in my code im having different times to my coffee machine for every push button but i want to manipulate those timers some how like entering service mode in original circuit by pressing the stop button for few seconds then change every time and save it then it works as the last change has been made. thx forward

 

Whooh! Never seen so many if else statements... You need to look up "state machine" There are better ways to do this..

can u give me an example

I looked through your code and found it almost impossible to follow..

 

i tried to understand what is state machine but i couldn't ,but anyways thx for trying

 

Just look on pic sites for automated machines to see how others have done this...

 

ok i ll thx for ur concern

Here’s a link to a forum discussing coding a state machine in C. It discusses one way, but that’s may be others.

Good link but I would advise beginners to say away from polymorphism in C (function pointers) in interrupt I/O driven, time critical state machines on controllers. The stack space is limited (for passing state variables), context switch times can be unpredictable and it's easy to have atomic update issues unless care is taken. The computed goto switch construct can be clumsy at times but it provides a good model of actual processor execution flow.
