 		 #169331 - Debugging techniques
Responding to: ???'s previous message

Print out the program and go through step by step on the paper with a pencil

It is an excellent suggestion and, as he said, would very quickly answer your question!

A somewhat less laborious approach would be to run the code in a Simulator - there you could single-step it and watch exactly what happens.

If you had a chip with on-chip debug, you could use that to single-step in the real hardware and watch exactly what happens.

These are basic and very powerful debugging techniques - make the most of them!

   Excellent question            01/01/70 00:00      
      agreed, but one thing missing            01/01/70 00:00      
         8 data lines for 7-seg            01/01/70 00:00      
            I see no con2 connections on your schematic and ...            01/01/70 00:00      
               also            01/01/70 00:00      
               CON2 is good.            01/01/70 00:00      
         7 segments, plus DP            01/01/70 00:00      
            the 8 data lines are each segment + dot            01/01/70 00:00      
      Thank you            01/01/70 00:00      
   Look at your code            01/01/70 00:00      
      You're right            01/01/70 00:00      
         First try to solve the simplest things like DELAY            01/01/70 00:00
