Thanks for the heads up. I don't know anything yet about bit banging but guess what. A whole new ball game just opened up LOl. Sorry not interested in the ATMEL. I may be what I need in a 40 pin but I will just go to a plcc type and use a pic. I can use some of i/o pins for other uses as well. -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
