Do you happen to know if there is a way to verify what is in a hex-file.
You open the .hex file (most any text editors will do, but you really want a hex...

Anybody here use LTSpice? Then you're probably looking at about a year before you get comfy with LTSpice, too. I've used it for ages (beats breadboarding hands down, although part availability and...

Adjusting LCD contrast by PWM It's possible that merely current-limiting the PWM made a difference too. Less current, less power, less noise. S.

Batteries in Series? Under certain circumstances balancing resistors are called for, but given coin cells (which a CR2032 is) they would just make life worse.
If you're building up to a hundred...

Setting/resetting reasonable device configs In theory it's possible for a used chip to have 0xDEADBEEF (or whatever) in the cookie field by sheer chance. Obdevel's item #3 sort of addresses that, but at a certain...
No. But you can tell where the bootloader starts. If the program does not start there, you do not have a bootloader. S.
There's a BOOTRST fuse. You might want to look at the documentation about where it puts the boot reset vector. S.
