XBee playing "The Imperial March" using a buzzer

In this sample we show how to play a tune using a buzzer and the PWM interface of the Digi Programmable XBee module.

Here a video with the result:

If you can try the sample, here is the source code: LINK

For this sample we are using the PWM API that provides the SDK delivered with the Digi Programmable XBee:

Pulse-Width Modulation (PWM)

Functions
int	pwm_config (xpin_t pin, bool_t enable, uint32_t ton, uint32_t period)
	Function that configures the settings of the Pulse-Width-Modulation module.
int	pwm_enable (xpin_t pin, bool_t enable)
	Function that enables/disables the Pulse-Width-Modulation.
uint32_t	pwm_get_period (xpin_t pin)
	Function that returns the current period for the Pulse-Width-Modulation component.
uint32_t	pwm_get_ton (xpin_t pin)
	Function that returns the current positive semiperiod for the Pulse-Width-Modulation component.
uint32_t	pwm_set_ton (xpin_t pin, uint32_t ton)
	Function that changes the positive pulse-width of the Pulse-Width-Modulation component.
