Hello all!
I am new to the forum and don't have much programming knowledge in writing drivers for INDI. I want to use my Fuji XT-1 as my main camera, however, EKOS doesn't seem to be able to control the shutter speed.
During my preliminary testing, I noticed that when the driver is set to Camera Priority, an exposure taken with the cameras built in shutter is downloaded. This gave me the idea of using a small and inexpensive (Dirt cheap) microcontroller (in this case a Digispark Digistump attiny85) as a shutter release controller device.This way, many other cameras may be used with INDI/EKOS, not to mention other systems utilizing switches or relays.

Now comes my problem and question: How does an INDI CCD driver communicate with a separate shutter release on a given port? What command is sent and what protocol is utilized? If a driver needs to be written for such a project, where should I look for information? (The developer documentation was not helpful for me.)
