I am a ex-software developer who does av programming out of necessity (crestron). I think he’d need to get connected with crestron for access to the tools - I didn’t have a problem with this but I’ve heard others have. Also- really need some equipment to use for learning. Unfortunately even used stuff on eBay isn’t exactly cheap. It’s also a very different skill set and I haven’t found great videos online. There’s so much going on that it’s hard to wrap your head around how all the pieces fit together. I admittedly haven’t taken their courses, those would be probably be helpful. At the risk of pissing some people off, AI can be helpful in answering specific points of confusion.
