I'm not too adventurous, in the meantime I found a couple of nice examples. In this piece of code, depending of the status of MPD (if there's a song currently played), the code print 'system' info (e.g. IP Address, Temperature, other stuff) or song info (retrieving them from MPD, including timing and other stuff).
The only problem that I have to check, is that the example is made for a 4 lines LCD Display. I'm not sure if the LCD_Init function below is valid also for 16x2 Display ...
