#define LED_TC   TCE0

Timer/counter to use for LED output.

This is the timer/counter module to use for outputting a signal indicating the peripheral clock frequency of the device. Compare/capture channel A of the timer/counter is used in this example, corresponding to pin 0 on its associated port.

Note

This TC is on port E, which is connected to the onboard LEDs.

#define NEXT_BUTTON   SW0_PIN

Pin to use for button input.

This is the active low pin to use for user input.

Note

The pin is assumed to be configured by the board initialization.

This is the onboard push button next to LED0.
