Aleksey has mentioned that he has an alexmos firmware update that supports MAVlink as a means of avoiding/eliminating sensor drift by leveraging flight controller attitude and GPS.
Randy had mentioned "alexmos serial" support during the APM 3.3 beta period, but eventually transitioned to StoRM32, for which serial and later MAVlink integration was added. Is the serial support a mapping to the Serial 4/5 port on a Pixhawk, or something else (digital AUX pin)?
I happen to be a fan of alexmos, so I am hoping to connect the dots here, and I am happy to contribute pull requests, technology, or documentation (sometimes the most rare and valuable commodity) to help make it happen. I would like to be able to use "point camera here" region of interest in auto missions with an alexmos gimbal. Does anyone know if it is or was ever possible? Randy mentioned it was there but had not been tested, but it's not clear to me as an engineer how it's possible to implement something without any testing or verification whatsoever. Then that is the last indication I have found mentioning alexmos.
Why do I like alexmos? It was the first DIY-friendly controller to support encoders, and it happens to power my favorite gimbal (HD Air Studio InfinityMR). Not only that, I see Basecam continuing to expand their offerings with the new "extended" (CANbus IMU's!) and "pro" boards.
Can anyone give me the lay of the land for where we stand today? Then I will dig into the source to see if I can make sense of the state of things to figure out where we go from here.
