My quistion to you is, don't you have 2 enable pins on you LCD?
in that case look at the repost in this trat Reply #7 from legba7


Else, tray to play with the x e.d. : x+= 0x80 ,0x14 0x54

I don't have your LCD so i can't try.

Good luck, and let us no if it works and with what values.

Hi,

I put my library online at:
http://www.ineonline.nl/download/LCD4Bit.zip

Good luck.

you forgot to show your error, but maybe this helps. I had errors to when compiling. The reason was that i had more liberies to control the lcd in the libary directory that use the same files.
Try to tempery move other libs and try again.

I hope this hepls you.

I changed the origenal 4bit library code my self to let it work with my 4x20LCD, KS0066u Based.
I got it working perfectly.
Below the code for those of you who have the same LCD.

LCD4Bit.cpp:
changes i made
just replace the origenal ones with this ones.


The new constructor:

LCD4Bit::LCD4Bit (int num_lines) {
  g_num_lines = num_lines;
  if (g_num_lines < 1)
  {
    g_num_lines = 1;
  }
  if (g_num_lines > 4)
  {
    g_num_lines = 4;
  }
}



function cursorTo

void LCD4Bit::cursorTo(int line_num, int x){
  //first, put cursor home
  commandWrite(CMD_HOME);
  if (x>19)
  {
        x=19;
  }
switch (line_num)
  {
 case 1:
    x+=0x00 ; break;
  case 2:
    x+= 0x40 ; break;
  case 3:
    x+= 0x14 ; break; // In fact, line 3 is an extension of the line 1 (beyond the 20 first characters)
  case 4:
    x+= 0x54 ; break; // Line 4 is an extension of line 2
  }
  //
  commandWrite(0x80+x);
}


Test program:

#include <LCD4Bit.h>
LCD4Bit lcd = LCD4Bit(4);

void setup() {
  pinMode(13, OUTPUT);  //we'll use the debug LED to output a heartbeat
  lcd.init();
}

void loop() {  
  digitalWrite(13, HIGH);  //light the debug LED
  lcd.clear();
  lcd.cursorTo(1,0);
  lcd.printIn("Line 1");
  lcd.cursorTo(2,0);
  lcd.printIn("Line 2");
  lcd.cursorTo(3,0);
  lcd.printIn("Line 3");
  lcd.cursorTo(4,0);
  lcd.printIn("Line 4");
  delay(1000);
  digitalWrite(13, LOW);  //clear the debug LED
 }



Hope it works for you to!

The link http://lutingaia.free.fr/LCD4Bit.zip returns an error for me  :'(

Does anyone know where I can get hold of this library?

Thanks

I have the same problem. How has the zip for me?

Tanks a lot!
9  Forum 2005-2010 (read only) / Interfacing / witch oscilloscope to buy on: August 19, 2008, 07:26:12 am
I want to buy a scope and need to know how quick it must be. The Arduino runs on 16 MHz.
5MHz Pc Oscilloscope, 10MHz Pc Oscilloscope or 25MHz Pc Oscilloscope. (PicoScope)
The prize dif is more then 150 euro's.

I wil use it to measure inputsignals from e.g. 433MHz reciever.
