 		 #169323 - Divide your problem into parts
Responding to: ???'s previous message
Dear Jr,

Try to divide your problem into parts. What made you think that firmware is the only problem?

Have you checked following?

1. Is sensor output changes w.r.to temp (e.g. when you put your finger)
2. If so is output of ADC changes accordingly?
3. Are you reading ADC correctly? Have you checked timing of start, end etc... controls of ADC.
4. If all above is working properly then considor the part of firmware you posted.

Regards,
Mahesh

      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
