Member Enumeration Documentation

enum Digi::Drivers::GPIO::DirectionValue

Direction Value enumeration Enumeration of the possible direcition asigned to a gpio.

            // Use of the constants
            DirectionValue.Input
            DirectionValue.Output
            DirectionValue.Undefined

enum Digi::Drivers::GPIO::IoValue

Input/Output Value enumeration Enumeration of the value of a gpio configured as input/output.

            // Use of the constants
            IoValue.Low
            IoValue.High

enum Digi::Drivers::GPIO::IrqValue

Interrupt Value enumeration Enumeration of the possible value of a gpio configured as interrupt.

            // Use of the constants
            IrqValue.LowLevel
            IrqValue.HighLevel
            IrqValue.RisingEdge

Member Function Documentation

public abstract bool Digi::Drivers.GPIO::Poll	(	IoValue	value,
		uint	tries,
		int	sleep
	)			[pure virtual]

Function that makes a polling of the gpio.

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

Implemented in Digi.Drivers.GPIOiMX51, and GPIO_IOEXPANSORiMX51.

public abstract int Digi::Drivers.GPIO::Wait

(

)

[pure virtual]

Function that wait for the configured interrupt in a gpio configured as interrupt.

Returns:

true indicates success, false indicates failure

Implemented in Digi.Drivers.GPIOiMX51, and GPIO_IOEXPANSORiMX51.
