 		 #169846 - SDCC interrupts visible to main
Responding to: ???'s previous message
Andy Neil said:
If the breakpoint is correctly set, but it isn't hit, then either the emulator is faulty, or the code is never reaching that point!

Is your interrupt service routine in a separate source file? If so, have you added a prototype for it visible to main? SDCC requires this to create the interrupt vector. Juergen Christoph already pointed this issue out to you. ( http://www.8052.com/forum/read/169814 )

You could also try to set the breakpoint at the interrupt vector and see if it gets hit. If it does, you know the interrupt is enabled and happening.

which hardware Emulator can work with SDCC            01/01/70 00:00      
   but it can't work            01/01/70 00:00      
   OMF support?            01/01/70 00:00

               It's time you read the SDCC documentation!            01/01/70 00:00      
               You Mean Break Point?            01/01/70 00:00      
                  Yes ,I want to single step            01/01/70 00:00      
                     cannot set?            01/01/70 00:00      
                        I can set the breakpoint but it isn't hit?            01/01/70 00:00      
                           Confusing!            01/01/70 00:00      
                              SDCC interrupts visible to main            01/01/70 00:00      
                                 Gee ... does SDCC allow only one breakpoint?            01/01/70 00:00      
                                    The compiler            01/01/70 00:00

                     I can not set a break point and can not single step            01/01/70 00:00      
            I use the ICE to debug my program            01/01/70 00:00      
               Probably too late to ask ...            01/01/70 00:00

            Can you tell me your Development Environment            01/01/70 00:00      
               I program in ASM and use a debug monitor ... no ICE!            01/01/70 00:00      
   ask at Micetek?            01/01/70 00:00      
   Maybe that SDCC interrupt "feature"?            01/01/70 00:00
