Larry, 1) most people on this list will prefer plain-text only, and indeed some mail clients to not handle the multi-part messages very gracefully. 2) your client (or maybe server) keeps garbling the subject line with some business about spam filtering. That's really obnoxious. About your problem, how about just using a hardware timer to measure the pulse width? In your main loop, just do your menu management stuff, if you detect an interrupt on the line that you're measuring the pulse on, just start a counter, then wait for another interrupt to stop it. Of course that's subject to some limitations in terms of measurement length, but you can work around those fairly easily I'd say. - Marcel On Fri, Dec 19, 2008 at 10:01 AM, Larry Bradley wrote: > Olin: > > Interesting.
