Hello everyone,
I want to drive a 7-seg. display, using TPIC6B595N and pic16f877 on my picdem 2+. I don't know how to generate clock pulses by using one of these RB5 For SRCLK, RB6 for RCK and RB7 for serial in. Any idea is appreciated.

here is the datasheet for TPIC6B595N

thank you very much.

This chip has the same interface as a 74595. Do a web search for
that number, and also for 74HC595, etc. There are lots of sample
projects available on the net.

Also, CCS has a driver:
c:\program files\picc\drivers\74595.c
They don't say so, but I think they intend that you connect SRCLK
and RCLK together. The data sheet refers to this, and the CCS driver
only has one clock signal.

You may found here an example for that chip:
