Hi Stefan,


So the question is if i can use the WOLF gui program to get what i want? Some things can be changed in the config file but don't know how i can get the RS232 to generate the toggle signal for the phase shift :-/


Simple: You cannot drive the RS-232 with the WOLF user interface. Producing a precisely timed digital signal which isn't (by coincidence) a multiple of the serial port's baudrate is almost impossible with windoze. Reason: Windows uses buffering between the application and the ports hardware. Sending a byte to the serial port API doesn't mean it is placed in the UART's transmit shift register. It may get there in a microsecond, or in a millisecond, or even dozens of milliseconds later. Thus the RS-232 port can only be used for RX/TX switching, but not for the digital modulation itself (at least not without an extra hardware; PIC etc etc).

Cheers,
  Wolf .
