SPI, available with or without i/f level circuitry. Fairly easy to use. I only have issues with the really truly weird IRQ handling. ( If I recall correctly the IRQ pin behaved very strange, i.e if an byte was received *during* spi comms it was never re-set and one had to 'manually' check for the 'condition, as the (pic)irq was never triggered in this case ) Anyway, apart from that issue,work as charm ( well kinda :) ) /Tony -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
