    Re: Goodbye

    Could I ask what books you bought. I bought a couple of books about C but they dont seem particularly suited to Microcontroller particularly with regard to libraries and hardware.

    Thanks

    Re: Math problem

    It means the mask is applied to the variable being masked and bacause it is an AND, only the bits that are a 1 in both number appear in the result eg assume the number 26 for d[0]

    Re: Math problem

    Just a guess that the & is a Logical AND and that the # is used as an indicator for binary so the the variable d[0] is being masked to get bits 0-2 in the first case and bit three in the second case....
