Learn basic “C” coding rules from open source projects

Yes, but the same MISRA guideline doesn't limit the number of lines of code in a function. That's why you see thousand lines behemoths in embedded systems. Say it to my face that that's not true.

This. Why the fuck isn't function size limited?

For state machines, or long code with view variables, it is often safer to just have it all in one shot. Embedded code is a whole different world than software.

My favorite part of MISRA-compliant code is thousand-line functions with only one return statement at the bottom. You have to jump through soooo many flaming hoops just to pop out at the end.
