murat Posted May 22, 2006 Report Share Posted May 22, 2006 Hi, I have written the LabVıew code in the attachement for sending signals through parallel port. There is no problem with the signals, I can on-off the LEDs in the circuit repeatedly. But, I have problem with the frequency. Even if the loop is working at its highest frequency, I can not see a on-off switching of the LEDs more than approximately 0.5 Herz. Every shifting of the signal from one value to another becomes 2 seconds at a time. How can I increase the frequency of this operation??? Take care Murat Quote Link to comment

Take care Murat If you place a 1msec wait function inside the loop, does this change the frequency? Does it go faster or slower? Quote Link to comment
alnaimi Posted November 11, 2006 Report Share Posted November 11, 2006 accoring to that topic ,, how did u find the ports of ur card by LABVIEW??? BY using teh labview it self? Quote Link to comment
