A fork of Chris Yan's Nokia 5110 LCD library, adapted to LPC1347. Should work on a DipCortex M3 and an EzSBC2 dev board.

00001 // Project: Nokia5110 - Controlling a NK5110 display from an NXP LPC1768 00002 // File: NOKIA_5110.h 00003 // Author: Chris Yan 00004 // Created: January, 2012 00005 // Revised: January, 2014 00006 // Desc: Commands, fonts, and class for using a 00007 // Nokia 5110 LCD via the Phillips 8554 LCD driver. 00008 // 00009 // Typical Usage: User must fill the LcdPins struct with the pinout used to control the LCD and 00010 // instantiate the NokiaLcd class - passing the created LcdPins struct to the constructor. 00011 // The class function NokiaLcd::InitLcd may then be called to reset and start the LCD driver. 00012 // A simple 6x6 font (6x8 in LCD space and ~5x5 character space) is included to facilitate 00013 // the NokiaLcd::DrawChar( char character ) function, which will copy the character 8 bits 00014 // at a time for 6 clock cycles. 00015 // Commands may be sent to the LCD via the NokiaLcd::SendFunction(char cmd) 00016 // function, but be aware that certain commands require the Function Set register's H-value 00017 // to be either 1 or 0, depending on the command. This class does not check to see whether 00018 // the H-value is of proper status. The Function Set register /may/ be changed via the 00019 // NokiaLcd::SendFunction(char cmd), but the code uses this internally and expects that 00020 // most function registers have not been changed by the user. 00021 // 00022 // Example: 00023 // #include "mbed.h" 00024 // #include "NOKIA_5110.h" 00025 // 00026 // int main() { 00027 // LcdPins myLcdPins = { p11, NC, p13, p10, p8, p9 }; 00028 // NokiaLcd myLcd( myLcdPins ); // SPI is started here (8-bits, mode 1) 00029 // myLcd.InitLcd(); // LCD is reset and DDRAM is cleared 00030 // myLcd.TestLcd( 0xAA ); // Draws a vertical pattern where every other pixel is on 00031 // wait(10); 00032 // myLcd.ShutdownLcd(); // Clears the LCD's DDRAM and powers it down via CMD_FS_POWER_DOWN_MODE, H=0 00033 // while(1) 00034 // { }; 00035 // } 00036 00037 // Command Instructions 00038 // H = 0 00039 #ifndef __NOKIA_5110_H__ 00040 #define __NOKIA_5110_H__ 00041 00042 // Command Instructions 00043 // H = 0 00044 #define CMD_DC_CLEAR_DISPLAY 0x08 00045 #define CMD_DC_NORMAL_MODE 0x0C 00046 #define CMD_DC_FILL_DISPLAY 0x09 00047 #define CMD_DC_INVERT_VIDEO 0x0D 00048 #define CMD_FS_HORIZONTAL_MODE 0x00 00049 #define CMD_FS_VERTICAL_MODE 0x02 00050 #define CMD_FS_BASIC_MODE 0x00 00051 #define CMD_FS_EXTENDED_MODE 0x01 00052 #define CMD_FS_ACTIVE_MODE 0x00 00053 #define CMD_FS_POWER_DOWN_MODE 0x04 00054 // H = 1 00055 #define CMD_TC_TEMP_0 0x04 00056 #define CMD_TC_TEMP_1 0x05 00057 #define CMD_TC_TEMP_2 0x06 00058 #define CMD_TC_TEMP_3 0x07 00059 #define CMD_BI_MUX_24 0x15 00060 #define CMD_BI_MUX_48 0x13 00061 #define CMD_BI_MUX_100 0x10 00062 #define CMD_VOP_6V06 0xB2 00063 #define CMD_VOP_7V38 0xC8 00064 00065 // LCD Characteristics 00066 #define LCD_FREQ 2000000 00067 #define LCD_SPI_MODE 0x01 00068 #define LCD_SPI_BITS 0x08 00069 #define LCD_X_MAX 84 00070 #define LCD_Y_MAX 48 00071 00072 #define PIN_RST 0x00 00073 #define PIN_SCE 0x01 00074 #define PIN_DC 0x02 00075 00076 #include "mbed.h" 00077 00078 struct LcdPins 00079 { 00080 PinName mosi; 00081 PinName miso; 00082 PinName sclk; 00083 PinName dc; 00084 PinName sce; 00085 PinName rst; 00086 }; 00087 00088 struct LcdFunctionSet 00089 { 00090 char PD; 00091 char V; 00092 char H; 00093 }; 00094 00095 typedef char LcdFunctionChar; 00096 typedef char LcdTempControl; 00097 typedef char LcdDispControl; 00098 typedef char LcdBiasChar; 00099 typedef char LcdVopChar; 00100 00101 class NokiaLcd 00102 { 00103 public: 00104 NokiaLcd(LcdPins lcd_pinout); 00105 ~NokiaLcd(); 00106 00107 public: 00108 void InitLcd(); 00109 void ClearLcdMem(); 00110 void ShutdownLcd(); 00111 void SendFunction(char cmd); 00112 void TestLcd(char test_pattern); 00113 void SendDrawData(char data); 00114 00115 public: 00116 void DrawString(char* str); 00117 void DrawChar(char character); 00118 void SetXY(char x, char y); 00119 void DrawFrameChar(char character); 00120 void DrawNegFrameChar(char character); 00121 char* NumToStr(int num); 00122 00123 private: 00124 char CreateFunctionChar(); 00125 void ResetLcd(); 00126 00127 private: 00128 LcdFunctionChar FunctionChar; 00129 LcdTempControl TempControlChar; 00130 LcdDispControl DispControlChar; 00131 LcdFunctionSet FunctionSet; 00132 LcdBiasChar BiasChar; 00133 LcdVopChar VopChar; 00134 DigitalOut** Pins; 00135 SPI* LcdSpi; 00136 00137 }; 00138 00139 const char FONT_6x6[570] = //should be 564 total char 00140 { 00141 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, // SPACE 1 00142 0x00, 0x06, 0x2F, 0x06, 0x00, 0x00, // ! 2 00143 0x00, 0x06, 0x00, 0x06, 0x00, 0x00, // " 3 00144 0x14, 0x3E, 0x14, 0x3E, 0x14, 0x00, // # 4 00145 0x2E, 0x2A, 0x3F, 0x2A, 0x3A, 0x00, // $ 5 00146 0x26, 0x16, 0x08, 0x34, 0x32, 0x00, // % 6 00147 0x34, 0x2A, 0x3C, 0x18, 0x28, 0x00, // & 7 00148 0x00, 0x06, 0x00, 0x00, 0x00, 0x00, // ' 8 00149 0x00, 0x00, 0x1C, 0x36, 0x22, 0x00, // ( 9 00150 0x22, 0x36, 0x1C, 0x00, 0x00, 0x00, // ) 10 00151 0x24, 0x18, 0x0E, 0x18, 0x24, 0x00, // * 11 00152 0x08, 0x08, 0x3E, 0x08, 0x08, 0x00, // + 12 00153 0x20, 0x30, 0x00, 0x00, 0x00, 0x00, // , 13 00154 0x08, 0x08, 0x08, 0x08, 0x08, 0x00, // - 14 00155 0x20, 0x00, 0x00, 0x00, 0x00, 0x00, // . 15 00156 0x30, 0x18, 0x0C, 0x06, 0x00, 0x00, // / 16 00157 0x00, 0x1C, 0x22, 0x22, 0x1C, 0x00, // 0 17 00158 0x00, 0x24, 0x3E, 0x20, 0x00, 0x00, // 1 18 00159 0x3A, 0x2A, 0x2A, 0x2A, 0x2E, 0x00, // 2 19 00160 0x22, 0x2A, 0x2A, 0x2A, 0x3E, 0x00, // 3 20 00161 0x0E, 0x08, 0x08, 0x3E, 0x08, 0x00, // 4 21 00162 0x2E, 0x2A, 0x2A, 0x2A, 0x3A, 0x00, // 5 22 00163 0x3E, 0x2A, 0x2A, 0x2A, 0x3A, 0x00, // 6 23 00164 0x22, 0x12, 0x0A, 0x06, 0x02, 0x00, // 7 24 00165 0x3E, 0x2A, 0x2A, 0x2A, 0x3E, 0x00, // 8 25 00166 0x00, 0x2E, 0x2A, 0x2A, 0x3E, 0x00, // 9 26 00167 0x00, 0x00, 0x14, 0x00, 0x00, 0x00, // : 27 00168 0x00, 0x20, 0x14, 0x00, 0x00, 0x00, // ; 28 00169 0x00, 0x00, 0x08, 0x14, 0x22, 0x00, // < 29 00170 0x14, 0x14, 0x14, 0x14, 0x14, 0x00, // = 30 00171 0x22, 0x14, 0x08, 0x00, 0x00, 0x00, // > 31 00172 0x06, 0x01, 0x2D, 0x06, 0x00, 0x00, // ?
