Dear sir
Anybody Please help at the earliest
I am working as a lecturer and I am using 16f877 pic mictrocontroller development kit where portb4:7 are connected to rows and PortE0:2 are connected to column. I request everybody to please give the Code in Hi-Tech C for teh matrix keboard recognition and display with wake up on key stroke(Sleep mode ) and the key identification in an array form. Also I request for a sample code to generate alarm using Timer0 on interrupt. I require this code very badly at the earliest for my student's final year project work. Please help me.

Thanking you
