[Help] PIC 16F886 with 9 button program with CCS

Anyone can help pls

Quote:

Hi all. I'm a newbie in PIC and i do this project

Input :

Port A0-A5
Port C0-C2

Output :

PortB

When i push a button form 1-9 Pic will output random on PortB. This is program i have written. I have simulation on Proteus, it working but sometime when i push button, output is blinking, not constant. Is there wrong in this program?

And when I download program to real chip PIC 16F886, it not working. Pls help me make good and clear program. Many thanks !
