I would suggest that fred is pretty much right on the mark with his
suggestions of windows being the problem with DLM.
I have noticed that:
After using a full sized dos session and turning off emulating screen calls
I get fewer errors, unless,
1) I have another COM port in use
2) I have started almost any windows program from the dos session that
Previously opened the COM port that my MiniBoard uses, and,
3) Have not closed those programs, and,
4) I have not adequetly prayed to the god of silicon because the above only
works ninety percent of the time.
The rest of the time requires either a
powerdown or hard shutdown. I have not bothered to figure out which. When
I start working on a lot of debugging I now boot to dos. It's a lot less
frustrating and I dont concern myself as much with how many times I have
been trying to write to the eeprom unsuccessfully.
Meanwhile, I have wired the A port ground pins to the miniboard ground and
the ground of a second power supply. I have wired the +5 pin to the external
power supply (without attaching it to the miniboard power) and solved the
servo problems resetting the miniboard. I guess it always helps to give the
control signal a ground back to the miniboard.
I sledgehammered the HexMon/ServoMon code into the Imagecraft compiler
miniboard library. Of course I made some rather silly errors and watched the
servo go into fits.
Old radios and tape decks I had have supplied many nuts and bolts to add to
my parts bins.
I picked up three poloroid cameras the other day (1.79 each) and had great fun
ripping them apart. Looks like a great source for not only motors but for gears
and springs as well. Now I am keeping an eye open for a poloroid with
automatic rangefinder.
My children have hidden all their RC cars. They didn't like the way I was eyeing
them....
