Electronics » spartan 2 config with a PIC & SPI serial EEPROM..

This is an update of my previous PIC-based FPGA configuration solution. In this version, larger and faster SPI EEPROMs are used with a PIC 16F628 - the extra IO ports allow two FPGAs to configured from the same EEPROM if required. The source code can easily be adapted to other PICs (EG: using a 16F627 would save a few pence:)

I wont go into great detail here, there's source with full info and a schematic in the archive. If you need a simple DOS-based 25XXX SPI EEPROM programmer, try my own here
