void pwmDisableAllLeds

(

void

)

This disables the output of the all pwm pins.

Returns

void

void pwmDisableSingle

(

uint32

pin_name)

This disables the output of the given pwm pins. The input argument should be any logical OR of valid PWM BIT pin names, e.g. RED_LED_PWM_BIT.

Parameters

pin_name

- name of pins wanted to change

Returns

void

void pwmEnableAllLeds

(

void

)

Enables the pwm output for all 3 LEDs.

Returns

void

void pwmEnableSingle

(

uint32

pin_name)

This enables the output of the given pwm pin. The input argument should be the name of the function of a given PWM pin, i.e. RED_LED.

Parameters

pin_name

- name of pins wanted to change

Returns

void

void pwmInitializeBeacon

(

void

)

Sets up the PWM pins for the IR beacon PWM control.

Returns

voids

void pwmInitializeLed

(

void

)

Initializes the PWM pins. Configures the RGB LEDs to be countdown PWM pins. They are flashed once.

Returns

void

void pwmSetDuty	(	uint32	pwm_target,
		uint16	duty
	)

Brief: Sets the duty cycle length for one pin period is the current length of the entire PWM period

Parameters

pwm_target	is the pin which needs to have its duty cycle changed. In the IR beacon it is colors
duty	is the duty cycle for when the pin is ON, and can range from 0 to 100

Returns

void

void pwmSetDutyAllLeds

(

uint16

duty)

Changes the duty cycle for all of the LED PWM pins period is the current length of the entire PWM period.

Parameters

duty	is the length of the new duty cycle and should be 0-100

Returns

void
