If you are using the ones like Sparkfun sells with a backpack, then I wrote some helper functions (not a library really) that I found useful. Here's the post:
Here are the helper functions (not a library really) that I use with that product:
void displayHome()
{
Serial1.write(254); // move cursor to beginning of first line
Serial1.write(128);
}
void displayMoveTo(int pos)
{
char posChar;
if (pos>=1 && pos<=16) {
posChar = char(128+pos-1);
} else if (pos>=17 && pos<=32) {
posChar = char(192+pos-17);
} else {
posChar = 128; // on error, go home
}
Serial1.write(254);
Serial1.write(posChar);
}…
I find these super useful for debugging!
