Lcd Display For Ezb4 - Using Arduino Mini As Controler

Description

Hello again,

I have created an LCD Display for the EZB4.

This is a very cheep and easy project.

You will need

1 LCD display ( my code is set up for 2 line 16 char display) here are 5 of them for about 10 bucks USD

1 Arduino ( any model will work but i recomend the Pro MINI)
Here is a listing of them on ebay

Oh here is the wiring . again I am using the pro mini . this is...

Oh here is the wiring . again I am using the pro mini . this is showing and UNO board. the pin outs are the same.

To wire your LCD screen to your Arduino, connect the following pins: LCD RS pin to digital pin 12 LCD Enable pin to digital pin 11 LCD D4 pin to digital pin 5 LCD D5 pin to digital pin 4 LCD D6 pin to digital pin 3 LCD D7 pin to digital pin 2 Additionally, wire a 10K pot to +5V and GND, with it's wiper (output) to LCD screens VO pin (pin3).

Arduino code:


// LCD and Arduino to EZB4
// Project Created by Luis A. Vazquez
// www.dragontear.com

#include <LiquidCrystal.h>
String content = "";
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
void setup() {
  Serial.begin(9600);
  lcd.begin(16, 2);
  lcd.setCursor(0,0);
  lcd.print("EZB4 LCD Display");
  lcd.setCursor(0,1);
  lcd.print("By DragonTear");
}
void loop() {
  readSignalFromComp();
}

void readSignalFromComp() {
  if (Serial.available()) {
  delay(100);
  while (Serial.available() > 0) {
  int temp = Serial.read();

   
  Serial.print("Debug:");
  Serial.println(temp);  

  if (temp == 17){lcd.clear();}
      
  if (temp == 18){lcd.setCursor(0,0);}
      
  if (temp == 19){lcd.setCursor(0,1);}
    
  if (temp > 31){  lcd.write(temp);   }
    
    }
  }
}


EZ-Builder Script


UartInit(0,2,9600)
UARTWrite(0,2,17, 18, "Hello From" , 19 , "EZ-Builder")

The control codes are:

17 - to clear the screen 18 - Move cursor to line 1 19 - Move cursor to line 2

I hope this was complete and self explanitory, but if not please ask , I am willing to help.
