    PbP " only " 470 Words ... always is the winner.
    Bravo Alain!!!

    après quelques tortillages de cerveau ...

    on se rend compte que " angle " passe de 26 tribord à 26 babord pour la tension d'entrée qui passe de 3.02v à 5.02v , ce, de façon linéaire ...

    si l'on y regarde de plus près ... et ,compte tenu de l'affichage en degrés, sans décimales ...

    ça nous fait tout simplement ...

    26 degrés de variation pour 200 points de variation du résultat de conversion ...

    d'où ... la fabuleuse équation devient tout simplement :

    angle = 13 * ABS ( result-823 ) / 100 ...

    Qui a éclaté de rire ???
    Hi Alain,

    Was it too late for the original student to use this new formula considering the time constraints you mentioned?

    Halas yes, Mike ... He PMed me he had no time to change his report and explain how to simplify the formula, once having seen the practical result, so he had to use the whole original formula for programming ...

    despite I sent him the reduced program.

    no " magics " allowed in such reports ...

    he's just authorized to mention the soft can be modified and reduced , while presenting his work at the blackboard ... and next year students will make the mod ...

    But ... being honest ... you've cheated a bit !!!

    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!

    How so? If you mean that I took advantage of all your hard work and careful analysis when I simplified the formula then you are correct (LOL).

    Your summary made it easy to recognize the ralationship of 52° spread across 100 (8-bit) or 400 (10-bit) ADC counts. You really should have spotted this yourself when you wrote it (LOL).

    Anyway, I'm sorry the student could not take advantage of the simplified formula.
