Public Member Functions
void	analogWrite (uint8_t pin, uint16_t value, uint8_t width=8)
	write a PWM value to a PWM-enabled pin More...

uint16_t	analogRead (uint8_t pin)
	read the analog value on an ADC-enabled pin. More...

◆ analogWrite()

void Adafruit_Crickit::analogWrite	(	uint8_t	pin,
		uint16_t	value,
		uint8_t	width = `8`
	)

virtual

write a PWM value to a PWM-enabled pin

Parameters

pin	the number of the pin to write. On the SAMD09 breakout, this corresponds to the number on the silkscreen. on the default seesaw firmware on the SAMD09 breakout, pins 5, 6, and 7 are PWM enabled.
value	the value to write to the pin
width	the width of the value to write. Defaults to 8. If 16 is passed a 16 bit value will be written.

Reimplemented from Adafruit_seesaw.

◆ analogRead()

uint16_t Adafruit_Crickit::analogRead ( uint8_t pin )

virtual

read the analog value on an ADC-enabled pin.

Parameters

pin	the number of the pin to read. On the SAMD09 breakout, this corresponds to the number on the silkscreen. On the default seesaw firmware on the SAMD09 breakout, pins 2, 3, and 4 are ADC-enabled.

Returns: the analog value. This is an integer between 0 and 1023

Reimplemented from Adafruit_seesaw.

◆ setPWMFreq()

void Adafruit_Crickit::setPWMFreq	(	uint8_t	pin,
		uint16_t	freq
	)

virtual

set the PWM frequency of a PWM-enabled pin. Note that on SAMD09, SAMD11 boards the frequency will be mapped to closest match fixed frequencies. Also note that PWM pins 4 and 5 share a timer, and PWM pins 6 and 7 share a timer. Changing the frequency for one pin will change the frequency for the other pin that is on the timer.

Parameters

pin	the number of the pin to change frequency of. On the SAMD09 breakout, this corresponds to the number on the silkscreen. on the default seesaw firmware on the SAMD09 breakout, pins 5, 6, and 7 are PWM enabled.
freq	the frequency to set.
