Hi. Im new to the pic and find this list a valuable resource - thanks everybody! Anyway, Im hoping somebody can point me towards some kind of resource on the net which would help me understand how to use SPI mode on a 16Cxx. Im at the coding stage, with a pic talking to an ISD sound chip. However this would apply for any slave SPI device. (With the pic in master mode).
