About Me:

I'm developing an open source autopilot for hobbyist UAVs. It's called "Flying Fox" and it's designed to be small and powerful while being reasonably cheap. This isn't a commercial project - it's an open source effort.

"I've fixed the "missing comma bug". Do an update to get the latest version. I think this addresses all the bugs you found. Please let me know about any new bugs you find."

"Jack, you said "a floating point trig library would be nice". I've just added one. It supports: sin, cos, tan, asin, acos, atan, sinh, cosh, tanh, exp, fabs, log, log10, pow and sqrt from your native maths library. You'll need to define MATH_LIBRARY…"

"Jack, I've checked in some fixes to floating point which should sort out the problems you were having with it. Let me know if you have any more problems."

"Thanks Howard. Strange. When I run "printf("test %d\n" 12);" I see:

testcomma.c:1: value not expected here

which is as it should be. This is under cygwin - but it might be a platform-dependent problem so I'll run it on my SVR-1 tonight and see if…"

"Yeah just looking at floating point right now. It's got borked at some point. I'll let you know when it's fixed.

Do you have an example of the comma problem? I haven't been able to reproduce it."

"Incidentally - picoc does support floating point (fixing a bug in it right now actually). Just make sure you don't define NO_FP in platform.h."

"Hi Jack, the "author" of picoc (being me) is still working on picoc. It's still what I'd consider "alpha" software so expect some bugs for now. Kudos to you for being ahead of the curve and using it already!

I'm still in the process of working out…"

"Hi Jack - thanks for your comments on picoc. Yes, it's still alpha quality at this stage. I'm still working on it pretty heavily but hope to reach a 1.0 release in the not too distant future."

"Nice work Jaron. Looks like a great wing. I'm planning to fly a UAV flying wing in Central Switzerland when I move there in a few weeks so maybe I'll bump into you :)"

"@Joseph: It's not quite working yet - and I'm moving country to work on autopilots commercially so I probably won't have a chance to work on it for a few weeks.

@Noth666: My general plan is to release the hardware myself. I'll make…"

"Currently I'm not using any ground station software (still working on it) but I'm planning to give "UAV Playground" a try.
