On a different subject re F88: I have need of a low-end DAC, and I am buffering RA2 with a buffer-follower so it won't be swamped. What I am wondering is: can I have A/D conversions on RA0 and RA1 (not using the comparator at all) while using VRCON's VREF output onn RA2? Looking at the I/O port schematic of RA2 it would appear so, but does anybody know? F88 is a new one to me. --Bob -- Replier: Most attachments rejected -------------- Bob Axtell PIC Hardware & Firmware Dev http://beam.to/baxtell 1-520-219-2363 -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
