Lcd2004(LcdInterface)

Constructs a new LCD 20x4 controller with the given interface

public Lcd2004 (Iot.Device.CharacterLcd.LcdInterface lcdInterface);

new Iot.Device.CharacterLcd.Lcd2004 : Iot.Device.CharacterLcd.LcdInterface -> Iot.Device.CharacterLcd.Lcd2004

Public Sub New (lcdInterface As LcdInterface)

Parameters

lcdInterface

LcdInterface

The LCD Interface

Lcd2004(I2cDevice, Boolean)

Constructs a new HD44780 based 16x2 LCD controller with integrated I2c support.

public Lcd2004 (System.Device.I2c.I2cDevice device, bool uses8Bit = true);

new Iot.Device.CharacterLcd.Lcd2004 : System.Device.I2c.I2cDevice * bool -> Iot.Device.CharacterLcd.Lcd2004

Public Sub New (device As I2cDevice, Optional uses8Bit As Boolean = true)

Parameters

device

I2cDevice

The I2c device for the LCD.

uses8Bit

Boolean

True if the device uses 8 Bit commands, false if it handles only 4 bit commands.

Remarks

This is for on-chip I2c support. For connecting via I2c GPIO expanders, use the GPIO constructor Lcd1602(Int32, Int32, Int32[], Int32, Single, Int32, GpioController, Boolean).

Lcd2004(Int32, Int32, Int32[], Int32, Single, Int32, GpioController, Boolean)

Constructs a new HD44780 based 20x4 LCD controller.

public Lcd2004 (int registerSelectPin, int enablePin, int[] dataPins, int backlightPin = -1, float backlightBrightness = 1, int readWritePin = -1, System.Device.Gpio.GpioController? controller = default, bool shouldDispose = true);

new Iot.Device.CharacterLcd.Lcd2004 : int * int * int[] * int * single * int * System.Device.Gpio.GpioController * bool -> Iot.Device.CharacterLcd.Lcd2004

Public Sub New (registerSelectPin As Integer, enablePin As Integer, dataPins As Integer(), Optional backlightPin As Integer = -1, Optional backlightBrightness As Single = 1, Optional readWritePin As Integer = -1, Optional controller As GpioController = Nothing, Optional shouldDispose As Boolean = true)

Parameters

registerSelectPin

Int32

The pin that controls the regsiter select.

enablePin

Int32

The pin that controls the enable switch.

dataPins

Int32[]

Collection of pins holding the data that will be printed on the screen.

backlightPin

Int32

The optional pin that controls the backlight of the display.

backlightBrightness

Single

The brightness of the backlight. 0.0 for off, 1.0 for on.

readWritePin

Int32

The optional pin that controls the read and write switch.

controller

GpioController

The controller to use with the LCD. If not specified, uses the platform default.

shouldDispose

Boolean

True to dispose the Gpio Controller
