Gentlemen,Someone of you tried to do a 7 segments display for autopilot panel without using Epic ?I am trying to do that but ...RgdsAlberto Kunzel

Hi AlbertoI am using 7-segs without EPIC. Its easy and vey cheap (chips are about $5 and the 7-segs between $1 and $4 depending on what you get.)Use a MAX7219, connected to the parallel port. Then its just a matter of toggling the pins high/low as needed. This way, each pin can drive 8 chips, each driving 8 7-segs (64 leds in other words).Do a search on google for MAX7219 and download the datasheet for the chip. The circuits are very simple and easy to build, and they work great. I'm so pleased with the way its turned out that I'm driving ALL leds and segs from these chips. I figure I'll need meybe 6 for the whole cockpit.Dave

Hi Dave,Thanks for your information, I will go into google to discoverer the MAX7219.I understand that you did a specific soft to send the information to the parallel port,so, what soft did you use ?Please give me a little more information on this matter.Thank you very much.Alberto Kunzel

Hi Alberto,Take a look at this site: http://www.project737.net/It may have what you're looking for.Richard

Hi AlbertoI wrote the code in VB, its very simple, using the parallel port driver from TvICHSoft (Link below)Davehttp://www.entechtaiwan.com/tviclpt.htm

Hi Dave,I reached the site you indicated me, I suppose that you were speaking about TVicHW32( or 50 )soft.Also, I got the datasheet for MAX7219, so, I have a lot to read this weekend, I want to see how is easy is that for me, if you would like to talk with me out this forum my email is : [email protected] [email protected] again.RgdsAlberto Kunzel
