Example Usage

Run the example.

1. Board_LED0 is toggled by pushing Board_BUTTON0.

2. Board_LED1 is toggled by pushing Board_BUTTON1.

• Each key's interrupt is configured for a falling edge of the pulse. A small delay has been added to provide button de-bounce logic.

Application Design Details

• The pinCallbackFxn function is defined in the pinInterrupt.c file. This function is called in the context of the pin interrupt (Hwi).

For IAR users using any SensorTag(STK) Board, the XDS110 debugger must be selected with the 4-wire JTAG connection within your projects' debugger configuration.
