Send pulse of 0.5 millisecond every 10 milliseconds
-
I need to send a pulse of half a millisecond every 10 milliseconds with a Onion 2+. I have tried through a gpio in python, but the fastest pulse I could send was of 3 ms, and every 20 ms.
I wonder if anyone has done it, or has an idea of how achieving this. Any help is highly appreciated.

I need to read a digital input and when detecting a pulse (from false to true), then wait for a variable time between 0 and 10 ms, and make the pulse of half a ms through the output.

Please check the
onionscript on FW v0.2.0 b195 and above.As you know pwm0 (GPIO18) is available on all EXPANSION HEADER (except on Power Dock 1).
Omega2+ FW v0.2.0 196
omega2-ctrl gpiomux set pwm0 pwm
onion pwm 0 5 100Frequency 100 Hz, pulse lenght 0.5 ms, (positive pulse train) - this is what you requested above - I think.

You have a problem that is increasing...
then wait for a variable time between 0 and 10 ms, ...
What is the resolution of this delay? nano-, micro-, milisec?
and make the pulse of half a ms through the output.
Do you want to send a single pulse (single shot) or a pulse train than before?
Are there any other requirements?

The problem is i need to first detect a pulse in a digital input, then send a single pulse of 0,5 milliseconds. The delay between both events is between 2 and 8 milliseconds.
