Hi All,

I write those code. But I can't get interrupt when GPIO has been trigger.

How can I do?

// Set Interrupt Type for GPIO

GPIOIntTypeSet(GPIOA0_BASE, GPIO_PIN_0, GPIO_BOTH_EDGES);

osi_InterruptRegister(INT_GPIOA0,(P_OSI_INTR_ENTRY)GPIOA0_Interrupt, INT_PRIORITY_LVL_1);

// Enable Interrupt

GPIOIntEnable(GPIOA0_BASE,GPIO_INT_PIN_0);

Are you using TI-RTOS or FreeRTOS or neither? If you are using TI-RTOS, you can run the GPIO Interrupt example?

Hi ToddMullanix ,

1.My project based on wlan_station example. The wlan_station example is a TI-RTOS example.

2.At first, I follow Interrupt example step. But run long time ,the system will crash. The Interrupt example is a non-os example.

// Set Interrupt Type for GPIO

GPIOIntTypeSet(GPIOA0_BASE, GPIO_PIN_0, GPIO_BOTH_EDGES);

GPIOIntRegister(GPIOA0_BASE,GPIOA0_Interrupt);

// Enable Interrupt

GPIOIntEnable(GPIOA0_BASE,GPIO_INT_PIN_0);

That's not the TI-RTOS GPIO Interrupt example. Go into Resource Explorer Classic and navigate to TI-RTOS->Examples-><board>/Drivers->GPIO (I think this is the path ... I'm not on my work laptop, so I'm guessing a bit.
