help overriding pins config

I have nice_nano_v2 with damaged GPIO 5. I rewired row 2 of corne to use pin 0 (by adding wire between pins) and modified corne shield definition in zmk source code file "zmk/app/boards/shields/corne/corne_left.overlay" (I build locally). How can I achieve same effect, but through user-config?

To remap pins via user config, create a zmk.conf file in your config directory. Add these lines, replacing the pin numbers with your desired configuration:

CONFIG_ZMK_KEYBOARD_NAME="corne"
CONFIG_BT_CTLR_TX_PWR_PLUS_8=y

&kscan0 {
  col-gpios
   = <&pro_micro 2 GPIO_NUM GPIO_ACTIVE>,
     <&pro_micro 3 GPIO_NUM GPIO_ACTIVE>,
     <&pro_micro 4 GPIO_NUM GPIO_ACTIVE>,
     <&pro_micro 15 GPIO_NUM GPIO_ACTIVE>,
     <&pro_micro 18 GPIO_NUM GPIO_ACTIVE>,
     <&pro_micro 19 GPIO_NUM GPIO_ACTIVE>;
  row-gpios
   = <&pro_micro 29 GPIO_NUM GPIO_ACTIVE>,
     <&pro_micro 28 GPIO_NUM GPIO_ACTIVE>,
     <&pro_micro 27 GPIO_NUM GPIO_ACTIVE>,
     <&pro_micro 26 GPIO_NUM GPIO_ACTIVE>;
};

CONFIG_ZMK_KEYBOARD_NAME="corne"
CONFIG_BT_CTLR_TX_PWR_PLUS_8=y

&kscan0 {
  col-gpios
   = <&pro_micro 2 GPIO_NUM GPIO_ACTIVE>,
     <&pro_micro 3 GPIO_NUM GPIO_ACTIVE>,
     <&pro_micro 4 GPIO_NUM GPIO_ACTIVE>,
     <&pro_micro 15 GPIO_NUM GPIO_ACTIVE>,
     <&pro_micro 18 GPIO_NUM GPIO_ACTIVE>,
     <&pro_micro 19 GPIO_NUM GPIO_ACTIVE>;
  row-gpios
   = <&pro_micro 29 GPIO_NUM GPIO_ACTIVE>,
     <&pro_micro 28 GPIO_NUM GPIO_ACTIVE>,
     <&pro_micro 27 GPIO_NUM GPIO_ACTIVE>,
     <&pro_micro 26 GPIO_NUM GPIO_ACTIVE>;
};

Replace GPIO_NUM with the new pin number for row 2. Let me know if you need further help!

I need this mod only for left half

Mystery•2w ago

you can have _left config that only applies the left board. see mine: https://github.com/DarrenVictoriano/zmk-config/tree/master/config

This is my custom Corne keyboard layout with nice!nano v2 + nice!view + seed xiao as dongle - DarrenVictoriano/zmk-config

Mystery•2w ago

When using a split keyboard, you can use a single file without the _left or _right suffix to configure both sides. For example, corne.conf and corne.keymap will apply to both corne_left and corne_right. If a shared config file exists, any left or right files will be ignored.

Configuration Overview | ZMK Firmware

ZMK has many configuration settings that can be changed to change the behavior of your keyboard. They are set in either Kconfig or Devicetree files.
