Okay...likely stupid question but I don't know where else to ask. I have a friend who is doing the electronics for me for the chest display. I thought I was so smart by having the "blueprints" all printed off for him (the ones that were so kindly posted by Shackman I believe). But....he just called and asked if I realized that it's supposed to have some sort of programming. He said that's no big deal because he can do it, but he needs some sort of code. Code, I say?? Good grief.
Now...perhaps he's mistaken or worse, doesn't know what he's talking about. And...perhaps since I've read lots here and have seen that these are being sold it's a question I really shouldn't be asking. BUT.....there's only one way to find out and that's to just ask. So if I'm stepping on any toes, I sincerely apologize. But if someone is able to give me the answer, I would greatly appreciate the assistance!
