Detailed Description

Class for handling GPIO pins Use it to read from or write to a pin

Constructor & Destructor Documentation

GPin::GPin	(	const char *	strPinName,
		PINTYPE	pinType,
		int	pinNumber,
		int	pinValue
	)

Constructor for the GPin object You will need to porovide name, type, number and a starting value of the pin

Parameters

strPinName	Name of the pin
pinType	Type of the pin

Possible pin types are:

PINTYPE_INPUT_ANALOG : "Read method analogRead shall be used"

PINTYPE_INPUT_DIGITAL : "Read method digitalRead shall be used"

PINTYPE_OUTPUT_ANALOG : "Write method analogWrite shall be used"

PINTYPE_OUTPUT_DIGITAL : "Write method digitalWrite shall be used"

PINTYPE_OUTPUT_VIRTUAL : "A pin not connected to hardware, but can store values"

Parameters

pinNumber	Number of the pin. That is the GPIO number
pinValue	The value to set the pin to

GPin::~GPin

(

)

Deconstructor for the pin

Member Function Documentation

String GPin::getName

(

)

Gets a pin name

Returns

A String containing the pin name

int GPin::getNumber

(

)

Get the number of a pin.

You can then use this number to search for the index of the pin in the GPins object

Returns

The number of the pin. ps. this is not the Index of a pin.

int GPin::getType

(

)

Gets the type of the pin

Possible pin types are:

PINTYPE_INPUT_ANALOG : "Read method analogRead shall be used"

PINTYPE_INPUT_DIGITAL : "Read method digitalRead shall be used"

PINTYPE_OUTPUT_ANALOG : "Write method analogWrite shall be used"

PINTYPE_OUTPUT_DIGITAL : "Write method digitalWrite shall be used"

PINTYPE_OUTPUT_VIRTUAL : "A pin not connected to hardware, but can store values"

Returns

The type of the pin

int GPin::getValue

(

bool

readValueFromHardware = true

)

Read a pin value. If input type is PINTYPE_INPUT_DIGITAL or PINTYPE_INPUT_ANALOG and readValueFromHardware is true then a read will be maid directly to the hardwarepin. otherwise the old member value will be returned.

Parameters

readValueFromHardware

Returns

The value as an int

void GPin::setName

(

const char *

strPinName

)

Assigns a name to a specific pin

Parameters

strPinName

Name of the pin

void GPin::setValue

(

int

value

)

Sets a new value to a pin If the pin is of the type PINTYPE_OUTPUT_ANALOG or PINTYPE_OUTPUT_DIGITAL Then the GPIO pin of the device will be changed to this value.

Parameters

value

The new value to set

String GPin::toJson

(

)

Converts the pin -name, -number, -type and -value to a valid json object string

Returns

A json object string with information about pin members

String GPin::toJsonKeyValue

(

)

Returns pin number and value as a Key value pair with no surrounding curly brackets

Returns

A key value string which can be added to a Json object string
