LCD display with Driver

Hi All,

I am brand new to Ardunio as of today so please be gental with me.

I have an LCD display with a driver circuit already attached. It has 3 pins Gnd, +5v and Serial. I have used this before with a pic a few years ago and I know it worked. How do I connect my Arduino Mega to the serial connector and send data?

Thanks for any help


Unfortunately there is no standard protocol for the various serial LCD implementations. You will have to determine which one you have. The 'driver circuit' is frequently a PIC running code by phanderson so I would start at his website


If it's the Sparkfun one then all the code is on the website.
