BACnet Plugfest Complete

Today was the final day of the BACnet Interoperability Workshop, or Plugfest as it is commonly called. Over the two and a half days we found only two bugs in the open source BACnet stack at SourceForge that I ported into our lighting panel in 5 days. I fixed both bugs in a few minutes and uploaded the firmware into the lighting panels using the in-circuit-debugger. The fixes were verified by the other vendor.

The MS/TP state machine worked. We tested it at 9600 baud, 19200 baud, and 38400 baud and worked fine. 76800 baud did not work, so I will need to figure out why. I may need to clock the processor at 40 MHz instead of 20 MHz to get some extra horsepower. I will also need to optimize the other processes, like the input reading and debouncing, to take less time in the main loop.

The food was great and I met a lot of nice folks. Hopefully my flight home tomorrow will be uneventful.

I write software for a living. So, I dedicated some web space for some stuff that I have worked on. I mostly write embedded C for PC based controllers, but I have dabbled in a few other areas as well.
