How to control E90 via its UART by another app

[h-elsner]

During my work on a E90 camera I didn't only fount out how to calibrate it but also how to control the gimbal (tilt, pan, tilt mode, pan mode) by another application via camera's UART.
This may work on all cameras that fit H Plus (C23), H3 or H520.
Gimbal control is done with a Yuneec specific MAV message, MsgID 5000.
This opens the possibility to reuse those cameras to other purposes.

The project is here: GitHub - h-elsner/E90controlDemo: Control a C23/E90 camera to use for other purposes

Hi,
Looks very interesting !
I've been looking on your website for more information and on GitHub but I can't figure out how to test it.
Can you provide me informations ?

If you want to use those cameras on other devices or standalone, you need to access to the serial connection (UART) of the camera somehow.
This is the same with the calibration tools. In the manuals for those tools is more information how to connect the UART of the camera (page 2):

Four contacts of the six on the camera mount are used. Power is 12V - 16V, Rx and Tx are 3.3V signals.
