GPIO interrupt problem

al_silantyev — Thu, 07 Nov 2019 13:00:03 GMT

I work whis a castom board based on mk60dn512vlq10. I need to arrange an interrupt on GPIOB. I configured necessary pin to input and interrupt on rising edge, expanded interrupts from port B in int main "EnableIRQ(PORTB_IRQn);" and made an interrupt handler but instead of performing an interrupt when a pulse is applied to the pin, the board freezes. What am I doing wrong?

You may have not entered the interrupt vector correctly or you may not be clearing the interrupt in the hander (by writing the PORTB_ISFR register).

See the following port interrupt video for more details: https://www.youtube.com/watch?v=CubinvMuTwU&list=PLWKlVb_MqDQFZAulrUywU30v869JBYi9Q&index=18

Use the free open source uTasker project as reference for quality code to allow individual interrupt callbacks on each port pin, or use its full project to slash your development time.
