This time it was my fault 
I've just grounded all analogic pins, it look a lot better ! Now i've to try it in my boat
Edit after some tests:
The esc need to be connected to pwm and ground
All analogue pins need to be grounded, as described
Every time I flash, lock pin is back to FF, i need to rewrite it. Is it important that it's CF or FF can be added to the code ?
My esc need to be in crawler mode for full speed front and backward.
I need to uncomment the good #define to disable sensors.
pin 6 need to be connected to +5v, not sure about 3,3v.
Now, i just need to test, and then if all is ok, I will add the windvane, the sensors (temperature, shunt for current, and tension).
I will use this remote for m5stack to control it: https://github.com/PepeMax/Raymaxime-display
