IntroductionHere are some tips and tricks to manage your application size.RAM and ROM usageThe total RAM usage is: ZI-data + RW-dataThe total flash usage is:Code + RO-data + RW-data ZI-data - Zero initialized data, data variables set to 0 RW-data - Data variables that are different from 0 RO-data - Constants placed in flash This means that if you have a variable defined globally with the const flag it will most likely end up in flash, while a variable that is prone to change will end up either in RW...
