Hello Dialog,
Can I know the GPIO pin header 'X' in GPIOx and IRQ 'n' mapping?
How to configure different port pins for GPIO interrupts?
Is it per port 'X' - 5(n) configurable interrupts?
Thanks

Hi rajucoolsuraj,
If you would like to configure a GPIO interrupt it doesn’t matter which GPIOx_IRQn (x= 0,1,2,3,4) you will select. Just chose one of them, that's no problem. If you use more than one GPIO interrupt, in the inputs of GPIO_EnableIRQ() pass different types of GPIOx_IRQn. Suppose that you would like to configure the GPIO_PORT_2 , GPIO_PIN_1 as a high level triggered GPIO interrupt with 2ms denouncing time. You should call the GPIO_EnableIRQ() as follow:
GPIO_EnableIRQ(GPIO_PORT_2, GPIO_PIN_1, GPIO0_IRQn, false, false, 2);
Thanks, PM_Dialog
