While I do a lot of programming, saying “software engineer” isn't just a fancy way of saying “programmer”. There's a lot more to it.

It is based in Sellersville, PA. One of their retired VIPs had come up with an electronic version of the hand chime, which consisted of up to 37 battery-powered wands, each with an accelerometer and a radio, and a base with a radio and a synthesizer. text/html 2008-04-12T23:14:44-05:00 Jeffrey Nonken http://jeffrey.nonken.net/doku.php?id=ca_electronics&rev=1208056484&do=diff Real-Time Clock The project in question included an interrupt-driven real-time clock. We derived a 60 Hz interrupt from the AC input, then used that to drive a series of software counters. When we read the time from the clock variables we'd read it a second time and compare; if the results were different we'd throw the first one away and read again. text/html 2008-04-09T23:31:13-05:00 Jeffrey Nonken http://jeffrey.nonken.net/doku.php?id=start&rev=1207798273&do=diff “Programming right down to the bare metal since 1980.” My name is Jeffrey Nonken.
