Title: How many frequency should be output to ESC ?
Post by: yasushi on November 25, 2018, 12:52:12 pm
I want to controll brushless motor through ESC.
I have used Arduino Uno. I output pulses with PWM.

How many frequency should be output to following ESC ?

and How can I check the frequency to be output to the ESC?

thanks.

Hi,

The documentation you linked says :
Super high refresh rate, no buffering of the input signal, resulting in more than 490Hz response rate.
Like a usual Simonk Esc.

Using a oscilloscope, and monitor 490Hz PWM signal (https://librepilot.atlassian.net/wiki/spaces/LPDOC/pages/31588402/PWM+PWMSync+Oneshot+Output#PWM,PWMSync,OneshotOutput-PWM-490Hz)
Refresh rate can vary (300Hz to 490Hz), motor RPM is based on pulse length.
