use an nRF52840 ?
