I'm totally new to this Arduino. My only experience in programming was when I took the introduction to C++ last year. I do have Arduino UNO and LCD and I have tested it already. I used the LCD library, and my LCD is working properly with the 4bits. I kinda understand what the library is doing. My problem is how to initialize the LCD without including the .h. Can I do this?
int d7Pin = 7;
int d6Pin = 6;
int d5Pin = 5;
int d4Pin = 4;
int enPin = 3;
int rsPin = 2;
void setup()
{
pinMode(d7Pin, OUTPUT);
pinMode(d6Pin, OUTPUT);
pinMode(d5Pin, OUTPUT);
pinMode(d4Pin, OUTPUT);
pinMode(enPin, OUTPUT);
pinMode(rsPin, OUTPUT);
}
