# Let's Split Flashing (More information at `qmk_firmware/layouts/community/ortho_3x10/wanleg/readme.md`) ## Make the QMK DFU .hex `make lets_split/rev2:wanleg:production dfu=qmk` ## Burning EEPROM settings and Firmware Navigate to the directory with your .hex file and the `eeprom-lefthand.eep` and `eeprom-righthand.eep` files in it. **Burn Left Side With QMK DFU and Firmware** `avrdude -b 19200 -c avrisp -p m32u4 -v -e -U lock:w:0x3F:m -U efuse:w:0xC3:m -U hfuse:w:0xD9:m -U lfuse:w:0x5E:m -U eeprom:w:eeprom-lefthand.eep -P comPORT -U flash:w:YOUR_production.hex:a` **Burn Right Side With QMK DFU and Firmware** `avrdude -b 19200 -c avrisp -p m32u4 -v -e -U lock:w:0x3F:m -U efuse:w:0xC3:m -U hfuse:w:0xD9:m -U lfuse:w:0x5E:m -U eeprom:w:eeprom-righthand.eep -P comPORT -U flash:w:YOUR_production.hex:a` Change `comPORT` to whatever port is used by the Arduino (e.g. `com11` in Windows or `/dev/ttyACM0` in Linux). Use Device Manager in Windows to find the port being used. Use `ls /dev/tty*` in Linux. Change `YOUR_production.hex` to whatever you've created in the previous step. ## Using QMK DFU Once QMK DFU is burned to your ProMicro, you can then flash subsequent hex files with `make lets_split/rev2:<keymap>:dfu dfu=qmk` The `dfu=qmk` conditional will set `BOOTLOADER = qmk-dfu` instead of `BOOTLOADER = caterina` # Let's Split LEDs In `qmk_firmware/keyboards/lets_split/rev2/rev2.c`, replace contents with ``` #include "lets_split.h" #ifdef SSD1306OLED void led_set_kb(uint8_t usb_led) { // put your keyboard LED indicator (ex: Caps Lock LED) toggling code here led_set_user(usb_led); } #endif void matrix_init_kb(void) { // // green led on // DDRD |= (1<<5); // PORTD &= ~(1<<5); // // orange led on // DDRB |= (1<<0); // PORTB &= ~(1<<0); //turn off LEDs on ProMicro DDRD &= ~(1<<5); PORTD &= ~(1<<5); DDRB &= ~(1<<0); PORTB &= ~(1<<0); matrix_init_user(); }; ``` to turn off LEDs
