This repository contains the firmware I used to flash my Arduino Pro Micro that was handsoldered to 60TKL Layout keyboard.
I used QMK configurator to plan the layout: QMK Configurator
Then the now deprecated Keyboard Firmware Builder to get an outline for the firmware: Keyboard Firmware Builder
Then I downloaded a version of QMK MSYS and created a new keyboard forantti60, adjusted the keymap and keyboard.json to my needs and compiled: QMK MSYS
I used command
qmk compile -kb forantti60 -km default -c
to compile, with -c added for a clean compilation because of the compiler ignoring changes to .json files.
Then I used QMK toolbox to flash the firmware on the Arduino micro QMK Toolbox
The pinout in the Arduino Pro Micro was soldered as follows:
Columns from 0 to 14: "C6", "D7", "E6", "B4", "B5", "B6", "B2", "B3", "B1", "F7", "F6", "F5", "F4", "B0", "D5"
Rows from 0 to 4: "D0", "D1", "D2", "D3", "D4"
with 0,0 at the left top.
