About Me:

I work as an embedded programmer primarily with the ARM Cortex-M3, but also quite a bit for the AVR. I also like to program during my free time, but more PC oriented than work, mostly C++/Qt and some Java (for Android). I tend to have lots of projects in progress without really finishing any of them, which is something I'm currently trying to change. I use Arch Linux as my primary operating system since 2008.


Please tell us a bit about your UAV interest

I started out flying homebuilt Depron planes and then moved on to larger EPP and some ARF balsa planes. I also got a few helicopters but I'm still not that good at flying those, I manage fine as long as it's in the normal orientation but no inverted 3D madness. This continued on for a few years until I got my job as an embedded programmer, which got me more interested in different applications for microcontrollers. That naturally lead me to wanting to combine it with my hobby somehow and that's when I discovered the ArduPilot. About a year ago (beginning/mid 2012) I got my first APM 2.5 used from a guy on a Swedish forum.

"Yeah Andy, my comment wasn't directed at you. The product you linked seems fairly similar to that adapter I'm using, only with more ports and an MCU, and no 3.3V regulator. I'm only building a EPP plane so I should be fine with 2 satellites. :)"

"Hi Sam,
The adapter in the picture is not doing any PPM conversion, it's just a regulator with some logic chips that switches the signal between the two satellites if one should lose the signal without requiring an MCU.

As you can see in the code I…"

I have submitted a pull request https://github.com/diydrones/ardupilot/pull/520 that adds Spektrum satellite support to the APM2.0/2.5. I know this was possible with the old APM1 and I've seen some people requesting this for the new APM.I have…
