I think I'd avoid the RAM-gobbling strings like "Commenced device-under-test debugging!" (see the comment about candles and gas leaks), but yes, a useful technique.

How long have you got to perform the operations, and how secure does it have to be?
And why is this a poll?
17583  Using Arduino / Programming Questions / Re: Continually re-entering setup() on: December 04, 2011, 03:52:01 am
Be very, very careful with debug prints however; someone here recently pointed out that they can be akin to looking for a gas leak with a candle.

You could invert your analogWrite with a simple subtraction

Public Address or Personal Assistant?
17586  Using Arduino / Programming Questions / Re: PING in Assembly on: December 03, 2011, 05:48:15 pm
No, you're running it at 16MHz.
Big difference.

You may be lost, but brookshiresoftware doesn't know its PPM from its PWM.

Don't believe everything you read on the Web.
No, wait...

How's that 99% looking now?

The way it works is, you tell us what you have already tried, what problems you had, how your robot is wired, what your robot geometry is, and then we try to help.
Otherwise, it looks like we're doing your work for you, and that would be no fun for you.

I only got got 58000 hits with google "iliffe vector c"

Post your code and the errors you're getting
17591  Using Arduino / Programming Questions / Re: trouble creating multidimensional array on: December 03, 2011, 01:50:49 pm
Iliffe vectors
17592  Using Arduino / Programming Questions / Re: Variables in switch statements on: December 03, 2011, 01:47:38 pm
You should only use a variable in a switch.
What would be the point of using a constant?
You'd always know which case it would select, and so would be pretty pointless.
A case must be a compile time constant.

Your case could use a lookup to change which code it selected.

The receiver makes a PWM signal for each channel (receiver output to esc, servo's and my attiny) from the PPM signal (receiver input).
Servos typically use PPM as their input, as do ESCs.
It simplifies the decoder in the receiver.
Your setup may be an exception.
17594  Using Arduino / Sensors / Re: how to read PWM signal from RC receiver on: December 03, 2011, 11:48:22 am
Your R/C receiver almost certainly outputs PPM, not PWM.
The distinction is a fine one, but searching for PPM instead of PWM could yield better results.

I not only said what the application was. but I posted the data specification
Classic noob mistake - asking how you think something should be done, not what it is you want to do.
It took quite some time before I associated the data conversion problem posed in this thread

with the micrometer mentioned in
