pico_arduino::PicoPWMNano Class Reference

Basic PWM API based on the input and output in nano seconds The Raspberry Pico has 8 controllable PWM slices with each 2 channels, so we can control up to 16 pwm devices at the same time! This is Simple Basic PWM API where we specifiy the periods and duty cyle in Nanoseconds. More...

Public Member Functions
	PicoPWMNano (uint64_t periodNanoSeconds)
	Constructor: Defines the length of a full cycle in nanoseconds (mio of seconds)
void	begin (pin_size_t gpio, uint64_t initialDutyCyleNanoSeconds=0, PinMode pinMode=OUTPUT)
	setup the pin mode only if necessary
void	end (pin_size_t gpio)
	sets the output pins to low
float	frequency ()
	converts the PWM period to hz for the PWM output
uint64_t	measureDutyCycle (uint gpio)
	measures the duty cycle in nanoseconds - only the PWM B pins can be used as inputs!
float	measureDutyCyclePercent (uint gpio)
	provides the duty cycle in percent
uint64_t	period ()
	provides the full cycle period in nanoseconds
void	setDutyCycle (pin_size_t gpio, uint64_t dutyCyleNanoSeconds)
	Defines the active period is nanoseconds.
