HID is one step closer on the open source USB stack for PIC microcontrollers

Posted on Tuesday, March 6th, 2012 in open source, USB by DP

Dolabra took up the task to add support for the HID class to Hoken and JTR’s open source USB stack. Up till now it only supported the CDC class, and HID is still a long way away, but progress has been made.

Yeah! a small victory. I got a set of descriptors that enumerate! The biggest problem that I had is that the HID driver sends a GET_DESCRIPTOR request as at standard request to the interface. The stack isn’t really set up for that and it took me quite awhile to figure out that is what was going on.

If you’d like to help out in designing a true open source USB stack, head to the forum.

    super nice. HID should be a way smaller footprint then CDC .. kudos

    Most of things that need PC connectivity and don’t need high speeds, HID is undoubtedly the best choice ;-)

    No need for driver of inf files, and you can find HID libs for linux/mac/win that easy the job in the PC side, better is difficult.
