This is a port of the original M0110 converter from TMK to QMK. The original converter was designed to work with ATmega32U2 and ATmega32U4 based microcontrollers to convert Apple M0110/M0110A keyboards and M0120 numpads to USB. This port has been tested to be compatible with the Adafruit Feather 32U4 BLE.
Simply add BLUETOOTH = AdafruitBLE
to your rules.mk
file. This enables code specifically for the Adafruit Feather 32U4 BLE. If enabled, the device will use the PRODUCT
value from config.h
for the device name displayed by the Feather on host devices. You can simply change these values to change the device name.
This port utilizes the same pins that the TMK converter used. PD1
is used for CLOCK
and PD0
is used for the DATA
from the keyboard. These pins can be changed in config.h
.
Hardware
You can buy preassembled TMK converter or make yourown with AVR dev board like PJRC Teensy.
Port of the MCU
PD1
is assigned toCLOCK
line andPD0
toDATA
by default, you can change pin configuration with editingconfig.h
.4P4C phone handset cable
Note that original cable used with Mac is straight while phone handset cable is crossover.

Socket Pinout
Pull-up Resistor
You may need pull-up resistors on signal lines(
CLOCK
,DATA
) in particular when you have long or coiled cable. 1k-10k Ohm will be OK >for this purpose. In that case the converter may not read signal from keyboard correctly without pull-up resistors.
