This rule, while still true for embedded programming, is much more relaxed, especially with 8/16bit micros. | This rule, while still true for embedded programming, is much more relaxed, especially with 8/16bit micros. | ||

Doing this also increases the number of cycles needed to execute your functions as the variables needs to be loaded/unloaded every function call. On a low MHz micro with lots of small functions this can slow your code down. | Doing this also increases the number of cycles needed to execute your functions as the variables needs to be loaded/unloaded every function call.
