#154736 - Do you understand why? Responding to: ???'s previous message |
You end up with 2 issues.
The first is globals that are read and written between interrupts and main(). This is true for all embedded systems The second is that Keil for the 8052 does not push all on to "the stack" it requires you to tell it if a function is re-entrant. This is due to hardware limitation of the 8052. Not that using re-entrant function has a cost in RAM and ROM. Other 8 bit micro controllers / Compilers may or may not have this limitation. |
