I have just sold an invention to a medical company. It's really simple, just based on a blinking LED, a beeping piezo, sleepmode and watchdog timekeeping. Problem is, they loved it and ordered 10.000 units right away.
And I'm in over my depth. I know nothing of large-scale production, but I'm learning. I now need to choose the optimal microcontroller, based on price mainly, and help writing a small enough program to fit on it. It should be easy enough for anyone who knows programming for real.
This could mean programming a PICs or an ATtiny. Naturally, I'm fully prepared to pay for help. With one condition: that the help is also a teaching process and I get to ask a lot of newbie questions :). I really want to learn this, but there are steps that's very hard to climb without guidance and explanations.
