C# Класс CyrusBuilt.MonoPi.Components.Potentiometers.Microchip.MicrochipPotDeviceController

An MCP45XX and MCP46XX device controller component. This mostly a port of the device controller in the Pi4J project (Java port author Raspelikan) which is a port of similar C++ code from Stibro's code blog.

Открытые методы

Метод Описание
Decrease ( DeviceControlChannel channel, Int32 steps ) : void

Decriments the volatile wiper for the given number of steps.
Dispose ( ) : void

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

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

GetTerminalConfiguration ( DeviceControlChannel channel ) : DeviceControllerTerminalConfiguration

Gets the terminal configuration for the specified channel.
GetValue ( DeviceControlChannel channel, System.Boolean nonVolatile ) : Int32

Receives the current wiper's value from the device.
Increase ( DeviceControlChannel channel, Int32 steps ) : void

Increments the volatile wiper for the given number of steps.
MicrochipPotDeviceController ( II2CBus device, Int32 busAddress ) : System

Initializes a new instance of the CyrusBuilt.MonoPi.Components.Potentiometers.Microchip.MicrochipPotDeviceController class with the I2C bus device this instance is connected to and the bus address of that device.
SetTerminalConfiguration ( DeviceControllerTerminalConfiguration config ) : void

Sets the device's terminal configuration.
SetValue ( DeviceControlChannel channel, Int32 value, System.Boolean nonVolatile ) : void

Sets the wiper's value in the device.
SetWiperLock ( DeviceControlChannel channel, System.Boolean locked ) : void

Enables or disables the wiper's lock.
SetWriteProtection ( System.Boolean enabled ) : void

Enables or disables the device's write-protection.

Приватные методы

Метод Описание
IncreaseOrDecrease ( Byte memAddr, System.Boolean increase, Int32 steps ) : void

Writes n (steps) bytes to the device holding the wiper's address and the increment or decrement command and value.
Read ( Byte memAddr ) : Int32

Reads two bytes from the device at the given memory address.
SetBit ( Int32 mem, Int32 mask, System.Boolean val ) : Int32

Sets or clears a bit in the specified memory (integer).
Write ( Byte memAddr, Int32 val ) : void

Writes 9 bits of the give value to the device.
