saper kat sini pakar psal c programming bag pic. aku ada buat project psal multiple input using spi communication via pic16f887a.Aku stuck bila nak extend i/0
kat bwah nie ada penjelasan pasal project nie
The shift register chain
How it works
A block diagram of the shift register chain is shown below:

The shift register chain is made up of a number of output shift register devices (74HC595 or 74HC4094s) and a number of input shift register devices (74HC165). Both these chips are 8-bits wide, so the number of inputs and outputs available will be a multiple of 8. Only as many devices as are required may be fitted.
