I·want to measure the high time pulse in a RC signal. In a simple way? Help!!
Sincerely

Hi Oland,

Could we have some background information please?

A little about the hardware and its current software; and some data for the pulse too ...

Regards,

Hi!
Tony thanks for asking!
Jim, I think you ,ve got it.
Some background. Don´t fell asleep!!
I intend to make a better control for an model engine. more safe!
I don´t know if you guys what it is like.
When you are flying quite a distance away it is hard to hear if when
the motor idle it will stop for a reason or another.
I want to control the idle and therefore I will measure the rpm (2500)
and let the propeller adjust the throttle servo to make it safe.
The propeller must know when I mean idle thats why I want to measure the
pulsewith . The servo will adjust itself to hold the rpm between say 2500 to 2600 .
Idle is about 1 ms full speed is 2 ms.
I am a novice in propeller though I have done som code whith stamp.
I think I must do this in small portions so I just finished the rpm measure. WOW.!!
This is really fun but I think I have to study a lot more.
I understand this is the very fun one whith propeller but what I struggle.

Still awake?

Thanks both of You for your attention.
