I am in need of some experienced advice on using the cs4390 dac with a pic16f877. The questions are: what is the relationship between the data and data-clock signals with the LRclock and Mclock signals? Does the data have to be aligned in some way with the mclock? Does the dataClock have to be running all the time? does anyone have any code, preferably in c or assembler, that they are willing to share? any help would be greatly appreciated! thanks, raphael abrams -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
