  4. Converting ASCII HEX digits to decimal...

    My project recieves an ASCII text string such as "3FE35853" and stores them in an array. I need to convert each ASCII byte in the array to its decimal equivalent.

    example:
    "3" = 3
    "F" = 15

    I actually started down the IR path several months ago, by buying another IR control to modify.

    My MAX3421 Eval kit arrives today, so I will be able to experiment with USB control. Who knows, I...

    Unfortunately, the Nikon D40 only has a USB interface, so USB commands are the only option.

    I ordered the MAX3421EVKIT-1+ from Digikey to help me understand USB a bit more and to develope my camera intervalometer project.
    There are many questions about enumeration and other things. Just...

    Hi Martin,

    Thanks for the DIG tip. That eliminates all that math.

    Yes, I know I can get the .5 resolution, but I don't need it for this simple project. But, that doesn't mean I won't...

    Hi Mike,

    It doesn't take too high of a step to "go over my head". Anyway, I am using the 16F648A and I am not sure about DDS and PWM, but I did see that some people generate sine waves with PICs....

    Yes, pretty cool product.

    I wanted to use something not out of a box. Homebrewing it also make it flexible.
    I think with those products you're pretty much stuck with only modifying a couple of...
