I'm working on a project to use APM to teach teens RC flight. Rather than go the buddy-box route, I was hoping to use a joystick/laptop along with geofencing. What I'm trying to figure out is how if at all, I can take back control from the joystick if I'm the one holding the Tx, without having to fiddle with the laptop.
It's easy. Just switch back into manual mode with your RC toggle. Joystick control only works in auto modes.
That's what I thought as well, however I don't seem to have any control unless I disable the joystick in the mission planner. The plane just dives out of control with no control from either control device when switched to manual.
APM 1 or APM 2?
Right now I'm working on an APM1 1280 HIL only (no IMU). Everything works great, modes change and I can enable/disable geo fencing from the Tx. I just can't take manual control *if* something were to go wrong.
My 2560 is in my Tri and my APM2 is still somewhere in transit.
Are you saying that when you switch into RC manual you don't get RC control? That seems very unlikely, since APM 1 has a hardware multiplexor. What you're seeing is just an artifact of the HIL version, which bypasses the real hardware outputs. Put it on a real plane with the IMU shield and I think you'll find it works fine (test on the ground first!).
That's exactly what I'm saying.
I'll check it out when my APM2 arrives and I can move the 2560 to a plane.
Yes, just an HIL artifact.
