spi with dspic chips

Your DAC chip only has a SPI port to receive data on, so you must send the data in the SPI convention.

Many smaller pic chips do not have a hardware SPI port, but they can still communicate with a SPI device by software control, commonly called ' bit banging '.

A few searches of the forums should find you some code to work from that can adapt to a dspic.
