Ok, I've created this Yahoo group for discussion and support of the OpenTracker project. The Revision 2 boards came in Monday, and I've assembled one for ...
I put the first revision 2 board in my car this morning for its first real-world test, and discovered a minor firmware bug. The tracker is supposed to...
I was wondering what sort of setup is being used for the microcontroller development - programming board, compiler (Blitzlogic + Codewarrior?), etc. I've just...
... As in 68HC11? I resurrected an old GCC port and got it working with gcc-2.95 on Linux. Another guy in France did a similar thing later bug got the whole...
Maybe I'm just confused about the Motorola part numbers. MC68HC908KX8CP is the one listed in the Parts List on Scott's site. According to the Digikey catalog,...

... 68HC was mentioned in the earlier e-mail. Wasn't sure what the person was after, as there are a lot of 68HC parts, many of them incompatible. Therefore...
... Scott's ... Right, Motorola's got three families of 8-bit MCUs, the HC05, HC08, and HC11. The HC08 is closely related to the HC05, but adds a 16-bit index...

One thing I'd love to have in a tracker, is the ability to alter the 'message' string on the fly... Why? Most HF rigs now have some form of sending the current...
... Great idea, but please don't do it in the comment field.... You will get the same junk APRS is now. There already is some sort of frequency reporting...

An updated firmware image has been posted on the website at http://n1vg.net/opentracker. This one should fix the problem with an initial position not being...
I built a unit for testing today and found that the voltage detect was stuck on zero. I finally isolated the problem to a defect in the PCB. I've uploaded a...
