how to configure more than 25 pin in pic16f877a for spi data
PostPosted: Sat Aug 23, 2008 4:40 am     Reply with quote
hi friends

I want to configure more than 25 pins in pic16f877a for spi data out, because i am using 25 shift registers that are connected to 25 pins in pic16f877a. I am using same clock and output enable for all shift registers. In pic total 33 i/o pins and I am using two pins for clock and output enable. Can we configure rest of these 31 pins for spi data write ? Please help me to solve this problem.
