Having to trouble shoot a Dell Inspiron 1100 not booting up cleanly. An alarm
goes off and it goes to safe boot mode. I am running the original Home version
of XP without updates and RoboLab 2.94. Keeping the 2007 working original
program until new application arm is working. Side arm needs to come in and heat
up surface where oil pastel dot is applied and move aside for the application
wheel to rotate to the color and move down to apply the dot. Thinking it will be
a side arm where the heating box flips down, moves into dot area for allotted
time then out. http://tomlohre.com/lego.htm

Here is the twenty foot long process on the main RCX for the printer.

I wanted to use sub routines and loop the process so the program could look
elegant but never got it to work. Here each color has it's own put and return.

I am back on the Lego wagon, making another painting machine. Looking forward to
creating the best practices program with your advising.

That's kind of what I was getting at with the motor power stuff; I can tell the
RCX can handle more motor powers, but there doesn't appear to be a way to use
them in the program...

D'oh...

I'm posting this because I'm sure I'm not the only one who missed this:  I
didn't realize there's a drop-down when BricxCC starts up, to select "Swan"
instead of "RCX" when making the first handshake with the brick.

After doing that, it compiles no problem.  MotorSetPower128 doesn't seem to
work, though...

At any rate, WaitMS() is great!  Super-precision motor control, here I come!

Thanks for the link!

The documentation on this page
http://www.elenafrancesco.org/old/lego/Firmware%20Features.html mentions the
following:

"new wait1Msec opcode to perform program waits using one millisecond resolution"

Maybe that is what you are looking for.

BrixCC doesn't recognize "wait1Msec", and when I try to download a program with
it, it just gives me an error.
