Here's my thought on π Pinout and Schematic - nice!nano
Pinout for nice!nano boards. Note that P0.15 means gpio port 0 pin 15, they can be referenced in zmk when setting column and row pins.
#include <dt-bindings/zmk/matrix_transform.h>
/ {
chosen {
zmk,kscan = &default_kscan;
zmk,matrix_transform = &default_transform;
/delete-property/ zephyr,console;
/delete-property/ zephyr,shell-uart;
};
default_kscan: kscan {
compatible = "zmk,kscan-gpio-matrix";
label = "default_kscan";
diode-direction = "col2row";
col-gpios
= <&gpio0 31 GPIO_ACTIVE_HIGH>
, <&gpio0 29 GPIO_ACTIVE_HIGH>
, <&gpio0 2 GPIO_ACTIVE_HIGH>
;
row-gpios
= <&gpio1 15 (GPIO_ACTIVE_HIGH | GPIO_PULL_DOWN)>
, <&gpio1 13 (GPIO_ACTIVE_HIGH | GPIO_PULL_DOWN)>
, <&gpio1 11 (GPIO_ACTIVE_HIGH | GPIO_PULL_DOWN)>
;
};
default_transform: matrix_transform {
compatible = "zmk,matrix-transform";
columns = <3>;
rows = <3>;
map = <
RC(0,0) RC(0,1) RC(0,2)
RC(1,0) RC(1,1) RC(1,2)
RC(2,0) RC(2,1) RC(2,2)
>;
};
};
