You're out of luck, I wish I could help but, as far as I'm aware of, there's no magical tricks for that. Also I'm a pretty bad teacher... sorry

However, you just need to start with small chunks. Do some blinky, chaser stuff, read some push buttons, add the ADC and so forth.

Still, there's a heap of cool code example in here, copy/paste them, modify them and learn from it.

Datasheet may looks hard, but again, practice makes...better.

Should you need ANY help, don't hesitate to start a new thread. We're here to help!

Good luck!
