> Isn't that about the same rate as you'd get by random guessing? ;) Yes, I could achieve the same result if I reverse-biased the diode and derived the answer from get generated noise. But obviously I don't know how to do that because I don't know the cathode from the anode, so that option is not open to me. But in the meantime I got the Olimex arm-usb-ocd working within my application building tool! Next I must find out why this works with some Olimex boards but not with the -MT (character LCD) boards. -- Wouter van Ooijen -- ------------------------------------------- Van Ooijen Technische Informatica: www.voti.nl consultancy, development, PICmicro products docent Hogeschool van Utrecht: www.voti.nl/hvu -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
