LCD5110_Basic Arduino and chipKit library for Nokia 5110 compatible LCDsManualIntroduction:This library has been made to make it easy to use the basic functions of the Nokia 5110 LCD module on an Arduino or a chipKit.Basic functionality of this library are based on the demo-code provided by ITead studio.You can always find the latest version of the library at / For version information, please refer to version.txt.Defined Literals:Alignment For use with print(), printNumI() and printNumF()LEFT: RIGHT: CENTER: 0 9999 9998Included Fonts:SmallFontCharactersize: Number of characters: 6x8 pixels 95MediumNumbersCharactersize: Number of characters: 12x16 pixels 13BigNumbersCharactersize: Number of characters: 14x24 pixels 13Functions:LCD5110(SCK, MOSI, DC, RST, CS);The main class constructor.Parameters: SCK: Pin for Clock signalMOSI: Pin for Data transferDC: Pin for Register Select (Data/Command)RST: Pin for ResetCS: Pin for Chip SelectUsage: LCD5110 myGLCD(8, 9, 10, 11, 12); // Start an instance of the LCD5110 classInitLCD([contrast]);Initialize the LCD.Parameters: contrast: <optional>Specify a value to use for contrast (0-127)Default is 70Usage: myGLCD.initLCD(); // Initialize the displayNotes: This will reset and clear the display.setContrast(contrast);Set the contrast of the LCD.Parameters: contrast: Specify a value to use for contrast (0-127)Usage: myGLCD.setContrast(70); // Sets the contrast to the default value of 70enableSleep();Put the display in Sleep Mode.Parameters: NoneUsage: myGLCD.enableSleep(); // Put the display into Sleep ModeNotes: Entering Sleep Mode will not turn off the backlight as this is a hardware function.disableSleep();Re-enable the display after it has been put in Sleep Mode.Parameters: NoneUsage: myGLCD.disableSleep(); // Wake the display after putting it into Sleep Mode Notes: The display will automatically be cleared when Sleep Mode is disabled.Exiting Sleep Mode will not turn on the backlight as this is a hardware function.clrScr();Clear the screen.Parameters: NoneUsage: myGLCD.clrScr(); // Clear the screenclrRow(row[, start_x[, end_x]]);Clear a part of, or a whole row.Parameters: row: 8 pixel high row to clear (0-5)start_x: <optional>x-coordinate to start the clearing on (default = 0)end_x: <optional>x-coordinate to end the clearing on (default = 83)Usage: myGLCD.clrRow(5, 42); // Clear the right half of the lower rowinvert(mode);Set inversion of the display on or off.Parameters: mode: true - Invert the displayfalse – Normal displayUsage: myGLCD.invert(true); // Set display inversion onprint(st, x, y);Print a string at the specified coordinates.You can use the literals LEFT, CENTER and RIGHT as the x-coordinate to align the string on the screen.Parameters: st: the string to printx: x-coordinate of the upper, left corner of the first charactery: y-coordinate of the upper, left corner of the first characterUsage: myGLCD.print(“Hello World”,CENTER,0); // Print “Hello World” centered at the top of the screen Notes: The y-coordinate will be adjusted to be aligned with an 8 pixel high display row.In effect only 0, 8, 16, 24, 32 and 40 can be used as y-coordinates.The string can be either a char array or a String objectprintNumI(num, x, y[, length[, filler]]);Print an integer number at the specified coordinates.You can use the literals LEFT, CENTER and RIGHT as the x-coordinate to align the string on the screen.Parameters: num: the value to print (-2,147,483,648 to 2,147,483,647) INTEGERS ONLYx: x-coordinate of the upper, left corner of the first digit/signy: y-coordinate of the upper, left corner of the first digit/signlength: <optional>minimum number of digits/characters (including sign) to displayfiller: <optional>filler character to use to get the minimum length. The character will be inserted in frontof the number, but after the sign. Default is ' ' (space).Usage: myGLCD.print(num,CENTER,0); // Print the value of “num” centered at the top of the screenNotes: The y-coordinate will be adjusted to be aligned with an 8 pixel high display row.In effect only 0, 8, 16, 24, 32 and 40 can be used as y-coordinates.printNumF(num, dec, x, y[, divider[, length[, filler]]]);Print a floating-point number at the specified coordinates.You can use the literals LEFT, CENTER and RIGHT as the x-coordinate to align the string on the screen.WARNING: Floating point numbers are not exact, and may yield strange results when compared. Use at your own discretion.Parameters: num: the value to print (See note)dec: digits in the fractional part (1-5) 0 is not supported. Use printNumI() instead.x: x-coordinate of the upper, left corner of the first digit/signy: y-coordinate of the upper, left corner of the first digit/signdivider: <Optional>Single character to use as decimal point. Default is '.'length: <optional>minimum number of digits/characters (including sign) to displayfiller: <optional>filler character to use to get the minimum length. The character will be inserted in frontof the number, but after the sign. Default is ' ' (space).Usage: myGLCD.print(num, 3, CENTER,0); // Print the value of “num” with 3 fractional digits top centered Notes: Supported range depends on the number of fractional digits used.Approx range is +/- 2*(10^(9-dec))The y-coordinate will be adjusted to be aligned with an 8 pixel high display row.In effect only 0, 8, 16, 24, 32 and 40 can be used as y-coordinates.setFont(fontname);Select font to use with print(), printNumI() and printNumF().Parameters: fontname: Name of the array containing the font you wish to useUsage: myGLCD.setFont(SmallFont); // Select the font called SmallFontNotes: You must declare the font-array as an external or include it in your sketch.invertText(mode);Select if text printed with print(), printNumI() and printNumF() should be inverted.Parameters: mode: true - Invert the textfalse – Normal textUsage: myGLCD.invertText(true); // Turn on inverted printingNotes: SetFont() will turn off inverted printingdrawBitmap (x, y, data, sx, sy);Draw a bitmap on the screen.Parameters: x: x-coordinate of the upper, left corner of the bitmapy: y-coordinate of the upper, left corner of the bitmapdata: array containing the bitmap-datasx: width of the bitmap in pixelssy: height of the bitmap in pixelsUsage: myGLCD.drawBitmap(0, 0, bitmap, 32, 32); // Draw a 32x32 pixel bitmap in the upper left corner Notes: You can use the online-tool “ImageConverter Mono” to convert pictures into compatible arrays.The online-tool can be found on my website.Requires that you #include <avr/pgmspace.h> when using an Arduino other than Arduino Due.。
