I'm glad you like it It is just a mockup, it doesn't do anything and has not been integrated to the mpguino codebase, but here is the code if you are interested. I basically build the numbers with 5 custom block shaped characters (will need to get rid of the current custom characters for this)

PHP Code:

//GPL Software  

byte brightness[]={0,42,85,128}; //middle button cycles through these brightness settings    
#define brightnessLength (sizeof(brightness)/sizeof(byte)) //array size    
byte brightnessIdx=2;    
#define contrast 15    

//LCD Pins    
#define DIPin 4 // register select RS    
#define DB4Pin 7     
#define DB5Pin 8     
#define DB6Pin 12     
#define DB7Pin 13
