Cradio

Cradio is a firmware for a few 34 key keyboards, including Cradio, Hypergolic and Sweep.

Pin arrangement

Some revisions of the aforementioned PCBs have slightly different pin arrangements compared to what's defined in cradio.dtsi. If you need to swap a few keys for your particular PCB, you can easily reorder the input-gpio definition in your own keymap file (i.e. in zmk-config/config/cradio.keymap):

/* Adjusted Cradio pin arrangement */
/* The position of Q and B keys have been swapped */
&kscan0 {
	input-gpios
	= <&pro_micro_d  6 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
	, <&pro_micro_a  0 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
	, <&pro_micro_a  1 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
	, <&pro_micro_a  2 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
	, <&pro_micro_a  3 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
	, <&pro_micro_d 15 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
	, <&pro_micro_d 14 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
	, <&pro_micro_d 16 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
	, <&pro_micro_d 10 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
	, <&pro_micro_d  1 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
	, <&pro_micro_d  2 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
	, <&pro_micro_d  3 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
	, <&pro_micro_d  4 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
	, <&pro_micro_d  5 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
	, <&pro_micro_d  7 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
	, <&pro_micro_d  8 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
	, <&pro_micro_d  9 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
	;
