This application is designed to integrate custom menus of VIA into Vial. By writing the definitions for VIA's custom UI in vial.json, various menus can be displayed.
Currently, this application supports only the button, toggle, range, dropdown, and color UI elements. It does not support the keycode UI element.
To use this with Vial firmware, implement via_custom_value_command_kb as per the VIA documentation. Additionally, implement raw_hid_receive_kb as shown below.
void raw_hid_receive_kb(uint8_t *data, uint8_t length) {
uint8_t *command_id = &(data[0]);
// Due to an older version of via.c in Vial that does not support
// id_custom_set/get_value, we use id_handled to invoke via_custom_value_command_kb.
if (*command_id == id_unhandled) {
via_custom_value_command_kb(&data[1], length - 1);
}
}
