Sparkfun Serial LCD 2.5 3.3V White on Black

Hi guys, I purchased this:

I am trying to disable the splash screen, but dont quite get what else Im supposed to do. I have the serial wire tied to pin 2 of the arduino. Here is the code I used.

void setup(){
 Serial.begin(9600);
}

void loop(){
 Serial.print(0x7C, BYTE); 
 Serial.print(0x09, BYTE);  
 
}

Do you mean arduino pin 1? Pins 0 and 1 are hardware serial port on arduino, not pin 2.

Plus, I suggest you do a delay before you send the bytes and send them in setup instead of loop.

LoL Thanks!

I was using the softwareserial.h on another screen using digitalpin 2 like what was suggested on this page: Arduino Playground - SparkFunSerLCD

gonna switch it to 1, add delay, and move it setup. Thanks!!!

So after liudr's help, just plug the serial connection to digitalpin 0 and this code worked perfectly. Thanks again!

// make sure serial wire is connect to digitalpin 0


void setup(){
 Serial.begin(9600);
 delay(500);
 Serial.print(0x7C, BYTE); 
 Serial.print(0x09, BYTE);  
}

void loop(){

 
}

You're welcome. Can I ask you what type of project you're using the display for?

BTW, the softserial is obsolete and you should get much better results with newSoftSerial:

I dont have a specific project right now. I just always to learn how to use an LCD. LCD's just look cool! 8) But thank you for your help. Im gonna have a look at the new software serial link you provided

You're welcome! I use lcd mostly for interactive projects where you can enter parameters of select from menus or lists. If you have more questions, just post another thread.

BTW, your lcd is 3.3V so do you have a 3.3V arduino?
