Detailed Description

GPIO Pin Vector Base Class.

This class is for building semi-parallel buses using GPIO pins. It facilitates driving a numeric value across a parallel bus of GPIO pins. It should not be confused with a true parallel bus, as each individual pin in the bus is modified sequentially/independently during a bus assignment.

Parameters

_Pin::len

Number of pins managed by the _PinVector.

Member Function Documentation

config() [1/2]

void _PinVector::config	(	PinIO *	pinCfgs,
		uint32_t	count )

Configure the _PinVector based on an array of PinIOs. The index of the PinIO in the configuration array will determine the bit position within the _PinVector that that PinIO represents.

Parameters

pinCfgs	The configuration to be used.
count	The number of PinIOs in the configuration array to be used.

config() [2/2]

void _PinVector::config	(	uint32_t	idx,
		PinIO	cfg )

Set the PinIO that will be used for a given bit position in the _PinVector.

Parameters

idx	The bit position to be configured.
cfg	The PinIO that bit position will represent.

operator uint32_t()

_PinVector::operator uint32_t

(

)

const

Read the line state of the _PinVector bus.

Returns

The current bus value as read from the line state.

operator=()

uint32_t _PinVector::operator=

(

uint32_t

val

)

Assign a value to the _PinVector Bus.

Parameters

val	The value to assign to the bus.

Returns

The value driven on the bus.

operator[]()

PinIO _PinVector::operator[]

(

int

idx

)

Access the PinIO for a specific bit position in the _PinVector.

Parameters

idx	The bit index to access in the _PinVector.

Returns

The PinIO for the given bit position.
