Step 1

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 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:

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

Code:


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.
