USB I2C HID device?

Postby T-5 » Tue Apr 13, 2021 7:14 pm

Hi,

Sorry if this topic has already been discussed but i was not able to find anything, partly due to the fact that "usb i2c hid" all are words that will not produce any search results in this forum.

I have a XUF512 (Exact designation: XS2-UnA-512-FB236) running with UAC2 (12 channel i2s out, 6 channel i2s in).

What I'd like to add is a USB HID device with functionality similar to the CP2112 (https://www.silabs.com/interface/usb-br ... ice.cp2112) that allows the XMOS chip to act as an USB to I2C bridge.

Has this done before, are there any examples around?

Thanks in advance and best regards,
Jürgen

You can study the following appnote on HID use and review the I2C example inside this document:
