Hello,
I have never used it, but if you want to laern first buy it!
and then do research on it then will work!

How long is your display?
Will you use mobile Bluetooth some sort of application or what?

The easy way to go https://www.adafruit.com/products/1588 just hook up to your pic micro and change the data to load serially.
