Make example for this keyboard (after setting up your build environment):
The Pro Micro variant runs at 8MHz, hence the following line in
F_CPU ?= 8000000
If the firmware doesn’t work, try changing that line to
F_CPU ?= 16000000
or override the
F_CPU variable in the
rules.mk of your keymap.
There are two options to get a converter: You can buy one from Hasu or build one yourself.
You can buy a fully assembled converter from me here: https://geekhack.org/index.php?topic=69169.0
Buying Arduino Leonardo and USB Host Shield 2.0(from Circuit@home) will be better, you won’t need even soldering iron. http://arduino.cc/en/Main/ArduinoBoardLeonardo https://www.circuitsathome.com/arduino_usb_host_shield_projects/
Also Pro Micro 3.3V(not Mini) or Teensy with mini host shield will work with some fixes on signal/power routing. Build guide https://www.circuitsathome.com/arduino_usb_host_shield_projects/ https://www.sparkfun.com/products/12587 https://www.pjrc.com/teensy/td_libs_USBHostShield.html
Only supports ‘HID Boot protocol’. Note that the converter can host only USB “boot protocol” keyboard(6KRO), not NKRO, it is possible to support NKRO keyboard but you will need to write HID report parser for that. Every NKRO keyboard can have different HID report and it is difficult to support all kind of NKRO keyboards in the market.
