GPIO Interrupt Detection

Hi Dialog,

Problem Statement
- Register a GPIO interrupt/ISR using GPIO_RegisterCallback( ) and detect if the short press and long press on the button when the system is up and running.

What I tried

• I'm using the SW_2 (P0_6) for this functionality since the SW_3 is currently been used for wkupct_register_callback( ) that initialises the BLE advertisement.
• I was able to register the GPIO interrupt callback by the following method

空白register_button_isr(空白)
{
NVIC_DisableIRQ(GPIO1_IRQn);
// set isr callback for button pressed interrupt
GPIO_RegisterCallback(GPIO1_IRQn, push_button_callback);
// Push Button input
GPIO_EnableIRQ(GPIO_PORT_0, GPIO_PIN_6, GPIO1_IRQn, true, true, 0);
}

• I've configured the GPIO under the set_pad_functions( ) and reserved the GPIO in GPIO_reservations( ).
• Turn the LED on the DA14583_ProDK if the SW_2 is pressed, and when pressed again, turn off the LED.

Observation

• When the system is in active mode, i.e. broadcasting BLE advertisement packets, the ISR is not generated by the SW_2 pin
• If I follow the same process by modifying the Blinky example, everything just works perfect

Attached below (ble_examples.zip) is the file containing the modified Blinky example and the new file that I added in the ble_all_in_one application

Looking towards a positive response.

Thanking you in advance
