Hola People, I am looking for a document or website with info on it that will tell me how to hookup an 8 bit data bus with an address bus and control bus using a PIC MCU. Im hoping to use a PIC16F84A to do this with PortA as the address/control bus and port B as the data bus. I would like to ability to control up to 8 devices using the bus by simlpy connecting them to the bus, much the same way as you would with an Device Card in an ISA bus on a 'old school' PC. Any ideas on this would be of great help... Many thanks... -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.
