    Just convert Centigrade to Farenheit

    C/5*9+32=F

    although to maintain a bit more accuaracy with PBP integer maths I would do

    C*9/5+32=F

    then display the result followed by "F" instead of "C"

    Default Why the octal buffer?

    Hello chai98a,

    Why did you use the 74HC541 octal buffer?

    Is it because of a power issue between PIC and display?

    I had asked the same question before.
    AND I think the answer was that he had seen a design with 74HC541 somewhere. That was why.

    Hey gimo,

    I will accept 1 buck less then what Alain accepts.

    That is, of course, IF the OFFER is > 1 buck.
