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

[keviltran]

Anyone can help pls

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 !

You would be better off looking for a C forum which I think is your programming language - this is for Melabs Picbasic language.
