C# 클래스 CyrusBuilt.MonoPi.Devices.CrystalFontzSerialLCD.CrystalFontz63xSerial

Provides an API for manipulating a CrystalFontz 632/634 serial LCD display. This API currently *only* works with serial (SPI not yet supported) displays that are 16x2 (16 column, 2 row).

공개 메소드들

메소드 설명
Backspace ( ) : void

Moves the cursor back one space and erases the character in that space.
Begin ( ) : void

Begins communication with the display.
Begin ( DisplayType type ) : void

Begins communication with the display.
CarriageReturn ( ) : void

Moves the cursor to the left-most column of the current row.
ClearDisplay ( ) : void

Clear the contents of the display and return the cursor to its home position (upper left corner, or position 0, 0).
CrLf ( ) : void

Carriage return, line feed. This will move the cursor to the left-most column of the next row (same as calling CarriageReturn followed by LineFeed).
CrystalFontz63xSerial ( ) : System

Initializes a new instance of the CyrusBuilt.MonoPi.Devices.CrystalFontzSerialLCD.CrystalFontz63xSerial class. This is the default constructor.
CrystalFontz63xSerial ( BaudRates baud ) : System

Initializes a new instance of the CyrusBuilt.MonoPi.Devices.CrystalFontzSerialLCD.CrystalFontz63xSerial class with the BAUD rate to negotiate with display.
CrystalFontz63xSerial ( IRaspiGpio backlightPin ) : System

Initializes a new instance of the CyrusBuilt.MonoPi.Devices.CrystalFontzSerialLCD.CrystalFontz63xSerial class with a GPIO pin to use to control the backlight.
CrystalFontz63xSerial ( IRaspiGpio backlightPin, BaudRates baud ) : System

Initializes a new instance of the CyrusBuilt.MonoPi.Devices.CrystalFontzSerialLCD.CrystalFontz63xSerial class with the GPIO pin to control the backlight with and the BAUD rate to negotiate with the display.
CursorHome ( ) : void

Returns the cursor to its home position (upper left corner).
DeleteInPlace ( ) : void

Deletes the character at the current cursor position but does not move the cursor.
Dispose ( ) : void

Releases all resource used by the CyrusBuilt.MonoPi.Devices.CrystalFontzSerialLCD.CrystalFontz63xSerial object.

Call Dispose when you are finished using the CyrusBuilt.MonoPi.Devices.CrystalFontzSerialLCD.CrystalFontz63xSerial. The Dispose method leaves the CyrusBuilt.MonoPi.Devices.CrystalFontzSerialLCD.CrystalFontz63xSerial in an unusable state. After calling Dispose, you must release all references to the CyrusBuilt.MonoPi.Devices.CrystalFontzSerialLCD.CrystalFontz63xSerial so the garbage collector can reclaim the memory that the CyrusBuilt.MonoPi.Devices.CrystalFontzSerialLCD.CrystalFontz63xSerial was occupying.

End ( ) : void

Ends communication with the display.
FormFeed ( ) : void

Clears the display. All data is erased.
LineFeed ( ) : void

Moves the cursor down one row. If scrolling is enabled and the cursor is in the bottom row, the display will scroll up one row and the bottom row will be cleared. If scrolling is NOT enabled, and the cursor is in the bottom row, then it will wrap up to the same character position on the top row.
Print ( String text ) : void

Prints text to the display.
RebootDisplay ( ) : void

Reboot the LCD display. This should only be used to return the display to a usable state, perhaps due to invalid contrast or brightness values or if the display is printing garbage. However, this method is not likely to succeed if the display's controller is in an inoperable or indeterminate state. In such cases, it is best to power-cycle the controller instead.
SetBarGraph ( GraphIndices index, GraphStyle style, UInt16 startCol, UInt16 endCol, UInt16 len, UInt16 row ) : void

Displays/updates a horizontal bar graph.
SetCursorPosition ( UInt16 column, UInt16 row ) : void

Sets the cursor position.
ShowInfoScreen ( ) : void

Displays the LCD controller info screen.
