If all you want it to do is exactly the above, (i.e. take five analogue=20 voltage readings) then I would say yes, it could do that no problem. It would help to know in a little more detail what exactly the PIC will=20 be doing though. Will there be any processing of the analogue information? (what kind?=20 simple maths or more involved like e.g. FFT) You mentioned driving the various components too, will the PIC be=20 involved in this also? Will there be any other things for the PIC to do? (display, user I/O, etc) Depending on your answer, it may be worth looking at a PIC24/32/dsPIC=20 instead. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
