Anyway I'm not gonna ramble about my stuff, lets stay on topic.

it's "it's all laid out" not "it's all layout" ;D.
I am designing the PCB right now.
All the components are laid out.I have to now rout 300+ connections :phew:(most of em are GND and VCC and I already connected about 75)

Yeah, but the code is already complicated enough for me.With 3 devices on I²C and 1 on SPI :phew:.
I am trying to do most of the things in the hardware side as possible.

I see, I'm more experienced with software dev than electronics so that just seemed obvious to me.

You could do a simple RC thing with a large time constant, but that's gonna affect it all the time not only during start up. I think I'm to much of a noob to come with any meaningful advise when it comes to doing it in hardware ;D

BTW out of curiosity what micro are you using?
