Im trying to make this LCD work (BT96040AV1-I2C), im using the evaluation kit of MAXIM TINI DS80C400, it has a I2C protocol implemented, the adress that i use for the LCD is 0x78, but because of the way that my I2C class works i have to shift it right, making it 0x3C, the code used is java, i tried to implement killertoffy C code (from another topic of this forum) to java....every time i make the CheckersBoard command, the LCD gets stuck, and doesnt acknowledge any more commands.....can anyone help? or has anyone ever maked this LCD to work?
import com.dalsemi.system.*;
public class I2CBoot {
final static byte command=(byte)0x80;
final static byte data =(byte)0x40;
final static byte page0 =(byte)0x00;
final static byte page1 =(byte)0x01;
//page 0 commands
final static byte read =(byte)0x00;
final static byte funcSet=(byte)0x24; //Set function with PD=1
final static byte funcSeton=(byte)0x20; //Set function with PD=0
final static byte blankM=(byte)0x01;
final static byte scroll=(byte)0x02;
final static byte vlcd =(byte)0x04;
final static byte dMode =(byte)0x08;
final static byte setCP =(byte)0x10;
final static byte ramY =(byte)0x40;
final static byte ramX =(byte)0x80;
//page 1 commands
final static byte checker =(byte)0x01;
final static byte tempC =(byte)0x04;
final static byte biasR =(byte)0x10;
//other required variables and objects
static byte dados [] = new byte [3000];
static byte instru [] = new byte [1];
static byte def [] = new byte [1];
static byte cmd [] = new byte [1];
static I2CPort port = new I2CPort();
static BitPort resetLCD;
public static void main (String[]args){
def [0] = 0;
for (int i=0;i
The output to this code is...
