1. This sample demonstrates 28035 external interrupt configuration and method of use. 28035 a total of three external interrupt, the three outer interruption Interrupt trigger source can be configured for GPIO0- between GPIO31 any one This example, and I will GPIO27 as XINT1 The interruption of the trigger, if key press, a falling edge will trigger into interrupt, in interrupt, we will make the state of D2 Turn over one time. 2. External interrupt XINT can be configured to rising edge trigger, falling edge contact, bilateral trigger (rising edge and falling edge are trigger).
