    Default Something strange, and its doing no good...

    So the 18F2550 chip i am currently using for some ADC work is doing something rather peculiar... I have it set on 10 Bit ADC and as far as i under stand this means i should get a response of 0-1023. How ever i am getting a response of 0-64320 ish with 5V. working in 8 Bit mode i get 0-255.

    My setup code is:

    Code:
    
    DEFINE ADC_BITS 10	
    DEFINE ADC_CLOCK 3	
    DEFINE ADC_SAMPLEUS 50
    Anyone else confused?

    The great classic question ...

    Did you think to use RIGHT justification for the result ???

    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 " !!!
