Satellite receiver is a little receiver which comes with the HK TXs. I think I removed them from your kit as extra parts confuse people. It needs a fair bit of software to work but its basically an extra receiver.

Thanks.
Do you know of a site with good beginners programing information? _________________ So even the rain that falls isn't actually going to fill our dams and our river systems
I started writing this months and months ago as an extra resource for a subject I am tutoring. Its on programming in assembly. But this may just be more confusing. I would try doing a few things just on PC in python/C/C++ to start off with leave the embedded once you have a bit of a grasp of how things work.
^^It hasn't been proof read and is no where near finished. Also assembly is really very low level and unnecessary in 90% of applications today. _________________ Steven Martin

Ok well I think I have my head around the satellite RX code. There is a fair bit of bit banging which may get pretty interesting as I don't have a scope......
I have a some sample code which is for an Arduino Mega. The B-328 is sorta Arduino compatible so I could finish off / port code in Arduino or I could port it to C. Or even assembly if anyone wants to do some crazy stuff which needs ultra fast code.
Does anyone have any preference ATM I am thinking of porting to C. But if people would prefer it in the simpler Arduino coding format I can leave it there and just finish/fix it for B-328.

I'm still old school radio stuff here so what is this satellite Rx? I am Interested in getting rid of the slow 50Hz servo pulses and have been working on my own 2.4GHz system but can't afford PCB prototyping at the moment. _________________ Get Some!!!

I wish I had known about them 20 years ago when I started making proto's with wire-wrap wire by hand. You need good short-range eyesight (or a magnifying lamp) and a steady hand, but with one of these, some donut-ring perf board (Jaycar, Dick Smith) you can knock up (and easily change) a prototype in no time. You only go to etch-PCB's once the design is finalised
Available in Aus (and the spools of wire) from Farnell for about $20, or make your own out of a standard CLick-LeaD Pencil and some bent coathangers. _________________ Great minds discuss ideas. Average minds discuss events. Small minds discuss people

Assuming you are asking because you intend to give out the code once you make it, I would like the Baby O to mix two servo signals with a logarithmic response and the ability to use a nano gyro. I would not presume to talk about codes. _________________ So even the rain that falls isn't actually going to fill our dams and our river systems

PM Dumhed, he has a PCB router that can make up boards from Eagle/Protel files for good prices. _________________ https://www.halfdonethings.com/
Mixing is the easy part. Nano Gyro I have no idea about. Is this an RC product or am I adding a gyro to the chip. Can be done and I am interested but need a bit more info.
Hard part atm is interfacing with the Satellite RX form the hobbyking radios. Once that is up and running should be easy.

Why must they hide these things. I was looking for that for ages lastnight.
Well should be pretty simple once I get serial setup so I can debug it.
Will keep you updated on progress _________________ Steven Martin

Hmmm I am not 100% sure how gyros work in the RC work. I assume its meant for tail rotor of heli and just runs some PID loop to keep angular rate to ~0. If so what you could do is apply a constant 1.5ms signal and then read in the output signal and use that to determine your spin rate.
However I am not sure how well it would work on the little ants and is it really necessary?
In any case I can play with it if you want it but it might be easier to get a dedicated gyro sensor rather than trying to work with RC stuff as we aren't actually generating RC signals digital data is read straight in from the satellite receiver. e.g.
