This is a .PDE files for Arduino/sanguino for controlling an HD74800-compatible
LCD in I2c mode using the Reprap LCD controler board.
Tested on Arduino 0011 Alpha.
Installation
--------------------------------------------------------------------------------
To install this file, just place this entire folder and point to it with the arduino
envoriment
file list
readme.txt //that is this readme file explaining how to use the I2c lcd files
i2clcd.h //this is the hex file that contains the settings for the I2c files
i2c_lcd.pde // this is the file that contains the commands that are available
to control the LCD
lcd_test.pde // this is a simple test program to test the function of your LCD
and board it uses the serial port and will show what is typed into the keyboard onto
the LCD screen it uses 19200 baud
Commands
--------------------------------------------------------------------------------
here is a list of available commands that you can use and a little bit of how to use them
LCDprint this is the command to print it would be used as follows LCDprint("start"[5]); with the 5 being the number of charitors
LCDprintIn this command will print but you will not have to call out the amount of Charitors
LCDclear this command will clear the LCD display
LCDinit this command will initilize the display
portexpanderinit this command will initilize the I2c LCD board
LCDcommandWrite this command is used to send a command to the LCD
LCDhome this command will sed the cursor to the home postion
LCDleftscroll this command will scroll the display to the left
LCDcursorTo this command will position the cursor to the position that is called out
LCDcheckbutton this command is used to scan for a button press it is displayed with a command buttonPress
Using
--------------------------------------------------------------------------------
to use these files you will need to first initilize the board and then the display
use in your "void setup()" command
Wire.begin(); //this is to start the initilize the lcd screen
portexpanderinit(); //this will initilize the board
delay(200);
LCDinit(); // this will initilize the lcd screen
delay(500);
LCDclear(); // this is a clear lcd command not needed just done to clear the display
LCDprint("start"[5]); // this is a simple test it prints start This is also not needed
then when you want to print you just add in your code
LCDprintIn("this what you would want to print");
