Work as an engineer on a offshore construction and ROW vessel.
Please tell us a bit about your UAV interest
My interest for UAVs started when i was googleing for autopilot systems for my RC helis. I found this site, started to read, and i was hooked.

"Will this new board support the new Dshot protocol?
advantages compared to the most used analog signals like PWM as also oneshot125 or 42 are:- no signal jitter.. if the FC sends 1375 the ESC will receive 1375 - high resolution (2048steps)- no…"

"braker. it is not a wide hole, because all professional developers know how easy it is.
If someone comes up with some revolutionaries code, they can write them in native language, and then they can keep them secret a little longer.

"I agree that i shouldn't be so easy, but many people think it is a bigger problem than it really is..
All software can be reversed, native code just takes longer time.
So if you want to protect some secret licensing algorithms and keys, the you can…"

"You can run the hex through a AVR disassembler. Then you got assembly code. Unfortunately converting the assembly code to C is the big problem here."
"Thank you for the information. This is called cascade control.
Maybe someone can update the wiki?"

"Have had a look at the code.
Looks like the D values from the "Configurator stable mode page" is saved in the STABLE_MODE_KP_RATE_XXXX variable.
Eks from the code:
control_roll = STABLE_MODE_KP_RATE_ROLL*err_roll;
And we all now that zero in…"

"Have the same problem. When i set D=0 in stable mode, the quad flips backwards, no oscilliations."
Wanted to share my first Arducopter flight with you. As you can see it needs some tuning. Stable mode is getting better after a little tuning :)Can anyone suggest some starting values for PID tuning in acro and also stable mode?Quad weight is 750…
