I am creating a blower to clear away sediment by incorporating a standard thruster and ESC. I need to control the speed, so would like to map it to a joystick or a pair of buttons to increase/decrease. Any ideas on how to configure this?
This is using a Raspberry Pi 3 with a Pixhawk.
Thanks
Hi @bestglide -
This question has been answered many times! The best current advice depends on if you’re using QGC or Cockpit. If you’re just using ArduSub (4.5.3 or earlier) , you can also control the outputs on channel 9, 10 and 11 via buttons as if they are servo outputs, just like it was a gripper. You may have to increment the output signal to 1500 microseconds before the ESC initializes in this way - which is also necessary if you configure it as a lights output.
Perhaps it is best summarized here?
In any case - changes are in the works, as Eliot describes here to make this all much simpler to explain, and more intuitive to setup!
Thank you for your patience!
Mentioning lights gave me an idea. Since we are only using one light array, I have connected the thruster to a main out and defined it as Light 2 mapped to buttons for increment/decrement. This gives a reasonable range of thruster values for our current needs.
