MAX7219--any schematic or circuit diagrams?

Recommended Posts

Guest

Since I ordered MAX7219 ICs few months ago, I have already went through few expirments. And to say this, some of them are pretty complicated since I never have any circuit diagrams. The only effort I have done is going through pin diagram of this chip and so far some of the expeirment I did was a sucessful solution, some of them weren't. Apparently I could done some miswiring or did not comprehend the function of each pins. So I am wondering whoever done with MAX7219 experiments, would you care to share out the circuit diagram or known any websites that has all of information according to MAx7219's connections with 7 Segment digit displays and LED. So that way I could get idea how I did on connection, and can be used for future purpose. Let me know.

Hi, I don't know about the Max7219 IC, but I am working on an FSBUS system that utilises the Max 232 IC. I don't know how similar they are but you can check out the FSBUS circuits atwww.fsbus.de

Have you already done a search on Google? A couple of weeks ago I found this page, which also has more links at the bottom:http://ee.cleversoul.com/max7219.htmlApparently the "Basic Stamp" users like the 7219 a lot. Search for that, too. For many users, the Stamp and its clones might be an easy way to get into programming FS gear. These are tiny all-in-one computers with I/O. See:http://www.basicx.com/http://www.parallax.com/http://www.oopic.com/http://www.technologicalarts.com/etcBest,Kev

Gentlemen,You may go to AVSIM library and look for fsdigit.zip , also go to 23 Dec 2002 message in this forum and you will discover a lot of information on this subject.best regardsAlberto Kunzel

Have you tried the manufacturers webpage ?www.maxim-ic.comThey have the datasheet, schematics plus some 10 application notes and much more on the web.Plus, you can order upto 2 *free* samples of *any* of their IC on that webpage too.Might want to check that out.Michael
