An interesting hardware bug
Posted: Tue Jan 29, 2019 8:51 pm
I was debugging my new attitude controller with CF2 on my table and removed the propellers for safety reason. But the communication between the CF2.0 and the client is very bad, and the link quality is less than 50% when the motors were running without propellers on it. At beginning, I though this may be due to the fact that my new attitude controller consumes too much CPU resources and could not spare any more for the communication.
However, when I put back the propellers and ran the controller with propeller spinning, the communication quality goes back to normal again. I did not expect that whether the propellers are mounted or not when the motors are spinning can impact the communication quality. No sure if this is related to motor back emf which might impact the circuit.
