Do you want to manually override and drive the motor when the autopilot is engaged?
I did't expect the autopilot to do anything when not engaged/standby ...
It is working manual like you said....... it engages the clutch and stears right/left ....
I´m still fighting with with my old NECO 24V drive. Manualy it works, but the IMU/compass values
start moving/fading (irrational) when the drive runs (5 meters distance). I guess this could be due to electromagnetic noise by the drive/brushes. I will first will try to change the connection btw. Pi and Nano to USB (right now it is
5V/GND/TX/TX-Pins) and if this does not help y will start cheching the drive for flyback diodes and capacitors to reduce noise.
For now I use a simple H-Bridge consisting of two of the cheap chinese relays and a other relay for the cluch.
Are there any other suggestions ?
Is it possible to use an other compass source , NMEA or my old Simrad/Robertson RF35 ?
I´m having good fun with this project and learnig a lot.
Thank you verry much.
Save sailing to all and greetings from Spain
