Function Documentation

PWM_Init()

void PWM_Init	(	const PwmModuleAddress	moduleBaseAddress,
		const PwmOutChannel	channel,
		const uint32_t	frequency,
		const bool	isOutputInverted,
		const uint16_t	initialDutyCycle
	)

Initializes the PWM output according to the specified parameters.

Parameters

moduleBaseAddress
channel
frequency
isOutputInverted
initialDutyCycle

PWM_SetDutyCycle()

void PWM_SetDutyCycle	(	const PwmModuleAddress	moduleBaseAddress,
		const PwmOutChannel	channel,
		uint16_t	dutyCycle
	)

Sets the duty cycle for a specific channel.

Parameters

moduleBaseAddress
channel
dutyCycle	- 0 means fully closed, 5000 means fully open. If > 5000, it's limited to 5000
