Public Member Functions
virtual void	setDirection (Direction dir, uint8_t mask=0xff)=0

virtual void	setPullup (uint8_t state, uint8_t mask=0xff)=0

Public Member Functions inherited from InputPort
virtual uint8_t	getValue (void) const =0

Public Member Functions inherited from OutputPort
virtual void	setValue (uint8_t value, uint8_t mask=0xff)=0

Detailed Description

Interface for 8 bit GPIO ports. GPIO ports are expected to support the directions input and output. The interface also supports control of internal pullup resistors as they are featured by AVR microcontrollers.

Member Function Documentation

◆ setDirection()

virtual void GpioPort::setDirection	(	Direction	dir,
		uint8_t	mask = `0xff`
	)

pure virtual

Configure direction (input/output) for a set of individual pins.

Parameters

dir	Direction to set.
mask	Mask with pins to apply setting to.

Implemented in PortA, PortB, PortC, and PortD.

◆ setPullup()

virtual void GpioPort::setPullup	(	uint8_t	state,
		uint8_t	mask = `0xff`
	)
