Flashing

QMK Toolbox supports the following bootloaders:

And the following ISP flashers:

  • AVRISP (Arduino ISP)
  • USBasp (AVR ISP)
  • USBTiny (AVR Pocket)

If there's an interest in any others, they can be added if their commands are known.

HID Console

The Toolbox also listens to HID messages on usage page 0xFF31 and usage 0x0074, compatible with PJRC's hid_listen.

If you have CONSOLE_ENABLE = yes in your keyboard's rules.mk, you can print messages with xprintf(), useful for debugging:
