Using the Arduino IDE the F() macro or equivalent is essential to store text
strings otherwise you will run out of RAM fast.
The SD-Card Library that is part of the IDE is a memory hog too.It does not
work well on the smaller ATMEGA parts with only 2K of memory especially if you

Now that I think about this, that power drain with the M100 off is expected
I guess. Resting state of the rs232 RX line is high right?
So with the M100 turned off, the teensy is driving the line high while the
M100 is not, so it's a continuous drain from teensy to m100.
I guess I could add a DTR
Got the sleep working properly now. Goes right to 3ma right from power-up
or reset.
One last thing that isn't great about power drain is, if the teensy is
connected to the M100, and the Teensy is turned on, but the M100 is turned
OFF, then it draws 19 ma!
But it's good with the teensy on and not
Forgot to say, by adding avr/sleep.h
I think there might be other better low power libraries and examples. This
was just my first attempt.
It's not quite working right, but close. It draws 15ma on power-up until
the first command is processed, then it acts like I wanted after that. It
draws 3.3ma
I got it idling at 3.3ma. Holy crap 3.3ma!
This includes the rs232 module being powered from the Teensy.
This is with all the usb-serial code ifdef'd out, and the cpu clocked at
2Mhz.
I'm not using RTS/CTS any more either, since TS-DOS itself doesn't.

What I've seen so far is:

Neither reading or writing a file works, though TpddTool thinks writes work.

I managed to get it to run and satisfy Gary Hammond's TpddTool.py even
running at the lowest possible clock rate of 2Mhz.
At that clock rate the entire thing including the rs232/cmos tranceiver is
drawing as little as 10ma when I get sleep() working. But still only about
18ma even without sleep()

That's not bad by itself. This is roughly 1/3 of the current draw of
the M102 itself, so maybe ~33% impact on battery life with no

But even these microcontrollers are more powerful cpus and have more ram

Or just run it off an AA battery and a boost regulator. Mark Blair

Running one of the off-the-shelf simulators on a Raspberry Pi is much more
doable, but you're just slaving a much more powerful device to the M100.

Yeah, but if you're bringing an Arduino into the picture why not just build
