SPI PIC interface for 8 x 7Segments Display

[AlbertoFS]

This is a SPI interface for an 8 digits x 7 segment display. This interface receives 8 bytes and places them in the corresponding digits. This interface is completely transparent.
The PIC master performs all the cooking of the values to be transmitted.
The code is very secure, as it has 9 error checks that can be seen on the display. What will help in making your application.
The demo has 2 PICs, one for the master and one for the slave, connected by a hardware SPI bus.
For code loading reasons Proteus must work with a 8Mhz clock only. SPI transmission consumes a lot of resources.
All options are configurable.
