> Do you think there's a better approach to the problem? That depends.. Are you exposed to large E-fields? I had a system that I designed with a 100k pullup on /RESET, where the system worked fine for us, but the customers were having problems. When you're standing in a vegas casino, in the winter, on that carpeting by VanDeGraff and Marx, the E-fields are enormous. I watched one reset when a woman walked by at about 4' distance. Her fur coat was a total puffball. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
