7-Zip operates with the 7z archive format, but can read and write several other archive formats.
The following definitions allow you to access the appropriate bits of the PIN registers that the switches connect to.Free/Open Source Alternatives Software Nameħ-Zip is an open source file archiver. The LCDInit function also initialises the IO pins that the three switches are attached to with pullups enabled. The font size can be specified with the following definitions: #define SMALL 0 Note if the string exceeds the width of the display it is truncated. Void LCDPutStr( char *pString, int x, int y, int Size, int fColor, int bColor) Writes a string of ASCII characters on the display. The colour of the character is defined by the fColor and the background around the character by bColor Void LCDPutChar( char c, int x, int y, int size, int fColor, int bColor) Writes a single ASCII character on the display. Void LCDPrintLogo(void) Prints the Sparkfun logo Void LCD7Seg( int x0, int y0, char character, int color, int bgcolor) Emulates a seven segment display Void LCDSetCircle( int x0, int y0, int radius, int color) Draws a circle Void LCDSetRect( int x0, int y0, int x1, int y1, unsigned char fill, int color) Draws a rectangle Void LCDSetLine( int x0, int y0, int x1, int y1, int color) Draws a line from (x0,y0) to (x1,y1) Void LCDSetPixel( int x, int y, int color) Sets the colour of a single pixel Void LCDClear( int color) Used to paint the whole display a single colour you can use the following predefined 12 bit colours definitions: #define WHITE 0xFFF The default orientation after using LCDInit is such that the three switches are at the bottom of the screen Void LCDOrientation( char orient) Used to rotate the orientation of the display with the following definitions #define STRAIGHT 0 Void LCDInit(void) This must be called first to initialise the display The module provides the following functions: Define LCD receiver chip (Philips Black connector, Epson Green connector) For more information about why you may need to do this is available here. #define MEGA // Use if using the Arduino MEGA boardĭepending the supplier of the LCD screen you may also need to toggle the comments on the next two lines as well. #define UNO // Use if using the Arduino UNO board Define Arduino Target board (Comment out) To define the Arduino board simply comment and uncomment the lines shown below at the top of the Color_LCD_driver.h header file
Lynch’s excellent tutorial.ĭownload Color LCD driver C source code zip file
This code is based on the code provided in James P. I have developed a software driver module for this in C that works for both the UNO and MEGA boards. The screen is 132×132 pixels and supports 12bit RGB colour. The shield also includes three push button switches. The Sparkfun Color LCD Shield, shown right, provides a straightforward way to add a display to the Arduino UNO or MEGA boards.
