Detailed Description

template<uint16_t N>
class AH::StaticSizeExtendedIOElement< N >

A class for ExtendedIOElements with a fixed size.

This class is to make it easier to get an array of all pins of the element.

Definition at line 19 of file StaticSizeExtendedIOElement.hpp.

Member Function Documentation

◆ pins()

template<uint16_t N>

Array<pin_t, N> AH::StaticSizeExtendedIOElement< N >::pins ( ) const

inline

Get an array containing all pins of the element.

Definition at line 27 of file StaticSizeExtendedIOElement.hpp.

◆ length()

template<uint16_t N>

static constexpr uint16_t AH::StaticSizeExtendedIOElement< N >::length ( )

inlinestaticconstexpr

Definition at line 31 of file StaticSizeExtendedIOElement.hpp.

◆ pinMode()

virtual void AH::ExtendedIOElement::pinMode	(	pin_t	pin,
		uint8_t	mode
	)

pure virtualinherited

Set the mode of a given pin.

Note: This function might not be implemented by all subclasses.
Some extended IO types, such as shift registers, can only be used as outputs.
On others, it might be implemented, but it could impact all pins of the IO element. For example, enabling the internal pull-up resistor on an analog multiplexer affects all pins of the mux.

Parameters

pin	The (zero-based) pin of this IO element.
mode	The mode to set the pin to (e.g. `INPUT`, `OUTPUT` or `INPUT_PULLUP`).

Implemented in AH::ShiftRegisterOutBase< N >, AH::MAX7219, and AH::AnalogMultiplex< N >.

◆ digitalWrite()

virtual void AH::ExtendedIOElement::digitalWrite	(	pin_t	pin,
		uint8_t	state
	)

pure virtualinherited

Set the output of the given pin to the given state.

Parameters

pin	The (zero-based) pin of this IO element.
state	The new state to set the pin to.

Implemented in AH::AnalogMultiplex< N >, AH::ShiftRegisterOutBase< N >, and AH::MAX7219.

◆ digitalRead()

virtual int AH::ExtendedIOElement::digitalRead ( pin_t pin )

pure virtualinherited

Parameters

pin	The (zero-based) pin of this IO element.

Returns: The state of the given pin.

Implemented in AH::AnalogMultiplex< N >, AH::ShiftRegisterOutBase< N >, and AH::MAX7219.

◆ analogWrite()

virtual void AH::ExtendedIOElement::analogWrite	(	pin_t	pin,
		analog_t	val
	)

pure virtualinherited

Write an analog (or PWM) value to the given pin.

Parameters

pin	The (zero-based) pin of this IO element.
val	The new analog value to set the pin to.

Implemented in AH::AnalogMultiplex< N >, AH::ShiftRegisterOutBase< N >, and AH::MAX7219.

◆ analogRead()

virtual analog_t AH::ExtendedIOElement::analogRead ( pin_t pin )

pure virtualinherited

Read the analog value of the given pin.

Parameters

staticinherited

Initialize all extended IO elements.

Definition at line 23 of file ExtendedIOElement.cpp.

◆ update()

virtual void AH::ExtendedIOElement::update ( )

pure virtualinherited

Update the extended IO element: write the internal state to the physical outputs, or read the physical state into the input buffers.

Implemented in AH::MAX7219, AH::AnalogMultiplex< N >, AH::ShiftRegisterOut< N >, and AH::SPIShiftRegisterOut< N >.
