// This is a test harness for VIA custom UI.
|
|
//
|
|
// It handles channel IDs 0-7, value IDs 0-7.
|
|
//
|
|
// It's useful for testing custom UI on a PCB without compiling in
|
|
// features, especially features that will cause firmware to freeze
|
|
// if the PCB doesn't have support.
|
|
//
|
|
// To use:
|
|
// - add `SRC = keyboards/wilba_tech/via_test.c` to rules.mk
|
|
// - add `#define VIA_EEPROM_CUSTOM_CONFIG_SIZE 128` to config.h
|
|
// (or change to match CHANNELS*VALUES*2)
