Hi everyone. As part of a project, I need to interface many PICs to an original intel mother board so that data can flow between the PICs and my pentium 4 processor. I think I will use a PCI card but I am not sure how to deal with the difference in operating frequencies between the 'fast' mother board and the 'slow' PICs. I think I am going to use the serial port in the PICs but do I need to use external buffers and FIFOs? Has this been done before? Thanks.
