Constructor & Destructor Documentation

public GPIO_IOEXPANSORiMX51::GPIO_IOEXPANSORiMX51

(

uint

PinNumber

)

Constructor, need pin number.

Parameters:

PinNumber

Pin number to be open

public GPIO_IOEXPANSORiMX51::GPIO_IOEXPANSORiMX51	(	uint	PinNumber,
		DirectionValue	PinDirection
	)

Constructor, need pin number and direction.

Parameters:

	PinNumber	Pin number to be open
	PinDirection	Direction of the pin (use DirectionValue constants)

public GPIO_IOEXPANSORiMX51::GPIO_IOEXPANSORiMX51	(	uint	PinNumber,
		DirectionValue	PinDirection,
		IoValue	PinValue
	)

Member Function Documentation

public override bool GPIO_IOEXPANSORiMX51::Poll	(	IoValue	value,
		uint	tries,
		int	sleep
	)			[virtual]

Function that makes a polling of the pin.

Parameters:

	value	Input value to be pooled (use IoValue constants)
	tries	Number of tries to achieve the value
	sleep	Time to wait between tries

Returns:

true indicates success, false indicates failure

        // Wait for a specific value in the gpio configured as input
        if(mygpio.Poll(IoValue.Low,100,1))
            MessageBox.Show("poll achieved"); 
        else
            MessageBox.Show("poll not achieved");

public bool GPIO_IOEXPANSORiMX51::Invert [get, set]

Get/Set Invert property of the gpio (use true/false values).

        //use boolean values (true/false)
        mygpio.Invert = true;
        bool Value = Invert.Value;

public override IrqValue GPIO_IOEXPANSORiMX51::IrqMode [get, set]

Not supported.

Reimplemented from Digi.Drivers.GPIO.

public override IoValue GPIO_IOEXPANSORiMX51::Value [get, set]

Get/Set the value of the gpio (use IoValue constants).

        //use IoValue constants (IoValue.High / IoValue.Low)
        mygpio.Value = IoValue.High;
        IoValue Value = mygpio.Value;

Reimplemented from Digi.Drivers.GPIO.
