ccie Posted April 14, 2009 Report Share Posted April 14, 2009 Hi all , i have successfully displayed a full wave rectifier on labview waveform graph via a serial port thRough a microcotroller , but when i turn off supply to the rectifier i expect the rectifer output to be removed from the labview waveform graph but it still gets displayed , why is it so ? and is there any way to make the waveform change in real time. find the attached VI Quote Link to comment

Thanks confidence and downloaders, So labview does display what ever bytes it receives in real time ? [yes|no] , the reason for asking this is cos i need to know where the problem lies(either in ucontroller program or labview) I am really new to labview , pls can anyone modify my code to display nothing if no bytes exist at the serial port and upload. Thanks Love Zinedine. Quote Link to comment
