send long values to a drone with a transmitter?

Post by look001 » Mon Mar 28, 2016 11:46 am

Hey there,

my goal is to send long values like pixel values to my drone. I came to the idea to use an arduino that sends ppm signals to my transmitter (turnigy9x). The problem is that a channel is not big enough to send large values like 1080. I gues it's only from -100 to 100. Also i need to send two values because a pixel has also two. So what can i do?

Hopefully my question is clearr

Thank you!

Nothing in the control link is meant to send an exact numeric value so that's not suitable without some custom encoding scheme.

Wasn't there a project on here at some point that allowed you to send data to the plane via a channel.

Some sort of pulsing control to multiplex multiple 'extra' channels in one high channel?

Yes, I remember that too. AFAIK they could send 4-5 bits of data at a time with replicated cycles as there's no real means of synchronization.

If using FrSky 'X' gear, so SPort telemetry, what about a couple of the UART sensors, then you get a serial communication stream.
