From 4d81b10ba7047a4dbd63cfe33ac879ecf437e108 Mon Sep 17 00:00:00 2001 From: Mega Mind <68985133+megamind4089@users.noreply.github.com> Date: Tue, 6 Oct 2020 15:52:21 +0800 Subject: Added driver to control the external power output This PR adds support to control the external power output from controllers like nice!nano, nRFMicro etc I have implemented based on my understanding of Pete suggestion on this feature. Testing done: Tested by enabling and disabling the ext_power from application and verified Verified the application does not crash with boards that does not have ext_power support Note: I did not test this in nice!nano since I don't have the boards. Will get help from others once the behavior PR is up Next Steps: Create a behavior PR to control enable/disable ext_power --- app/src/main.c | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'app/src/main.c') diff --git a/app/src/main.c b/app/src/main.c index dca923e..0551356 100644 --- a/app/src/main.c +++ b/app/src/main.c @@ -15,16 +15,25 @@ LOG_MODULE_REGISTER(zmk, CONFIG_ZMK_LOG_LEVEL); #include #include #include +#include #define ZMK_KSCAN_DEV DT_LABEL(ZMK_MATRIX_NODE_ID) void main(void) { + struct device *ext_power; LOG_INF("Welcome to ZMK!\n"); if (zmk_kscan_init(ZMK_KSCAN_DEV) != 0) { return; } + // Enable the external VCC output + ext_power = device_get_binding("EXT_POWER"); + if (ext_power != NULL) { + const struct ext_power_api *ext_power_api = ext_power->driver_api; + ext_power_api->enable(ext_power); + } + #ifdef CONFIG_ZMK_DISPLAY zmk_display_init(); -- cgit v1.2.3
