Remarks
This is a generic GPIO driver for Allwinner SoCs. It can even drive the internal pins that are not drawn out. Before you operate, you must be clear about what you are doing.
Constructors
SunxiDriver() |
Initializes a new instance of the SunxiDriver class. |
SunxiDriver(Int32, Int32) |
Initializes a new instance of the SunxiDriver. |
Properties
CpusPortBaseAddress |
CPUS-PORT base address. |
CpuxPortBaseAddress |
CPUX-PORT base address. |
PinCount |
The number of pins provided by the driver. |
Methods
AddCallbackForPinValueChangedEvent(Int32, PinEventTypes, PinChangeEventHandler) |
Adds a handler for a pin value changed event. |
ClosePin(Int32) |
Closes an open pin. |
ConvertPinNumberToLogicalNumberingScheme(Int32) |
Converts a board pin number to the driver's logical numbering scheme. |
Dispose() |
Disposes this instance, closing all open pins (Inherited from GpioDriver) |
Dispose(Boolean) |
Disposes this instance |
GetPinMode(Int32) |
Gets the mode of a pin. |
IsPinModeSupported(Int32, PinMode) |
Checks if a pin supports a specific mode. |
MapPinNumber(Char, Int32) |
Map pin number with port controller name to pin number in the driver's logical numbering scheme. |
OpenPin(Int32) |
Opens a pin in order for it to be ready to use. This retains the pin direction, but if it is output, the value will always be low after open. |
QueryComponentInformation() |
Query information about a component and its children. (Inherited from GpioDriver) |
Read(Int32) |
Reads the current value of a pin. |
RemoveCallbackForPinValueChangedEvent(Int32, PinChangeEventHandler) |
Removes a handler for a pin value changed event. |
SetPinMode(Int32, PinMode) |
Sets the mode to a pin. |
SetPinMode(Int32, PinMode, PinValue) |
Sets the mode to a pin and sets an initial value for an output pin. (Inherited from GpioDriver) |
Toggle(Int32) |
Toggle the current value of a pin. (Inherited from SysFsDriver) |
UnmapPinNumber(Int32) |
Unmap pin number in the driver's logical numbering scheme to pin number with port name. |
WaitForEvent(Int32, PinEventTypes, CancellationToken) |
Blocks execution until an event of type eventType is received or a cancellation is requested. |
WaitForEventAsync(Int32, PinEventTypes, CancellationToken) |
Async call until an event of type eventType is received or a cancellation is requested. |
Write(Int32, PinValue) |
Writes a value to a pin. |
