MP Posted May 13, 2006 Report Share Posted May 13, 2006 shahzad,This is a very hard question since it depends upon what is being converted to a display. Some examples: Direct connection from parallel port is possible. No ICs. A digital signal from a micro controller can be used without any ICs, whereas an analog signal will need a little help. A voltmeter IC such as 7107 can connect directly to a LED Display. We have a project in our "Projects" section based on this. See the link at the top of the page for "Projects".A circuit used with digital gates normally needs 2 ICs such as 14553 and 14543 to convert the pulses to the correct format........oops, the secret is out ;DMP Quote Link to comment Share on other sites More sharing options...
gogo2520 Posted May 14, 2006 Report Share Posted May 14, 2006 hello shahzad-h the secret ic is the 4511 cmos shhhhhhhhh don't tell anyone I told you gogo Quote Link to comment Share on other sites More sharing options...
MP Posted May 15, 2006 Report Share Posted May 15, 2006 Thanks gogo, I forgot to mention the BCD to 7 segment display ICs.Shahzad: Here is a little diagram to get you going with the 4511 that gogo has mentioned.MP Quote Link to comment Share on other sites More sharing options...
gogo2520 Posted May 15, 2006 Report Share Posted May 15, 2006 Hello That looks good MP, that should help shahzad-h get started with 7 seg's. as far as 5 by 7 dot matrix displays a 74hc595 and a microcontroller would work I have been playing around with scrolling message signs using a pic. have fun gogo Quote Link to comment Share on other sites More sharing options...
