WebGPIO events can be mapped to an interrupt and assigned to a callback function. The callback function needs to be first registered and then the event needs to be enabled. The following snippet initializes GPIO pin P0_0 as an input pin. It registers a callback function and enables detection of a falling edge event to trigger the callback. Note WebUNUSED(GPIO_Pin); /* NOTE: This function should not be modified, when the callback is needed, the HAL_GPIO_EXTI_Callback could be implemented in the user file. */. } The STM32G0 HAL splits the EXTI into two type ( rising and falling ).

WebThe board used are: NUCLEO-l4p5zg: Transmitter (TX); STM32MP157A-DK1: Receiver (RX); The TX lowers the pin to start the communication. When the pin is lowed an interrupt is triggered and the RX enables the reception. (TX lowers the pin PG15 that is the pin PG8 for the RX) The interrupt triggers multiple times instead of once.
