Oneshot42 Explained - KISS ESC/FC Protocol
#1
Oscar has covered Oneshot 125 and Multishot, but there doesn't seem to be much info around Oneshot 42 so I will try to fill the gap here with my limited experience.

Some background before we move on:

OneShot125 is basically an alternative PWM signal from the ESC to the motors. Its 8 times faster than the standard PWM signal. Available on most SimonK, BLHeli and old KISS ESCs. 
Multishot is 10 times faster than Oneshot125, and 80 times faster than standard PWM.

There is nothing secret on oneshot42, it's similar to Oneshot125, but the speed is somewhere in the middle of the other 2 protocols, being just 3 times faster than the OneShot125. It's developed by Flyduino for the KISS ESC and FC.

Its the same as oneshot 125 just another 3 times faster.


Oneshot 42 still has fully 1000 steps of resolution as it uses a 24mhz timer on the ESC side and uses 42us as the base. Assuming it follows standard Oneshot timing that means 42-84us pulses. With it, those who want can have 12khz looptimes

Thank you, that's some great info Smile
So with my KISS combo (kiss FC + 24 Race ESC), I should be using Oneshot42 instead of 125 to make the most of it and get better performance?

Yes that's right! if there is a better protocol I don't see why you shouldn't utilize it

Is it safe to use one f330 esc's? In my case I have ZTW spider escs , running BF 2.6 at 250 looptime on my sprf3 fc. Is it worth it to use os42? I just enable it in CLI?
