Hey Folks,
I'm in the process of gathering hardware to build a stack rail, based loosely on this project (https://pulsar124.fandom.com/wiki/Pulsar124_Wikia)
My target cameras are Canon 550D and 600D
I am interested in finding out what (sensible) approaches I might consider to triggering the camera (and flash) - is this something Magic Lantern can help with - via an API or python/arduino library?
IIUC the current favoured response is to fake the cable trigger/electronic trigger (very hardware, much hack), but it'd be extra nice to be able to adjust camera settings and get feedback from the camera.

"Faking" the cable trigger is really easy, which is probably why that's recommended. It's a standard connector and you just need to bridge two wires, so you can attach it direct to GPIO. I wouldn't expect you'd want to change camera settings per shot for a stacker?
If you can be more specific about what you hope ML might help with, we can give a better answer. You certainly can use ML to take a picture. You can control many cams, including Canon cams, via PTP, for which there are libraries available.

One of those PTP options: gphoto2. Maybe a RP-compatible device offers more flexibility
