# QMK-based firmware for Fujitsu N860-2500-T111 keyboard
Fujitsu N860-2500-T111 keyboard conversion project: direct connection of Black Pill to the matrix.
* Keyboard Maintainer: [DmNosachev](https://github.com/DmNosachev)
* Hardware Supported: [Fujitsu N860-2500-T111](https://deskthority.net/viewtopic.php?t=17087), Black Pill STM32F103C8T6 MCU board. Alternatively you can use any MCU which is supported by QMK and has 22 or more IO pins: Arduino Micro, Teensy 2.0, Teensy 2.0++, Blue Pill, etc.
* Thanks to Deskthority user *OldIsNew* for the matrix decoding.
Make example for this keyboard (after setting up your build environment):
make handwired/t111:default

# Modding
## Matrix
Fujitsu N860-2500-T111 has 14x8 matrix. It's ghost-free thanks to the diodes.
Rows (0-7) and columns (0-D):

1. Desolder all ICs, capacitors and resistors.
1. Solder 4-pin SWD header to Black Pill.
2. Burn [STM32duino bootloader](https://github.com/rogerclarkmelbourne/STM32duino-bootloader/blob/master/bootloader_only_binaries/generic_boot20_pb12.bin) to Black Pill.
3. Compile and flash the firmware: `make handwired/t111:default:flash`
4. Connect rows and columns to the corresponding pins of the Black Pill.
