    Convet Characters into HEX

    Hello,

    I currently have a character array of 16 chars. These 16 chars are actually HEX pairs meaning hexstring[0] = 3 hexstring[1] = f, hexstring[2]=3 hexstring[3]=d, ectc. What I need to do is join these HEX pairs togather and create an array of 8 chars.

    I need to be able to take hexstring[0] and hexstring[1] and turn them into the HEX(3f from above) and make 3f = to newString[0].

    Thanks for your help,

    techyjt

    Run a loop 8 times, each time picking up 2 chars and use strtol() to convert it to an integer. In a new variable declared as 8 bytes, store this converted number at a specific location ranging from 0 to 7 being incremented each time the above loop increments.

    You'll find something similar if you look hard enough.....
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    OK, but you did look at this one. It doesn't answer your question directly, but it gives you some clues.
