it's just a problem about writing a DAC driver

if u use a serial DAC,the task will be a little trouble
if u use a parallel DAC,u just give the DAC a clock and the data,then the DAC can work

i want to send the digital data to power amplifier.so i have to convert the digital data to analog using D/A technique. but i dont have any idea how to start with D/A in sparten 3e. the sparten 3e used SPI for D/A.i need some tips and help here.

the keypoint is quite clear.
u just need to write a SPI driver for the DAC,then the DAC can work!
So,just refer to the DAC's datasheet,find the control timing,implement the timing sequence
by ur code!
