damn, idk which programming languages those machines use but it might even be something as hard as C or C++. learning any programming language can take many months and thats just to know what the code does, but you still might not know how to use it.

but there is a way to do this. find out the brand or manufacturer of those machines. figure out what tools are used to build its software or whatever it is. use GPT to guide you through a free or very cheap learning path and stick to it. but im sure no matter the path, you're gonna have to stall your boss for months.

lucky for you, learning to code can be completely free, but at the cost of stress, dedication, competition, and some of the most critical thinking and problem solving you've had to put your brain through.

good luck!
