Well, libhidapi support meanwhile entered the tree already,
as part of EDBG support.

I'd ask for the following things:

  • please file new parts in in a separate patch file
  • please add documentation additions for the new programmer (ideally, both avrdude.1 and doc/avrdude.texi, but I could easily craft one of those myself based on the other one)

This implements support for our open hardware "mcprog" interface. EAGLE files available at:

mcprog uses the MCP2210 USB-to-SPI interface.
This code was successfully tested on Linux and MAC.

The patch started as a copy of the pickit2 code already shipped with avrdude, but as the libusb backend seems to be dysfunctional on MAC for quite some time, I replaced libusb by libhidapi.

Therefore, this patch also brings support for libhidapi to avrdude. It's probably a good idea to use libhidapi instead of libusb for other programmers, that use the USB HID protocol.
