I used to think 'Bad Bill' was someone out of a story book, till I tried to parallel address a a/d convertor using the pc parallel port , best clock rate from a 550MHz P was 50 Khz , and then the whole thing locked up while it 'spoke' totally useless , had to abandon the project ..and that was with the latest C++ big bucks compiler, that made bigger and bigger exe files as time went on
I have a DDS kit from the now defunked Hands Electronics. It is programmed via the printer parallel port and the instructions recommend using the supplied program by G4OPE using DOS. (I have a vintage laptop specially for the job). I am now not able to read the DDS PIC16C84 memory anymore although I can program it by first setting all the memory to zero and overwriting with new frequency data. I am unable to tell if the reading problem is with hardware or software. Does anyone have any knowledge of this Hands DDS unit? I would be most interested to find a way to apply data modulation to it.
