 		 #129057 - code tested at simulator
Responding to: ???'s previous message
Andy Neil said:
You don't think it looks like a "Stuck-At" address problem, then?

As ever, of course, this could easily be tested by simply running the code in a simulator:
If the simulator produces the same results, then the error does lie in the code;
If the simulator does not produce the same results, then the problem most likely lies in the Hardware.



Hello sir

I have tested my code in simulator, it gives the right output in the simulator ,and i think so the simulator works as it takes that all connections should be in right way and also the program should be correct.. And my program is correct,it gives right output in simulator but when the same program runs on the hardware than it will not give the appropriate output which i suppose to be want...
So i don't know about that the hardware connections is wrong or some-else problem...

   I think Neil is asking            01/01/70 00:00      
   Isn't this a 'C' problem rather than a RAM problem            01/01/70 00:00      
      Really?            01/01/70 00:00

                  answer to "why":            01/01/70 00:00      
                     but dont forget to put pull ups its port 0!            01/01/70 00:00      
                        for the test - yes, sure, sorry, I forgot            01/01/70 00:00      
                  "Hardware tested" and who gives a hoot            01/01/70 00:00      
                  Tested?!            01/01/70 00:00      
            it's the HW then            01/01/70 00:00      
         Yes, it looks like that.            01/01/70 00:00      
            Oh no it doesn't!            01/01/70 00:00      
               first of all, let me be clear ...            01/01/70 00:00      
                  not just stuck-at            01/01/70 00:00      
                     Good point!            01/01/70 00:00      
                        Let's give him credit ...            01/01/70 00:00
