Title: Re: Can anyone solve this circuit Post by: zuisti on April 17, 2007, 03:25:58 15:25 If the LE and DS pins (5 and 6 on IC 74c926) are in logical 1 (for ex. with an ls04),
the circuit is working (it runs, displays something, not only 0000). I don't know why but it's not perfect yet... (maybe wrong modell...) zuisti P.S. I think the frequency of the internal multiplexing and the main clock are in conflict. Change the value of the C2 to 100nF and see...

As I wrote (here: http://www.sonsivri.com/forum/index.php?topic=681.0), "Please to consider the multiplexed displaying works in the "human eyes" only, beacuse it displays one digit at a time. Press "pause" at times in the Proteus simulation..." The Proteus simulation speed isn't great enough for the real-time multiplex displaying I uploaded the working but a bit simplified DSN file: http://rapidshare.com/files/26506758/74C926_IC__1.DSN.html Hope this helps. zuisti Title: Re: Can anyone solve this circuit Post by: sureshsharma2032 on April 17, 2007, 06:33:14 18:33 why are displays not working well
