So I am new on the forum, I will try to respect the use, please excuse me if I do not.
I started a project of self-controled boat a few weeks ago and the fact is I have what I call a stupid problem I cannot solve. That is why I ask for your help.
Here are the data of my work :
- 2 brushless motors boat
- Radiolink equipment = Pixhawk and T8FB radio
- telemetry 433Mhz linked to my computer
- Mission Planner as ground station
I read a lot and check videos too on the Pixhawk. I think I know what I need to know and the first settings / configuration and cabling.
I set the Pixhawk, ARDUROVER mode, I did the calibrations of the compass, the radio, all is OK.
The first work was done directly plugged to the computer with the USB cable.
The radio receiver is put in S-Bus mode, channels are :
1 = AIL
2 = ELE
3 = THR
4 = RUD
1 and 2 are the right stick.
3 and 4 the left one.
In the standard use of the boat, right motor is on channel 2 and left motor on channel 3.
Then I set the servo outputs :
1 = disable
2 = right motor
3 = left motor
4 = disable
5 = RCIN 5
6 = disable
7 = disable
8 = RCIN 8
I plugged the whole components together with a DC lab power supply 12V.
First ESC is put in n.2 Main out, Second ESC in n.3 out.
I also put a small servo in n.5 out and a RC swith in n.8 out.
Then I put the telemetry to control the Pix from the boat on my computer and Mission planner.
Here is the issue.
I start the Pix, all is OK. I launch MP on the computer and connect the PIX. Still OK.
I arm the Pix, still ok. The ESC’s start, beeping is correct. I perform motor test, still OK.
Motor testing is still OK. But, I have no control on the motors with the radio. What is wrong?
On all videos I saw, it is possible to control the RC boat / plane / quadri with the radio before making a plan.
I have perform a lot of tests. The only thing I see important, if I put RCIN 2 and RCIN 3 in place of left or right motor in the servo output settings, I can control the motors with the radio but motor test in MP fails.
Then I have other question. The servo and RC swith does not work too. I read in the PIX doc I should put an UBEC 5V power in the AUX OUT so that current will make servo and other components work. But in a video I saw there was told not to put 2 power entries inside the PIX (power module + BEC or UBEC).
What about this fact? How can I make my components work?
If I put component directly on channel 5 and 8 of my receiver it makes the PIX disarmed…
I searched solutions on the Internet, but nothing is clear, I think it is time for me to talk about with some people to have advices.
Thank you in advance for your help!
