Detailed Description

Digital I/O functions: pinMode(), digitalWrite(), digitalRead() and digitalToggle().

Function Documentation

digitalRead()

PinStatus digitalRead

(

pin_size_t

pinNumber

)

Read the value of a digital pin.

Parameters

pinNumber

Pin number, Dx or x.

Returns

HIGH or LOW. LOW if the pin is invalid.

digitalToggle()

void digitalToggle

(

pin_size_t

pinNumber

)

Toggle the value from a specified digital pin.

Parameters

pinNumber

The number of the digital pin you want to toggle.

digitalWrite()

void digitalWrite	(	pin_size_t	pinNumber,
		PinStatus	status
	)

Write a HIGH or LOW value to a digital pin.

Parameters

pinNumber	Pin number, Dx or x.
status	HIGH or LOW.

pinMode()

void pinMode	(	pin_size_t	pinNumber,
		PinMode	pinMode
	)

Set the mode of a pin.

If the pin was used for PWM or DAC output (analogWrite()), the output is stopped first. Any unsupported mode calls Error_Handler().

Parameters

pinNumber	Pin number, Dx or x.
pinMode	INPUT, INPUT_PULLUP, INPUT_PULLDOWN, INPUT_ANALOG, OUTPUT or OUTPUT_OPEN_DRAIN.
