Constructor & Destructor Documentation

GPins::GPins

(

)

Constructor for the GPins Object

Member Function Documentation

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

Adds a pin

Parameters

strPinName	The name of the pin
pinType	Type of the pin

Possible types of a pin 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 (GPIO number)
pinValue	Starting value of the pin. If the pin type is an input pin then the value will be read from the hardware and this value ignored.

Returns

The number of pins after the pin was added.

int GPins::count

(

)

Gets the number of pins.

Returns

Number of GPin objects in the GPins object

boolean GPins::exists

(

int

pinNumber

)

Checks if a pin with a given number exits.

Parameters

pinNumber

Returns

true if a pin was found otherwise false

GPin * GPins::get

(

int

pinNumber

)

Gets a pointer to a GPin

Parameters

pinNumber

The pin number to search for

Returns

A pointer to the GPin ojbect. Returns NULL if pin is not found

int GPins::getValue

(

int

pinNumber

)

Gets a value of a pin

Parameters

pinNumber

The pin to get the value from

Returns

The value of the given pin.

Returns -1 if pinNumber was not found

String GPins::JsonPinout

(

)

Creates a JSON object containg all pins name and their number.

Returns

A string formatted as a JSON object which contains all pin names and number.

boolean GPins::setValue	(	int	pinNumber,
		int	newValue
	)

Sets the value of a pin with the given number.

Parameters

pinNumber	The number of the pin to search for
newValue	The new value to be set

Returns

True if value was set. False if value was not set because no pin with given pin number was not found.

String GPins::toJson

(

)

Returns all pin values in a json array a key-value Json object with the '{' and '}' around it. where first key is the first in the index with the key as the GPO key and the value is the last value set to that key.

Returns

A Json object string containing status of all pins in the GPins object
