Flash RX with simple transmitter firmware

Post by Rob Thomson » Sat Feb 16, 2019 8:42 am

Hi Guys

I believe there was a topic on this a few years back but I cannot find it!

Essentially I am looking for a firmware option to convert a small frsky clone receiver into an frsky transmitter.

Essentially to make a wireless head-tracker.

Anyone have any ideas?
Slope Soaring, FPV, and pretty much anything 'high tech'
...........if you think it should be in the wiki.. ask me for wiki access, then go add it!

Looking at the prices of the miniature FrSky receivers why would you want to use a clone?

I mean a XM10+ costs about 10 to 15 Euro ?

Rob, I don't remember seeing that topic, and I was very involved in testing and building my own receivers from Midelic's project.
An alternative would be to build your own multimodule using only an arduino pro mini and a CC2500 RF module. This is what the frsky compatible receivers use.
You don't need much range, so any module without PA/LNA would do.
I have some very small receivers made with an ATtiny85 installed inside my radios for wireless trainer. They output SBUS.

I am not sure, but I think the receivers and the multi protocol module are not pin compatible, so, they can't share the code. I could be wrong of course.

Making a multi module with a single RF chip and an arduino is fairly easy, then you could use your receiver clone as a receiver..

Sorry I misread, thought you wanted to convert a clone into a receiver but you want to create a transmitter. No idea how to do that.

Yup.. issue here is the difficulty in fitting this into the fatshark goggles!

Annoyingly I actually had somebody send me a firmware to flash to a clone rx that would do this.. but it has 'vanished'
