1. Serial data inside PIC depends how do you shift it in..MSB or LSB first...you should check your ADC datasheet what it requires (which means do some homework ;o)
2. Why don't you download application note from Microchips website? Called AN526!!!!
3. There is no LCD display, only LC display!!! (o;
This depends which LCD module you intend to use...but most of them have good datasheets with example routines how to do it...
1.- My A/D converter shift first LSB to MSB bits....
2.- Rigth now i´m downloading AN526 to review it...
3.- I have JHD162 LCD module, 16X2 with led/backlight, samsung controlled based (similar about hitachi)
I had think something about shift LSb or MSB, and shift it in the PIC FILE XXX.....next make a decimal conversion to display it in a LCD...
I hope to have good experince about this....i´m expectanting ....
