Question
Hi, I´m using STM8S0003F. I have 2 pins at PORT A (PA1 and PA3 that are programmed to generate an interrupt when any signal FALL_ONLY. During the interrupt routine, how can I know which pin generate this interrupt? Thank you Andre
INTERRUPT_HANDLER(EXTI_PORTA_IRQHandler, 3)
{
/* In order to detect unexpected events during development,
it is recommended to set a breakpoint on the following instruction.
*/
if(!GPIO_ReadInputPin(RUIDO_PASS_Port, RUIDO_PASS_Pin))
{
Tmr10msLeRuido1 = 20;
}
if(!GPIO_ReadInputPin(RUIDO_MOT_Port, RUIDO_MOT_Pin))
{
Tmr10msLeRuido0 = 20;
}
}
