Hello !
I've been trying to understand the functionning of the PPM and PWM signals for some days in order to write an algorithm that can generate them via a an arduino . However , I can't find suitable informations about the communication protocol used by RC transmitters .
How is the receiver able to differentiate between the channels when it receive a PPM signal ?
How am I supposed to send a PPM signal that maintains the motors running if it's a serie of 20ms pulses ?
Sorry if those looks like dumb questions but I'm trying to understand RC control as much as I can and those issues are really slowing me .
Also , if you have any useful links explaining with accuracy PPM signals (for multicopters use only) , I would gladly read it . (It can be in english , french or spanish , I don't mind)
Thanks in advance!
