I have successfully got 3 analogue cameras working via FPV video switcher. I had to place RC filters on each line to clean the image up but now the images are nice and sharp.
Im having an annoying time with the switching of the channels. The switcher can use PPM and PWM from a RC Receiver.
Basically if you took the full range of a servo and split into 3 sectors, as the “position” of the servo goes through each sector it selects the camera in that sector, if that makes sense. Designed for use with a 3 position toggle switch on an RC remote.
Using a PWM channel out to switch is creating problems, im guessing due to servo frequency being way to high. It is switching the cameras but getting major glitching on the image. (Anyone have any other suggestions?) I’m having success using a relay channel however i have to time my on/off presses to create the “illusion” of a PWM signal and its frustrating and spiratic.
My ideal scenario is to just toggle a relay channel and have each camera switch in sequence. Can this be done via a Mavlink script possibly?
Or any other suggestions on parameters that can be changed to help this scenario out?
Im Fully open to ideas on how to tweak this please.
