    Talking The Missing resistor ...

    Hi, sayzer

    As you're asking, it's a pleasure ...

    Just insert a resistor between your Emitter and ground, and the transistor collector current will simply follow linearly ( w. a little offset due to Vbe ...) the PWM value ...
    An U/I converter w/ OpAmp could wipe off this offset, if needed ...

    No, no, don't send flowers ....

    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 " !!!
