Fuzball 0:9cfce382e741 1 // Project: Nokia5110 - Controlling a NK5110 display from an NXP LPC1768
Fuzball 0:9cfce382e741 2 // File: NOKIA_5110.h
Fuzball 0:9cfce382e741 3 // Author: Chris Yan
Fuzball 0:9cfce382e741 4 // Created: January, 2012
Fuzball 0:9cfce382e741 5 // Revised: January, 2014
Fuzball 0:9cfce382e741 6 // Desc: Commands, fonts, and class for using a
Fuzball 0:9cfce382e741 7 // Nokia 5110 LCD via the Phillips 8554 LCD driver.
Fuzball 0:9cfce382e741 8 //
Fuzball 0:9cfce382e741 9 // Typical Usage: User must fill the LcdPins struct with the pinout used to control the LCD and
Fuzball 0:9cfce382e741 10 // instantiate the NokiaLcd class - passing the created LcdPins struct to the constructor.
Fuzball 0:9cfce382e741 11 // The class function NokiaLcd::InitLcd may then be called to reset and start the LCD driver.
Fuzball 0:9cfce382e741 12 // A simple 6x6 font (6x8 in LCD space and ~5x5 character space) is included to facilitate
Fuzball 0:9cfce382e741 13 // the NokiaLcd::DrawChar( char character ) function, which will copy the character 8 bits
Fuzball 0:9cfce382e741 14 // at a time for 6 clock cycles.
Fuzball 0:9cfce382e741 15 // Commands may be sent to the LCD via the NokiaLcd::SendFunction(char cmd)
Fuzball 0:9cfce382e741 16 // function, but be aware that certain commands require the Function Set register's H-value
Fuzball 0:9cfce382e741 17 // to be either 1 or 0, depending on the command. This class does not check to see whether
Fuzball 0:9cfce382e741 18 // the H-value is of proper status. The Function Set register /may/ be changed via the
Fuzball 0:9cfce382e741 19 // NokiaLcd::SendFunction(char cmd), but the code uses this internally and expects that
Fuzball 0:9cfce382e741 20 // most function registers have not been changed by the user.
