Hi, I am using Mesh v4.2.0 and nRF52840 light_lightness example but instead of button_event_handler, I am using GPIOTE to control the lights.
I want to toggle one LED with one button, say when I press button 1, LED 1 will turn on, and when I press button 1 again, LED 1 will turn off. How do I do that?
This is a part of my code:
//Button 1 Interrupt Handler
void button1_handler(nrf_drv_gpiote_pin_t pin, nrf_gpiote_polarity_t action)
{
nrf_drv_gpiote_out_toggle(BSP_LED_1);
}
int main(void)
{
/*Setup GPIOTE*/
//Call nrf_drv_gpiote_init() to initialize the GPIOTE.
nrf_drv_gpiote_init();
//Create a variable of type nrf_drv_gpiote_out_config_t, and-
//configure a pin to use the GPIOTE TASK_OUT to to toggle the pin state.
nrf_drv_gpiote_out_config_t out_config = GPIOTE_CONFIG_OUT_TASK_TOGGLE(false);
//Call nrf_drv_gpiote_out_init(output pin) to initialize pin13 to be controlled using GPIOTE
nrf_drv_gpiote_out_init(BSP_LED_1, &out_config); //BSP_LED_0 == LED1 == pin13 defined in pca10056.h
//Set a GPIOTE output pin (Turn Off LED1 - Active Low)
nrf_drv_gpiote_out_set(BSP_LED_1);
//Create a variable of type nrf_drv_gpiote_in_config_t, and-
//configure a pin to use GPIOTE EVENT_IN to detect any change on the pin.
nrf_drv_gpiote_in_config_t in_config = GPIOTE_CONFIG_IN_SENSE_TOGGLE(true);
in_config.pull = NRF_GPIO_PIN_PULLUP; //configure pull up resister.
nrf_drv_gpiote_in_init(BUTTON_1, &in_config, button1_handler);
nrf_drv_gpiote_in_init(BUTTON_2, &in_config, button2_handler);
nrf_drv_gpiote_in_init(BUTTON_3, &in_config, button3_handler);
//Enable events and its interrupts.
nrf_drv_gpiote_in_event_enable(BUTTON_1, true);
nrf_drv_gpiote_in_event_enable(BUTTON_2, true);
nrf_drv_gpiote_in_event_enable(BUTTON_3, true);
initialize();
start();
for (;;)
{
(void)sd_app_evt_wait();
}
}
*Don't mind button2 and button3.
