//where is a problem ?
//Code works on Proteus 8 Professional, but dont work in real.
bad project config, code or schematic ?
Write back fast

maybe I need to add cristal ?

 

You have a serious problem the way the push buttons are connected to RA0, RA1 and RA2.
You cannot connect them to one pull up resistor R9.

You need to connect the buttons to GND.
Then use individual pull up resistors, one for each of the three pins.

 

Ty... I made epic fail

 

You need the line..

CMCON =0x07;

Or the comparator module is on and portA is unaccessible..

Ty It work.
