This code writes a series of images and text to the Nokia 5110 84x48 graphic LCD: http://www.sparkfun.com/products/10168 Do not drive the backlight with 5V. It will smoke. However, the backlight on the LCD seems to be happy with direct drive from the 3.3V regulator. Although the PCD8544 controller datasheet recommends 3.3V, the graphic Nokia 5110 LCD can run at 3.3V or 5V. No resistors needed on the signal lines. You will need 5 signal lines to connect to the LCD, 3.3 or 5V for power, 3.3V for LED backlight, and 1 for ground. */ #define PIN_SCE 7 //Pin 3 on LCD #define PIN_RESET 6 //Pin 4 on LCD #define PIN_DC 5 //Pin 5 on LCD #define PIN_SDIN 4 //Pin 6 on LCD #define PIN_SCLK 3 //Pin 7 on LCD //The DC pin tells the LCD if we are sending a command or data #define LCD_COMMAND 0 #define LCD_DATA 1 //You may find a different size screen, but this one is 84 by 48 pixels #define LCD_X 84 #define LCD_Y 48 //This table contains the hex values that represent pixels //for a font that is 5 pixels wide and 8 pixels high static const byte ASCII[][5] = { {0x00, 0x00, 0x00, 0x00, 0x00} // 20 ,{0x00, 0x00, 0x5f, 0x00, 0x00} // 21 ! ,{0x00, 0x07, 0x00, 0x07, 0x00} // 22 " ,{0x14, 0x7f, 0x14, 0x7f, 0x14} // 23 # ,{0x24, 0x2a, 0x7f, 0x2a, 0x12} // 24 $ ,{0x23, 0x13, 0x08, 0x64, 0x62} // 25 % ,{0x36, 0x49, 0x55, 0x22, 0x50} // 26 & ,{0x00, 0x05, 0x03, 0x00, 0x00} // 27 ' ,{0x00, 0x1c, 0x22, 0x41, 0x00} // 28 ( ,{0x00, 0x41, 0x22, 0x1c, 0x00} // 29 ) ,{0x14, 0x08, 0x3e, 0x08, 0x14} // 2a * ,{0x08, 0x08, 0x3e, 0x08, 0x08} // 2b + ,{0x00, 0x50, 0x30, 0x00, 0x00} // 2c , ,{0x08, 0x08, 0x08, 0x08, 0x08} // 2d - ,{0x00, 0x60, 0x60, 0x00, 0x00} // 2e . ,{0x20, 0x10, 0x08, 0x04, 0x02} // 2f / ,{0x3e, 0x51, 0x49, 0x45, 0x3e} // 30 0 ,{0x00, 0x42, 0x7f, 0x40, 0x00} // 31 1 ,{0x42, 0x61, 0x51, 0x49, 0x46} // 32 2 ,{0x21, 0x41, 0x45, 0x4b, 0x31} // 33 3 ,{0x18, 0x14, 0x12, 0x7f, 0x10} // 34 4 ,{0x27, 0x45, 0x45, 0x45, 0x39} // 35 5 ,{0x3c, 0x4a, 0x49, 0x49, 0x30} // 36 6 ,{0x01, 0x71, 0x09, 0x05, 0x03} // 37 7 ,{0x36, 0x49, 0x49, 0x49, 0x36} // 38 8 ,{0x06, 0x49, 0x49, 0x29, 0x1e} // 39 9 ,{0x00, 0x36, 0x36, 0x00, 0x00} // 3a : ,{0x00, 0x56, 0x36, 0x00, 0x00} // 3b ;
