FantomXR Posted April 17, 2014 Report Share Posted April 17, 2014 Hey, I'm wondering, if there is a chance, to add more LEDs to a led-meter. I'm asking because I can't find any 16-segment-led-meter and would need to build them by myself, which is a lot of work. I found a 20-segment-led-meter. Any informations about this? Thanks, Chris Quote Link to comment Share on other sites More sharing options...
Marxon Posted April 17, 2014 Report Share Posted April 17, 2014 (edited) Hi Chris, Why buying 20 segment bars? If you own a "multi tool" or a good saw it is less work then you think. To get my four 26 segmet bars I simply used two green 10 segmet led bars, then i cutted yellow 10 segment bars into 4 segment parts and red 10 segment bars into 2 segment parts. But i am sure any bar will work. Do you have a datasheet? Best regards Marxon Edited April 17, 2014 by Marxon Quote Link to comment Share on other sites More sharing options...
FantomXR Posted April 17, 2014 Author Report Share Posted April 17, 2014 For example this one: http://www.reichelt.de/Bargraf-LED-Anzeigen/GBG-2000/3/index.html?&ACTION=3&LA=2&ARTICLE=31506&GROUPID=3016&artnr=GBG+2000 I don't want to cut other bargraphs... I want it to look nice and I'm afraid, that this is not a perfect solution. Besides this, if I can get 24 LEDs running I have a higher resolution...

Marxon Posted April 18, 2014 Report Share Posted April 18, 2014 (edited) Non 10/20 segment bars seem to be rare. I only found red 8 segment bars on ebay..http://www.ebay.com/itm/5pcs-10x20mm-16-Pin-DIP-8-Segment-Red-LED-Bar-Digital-Tube-Replacements-/231132246488?pt=LH_DefaultDomain_0&hash=item35d08e31d8 But they have common annode.

FantomXR Posted April 18, 2014 Author Report Share Posted April 18, 2014 Thanks for the link. Yes, I could chain two of these. That should work. Another idea is, to simply add two SR and add eight LEDs, which are assigned to a separate led-pattern. Than I scale the cc-value on the first led-stripe from 0-80 (value need to by correctly calculated) and the second stripe from 81-127. How about this?

FantomXR Posted April 20, 2014 Author Report Share Posted April 20, 2014 Sorry, that wasn't clear. What I meant was, to chain two led-matrix-pattern. To simplify the case: Is it possible, to set up 2x16 LEDs (=32 LEDs in total) and to program the ngc-file in the way, that the first 16 leds listen to cc (x) and value 0-63, and the second set of leds to cc (x) and value 64-127? With that setup it should be possible, to get a higher resolution on led-feedback or am I wrong? Quote Link to comment Share on other sites More sharing options...
Marxon Posted April 20, 2014 Report Share Posted April 20, 2014 (edited) Ok thats what i thought first, too. Yes of course, you can do it this way. Best regards Marxon Edited April 20, 2014 by Marxon Quote Link to comment Share on other sites More sharing options...
