C# Class CyrusBuilt.MonoPi.IO.GpioMem

Raspberry Pi GPIO using the direct memory access method. This requires the bcm2835 GPIO library provided by Mike McCauley ([email protected]) at http://www.open.com.au/mikem/bcm2835/index.html. To create the shared object, download the source code from the link above. The standard Makefile compiles a statically linked library. To build a shared object, do: tar -zxf bcm2835-1.3.tar.gz cd bcm2835-1.3/src make libbcm2835.a cc -shared bcm2835.o -o libbcm2835.so Place the shared object in the same directory as the executable and other assemblies.

Méthodes publiques

Méthode	Description
Destroy ( ) : void	Destroy this GPIO factory.
Dispose ( ) : void	Releases all resource used by the CyrusBuilt.MonoPi.IO.GpioMem object. Call Dispose when you are finished using the CyrusBuilt.MonoPi.IO.GpioMem. The Dispose method leaves the CyrusBuilt.MonoPi.IO.GpioMem in an unusable state. After calling Dispose, you must release all references to the CyrusBuilt.MonoPi.IO.GpioMem so the garbage collector can reclaim the memory that the CyrusBuilt.MonoPi.IO.GpioMem was occupying.
GpioMem ( GpioPins pin ) : System	Initializes a new instance of the CyrusBuilt.MonoPi.IO.GpioMem class with the pin to initialize. Access to the specified GPIO setup as an output port with an initial value of false (0).
GpioMem ( GpioPins pin, PinMode mode ) : System	Initializes a new instance of the CyrusBuilt.MonoPi.IO.GpioMem class with the pin to initialize and the I/O direction. Access to the specified GPIO setup with the specified direction with an initial value of LOW (0).
GpioMem ( GpioPins pin, PinMode mode, PinState initialValue ) : System	Initializes a new instance of the CyrusBuilt.MonoPi.IO.GpioMem class with the pin to initialize, the I/O direction, and the initial value to write to the pin. Access to the specified GPIO setup with the specified direction with the specified initial value.
Initialize ( ) : System.Boolean	Initialize the memory access to the GPIO.
Provision ( ) : void	Provisions the pin (initialize to specified mode and make active).
Pulse ( ) : void	Pulses the pin for 500ms.
Pulse ( Int32 millis ) : void	Pulse the pin output for the specified number of milliseconds.
Read ( ) : PinState	Read a value from the pin.
Read ( GpioPins pin ) : PinState	Read the specified Revision 1.0 pin.
Write ( GpioPins pin, PinState value ) : void	Write the specified pin and value.
Write ( PinState value ) : void	Write the specified value to the pin.

Private Methods

Méthode	Description
ExportPin ( GpioPins pin, PinMode mode ) : void	Exports the pin setting the direction.
UnexportPin ( GpioPins pin ) : void	Unexport the GPIO.
internal_ExportPin ( Int32 pin, PinMode mode ) : void	Export the GPIO setting the direction.
internal_Read ( Int32 pin, String pinname ) : PinState	Read the value of the specified pin.
internal_UnexportPin ( Int32 pin, String gpionum ) : void	Unexports an exported pin.
internal_Write ( Int32 pin, PinState value, String pinname ) : void	Write the value to the specified pin.

Method Details

Destroy() public static méthode

Destroy this GPIO factory.

public static Destroy ( ) : void
Résultat	void

Dispose() public méthode

Releases all resource used by the CyrusBuilt.MonoPi.IO.GpioMem object.

Call Dispose when you are finished using the CyrusBuilt.MonoPi.IO.GpioMem. The Dispose method leaves the CyrusBuilt.MonoPi.IO.GpioMem in an unusable state. After calling Dispose, you must release all references to the CyrusBuilt.MonoPi.IO.GpioMem so the garbage collector can reclaim the memory that the CyrusBuilt.MonoPi.IO.GpioMem was occupying.
