I have been trying to get the above display working for days now. I have managed to use the demo python code with good effect. If I try to use lcdproc and mpdlcd to output the display of volumio web shows and MP3 files.
So far I have tested the display with the sunfounder python code from their site - got the display working fine.
I have tried both the original HD44780 driver and the updated one from AndyPi. There were issues starting LCDd until I made the following changes in lcd.conf
Now the display just kicks out a line of squares and flickers violently when I play an audio track. I can see that the display is reacting to my commands but it is failing to display readable text. The last thing that I have tried is redoing the pin mapping in the lcd.conf e.g. RS,RW,E,D0-D7 etc.
Greatful of some guidance.
