Antenna Tracker on Matek F405-WING

(John Collingwood) #1

I’ve built the antenna tracker firmware for the Matek F405-WING and uploaded it to the board.

Upload seemed to go well and all the antenna tracker specific parameters are showing in the parameter tree. However, the servos don’t move. I’m not actually sure what signal pins the servos should be connected to but I tried a servo on each pin and they never moved.

Does anyone have any experience of getting the antenna tracker firmware to work with this board?

the servos wont do anything unless you have it tracking something

I’m just trying to test the servos at the moment, using the test button on the extended tuning page in Mission Planner. Just figured out the signal pin - S1 & S2 are where the signals are being outputted. How easy is it to change to S3 & S4 as S1 and 2 don’t have a 5V pin for the servo next to them whereas 3 and 4 do. I tried changing the channels in config.h but that didn’t seem to work.

you don’t need to change the code, just put tracker pitch (72) and yaw (71) on to those outputs using SERVO3_FUNCTION and SERVO4_FUNCTION.

Unfortunately, there are current Tracker versions on the firmware server only for the Navaio hardeware.
The last Pixhawk beta version is from 2016. Versions for the new boards would be great.

Flashing the new omnibus worked. First stable version of arduplane with booloader (arduplane_with_bl.hex), then follows the flashing of peters antennatracker.apj by missionplanner.

Thanks Peter @iampete . Our test setup with a omnibus works well.

Question: Is it better to mount the compass so that it tilts with pitch or better on the rotating platform that the compass only turns with yaw ?

glad to hear its working, you will have to mount the compass with with flight controller on the pitch axis, otherwise it will confuse the ekf.
