PIC 16F88, Olimex PG4-D, Newbie problems... > Set of sample programs for the 16F88? 16F877A (which I'm going to > stick on an Olimex P40-B)? Ralph I should have caught this one earlier, too. The 16F84A programs almost identially to the 16F84. However, the 16F877A programs entirely differently than the 16F877, so don't get caught in the same problem when you move to that chip. There are a handful of different programming algorithms, but basically the older parts program one word at a time. For larger memories this gets slow. So on the newer parts, they are programmed four words at a time. The 88 and 877A are this way, but the 84A and 877 are not. A lot of the older programming software only knows the old way. There actually is a tiny difference in programming between the 84 and the 84A, but it's so tiny that a programmer would have to work hard to write software that would work on one and not the other. But the difference between the 877 and the 877A is night and day. --McD _______________________________________________ http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
