DrBunsen Posted September 3, 2003 Report Share Posted September 3, 2003 Hi,I've spotted an auction for some nice-looking Vacuum Fluorescent Displays on Ebay, but the seller's information says he will strictly only sell to buyers in the USA.They are 2x20 VFDs, information here http://www.noritake-elec.com/tversion.htm. He is selling them in pairs for a pretty reasonable price. EDIT: I note the following thread has some information on compatibility. http://www.midibox.org/cgi-bin/yabb/YaBB.cgi?board=parts_q;action=display;num=1061702584;start=6#6. Please don't buy anything for me until I've checked this out. /EDITIf anyone in the States would like to bid on a pair for me (and snap up the rest while you're at it if you like ;D ), I could airmail you a US dollar money order for the cost and shipping, or Paypal if I get it sorted out soon...I have written to the seller asking for compatibility information and if I can bid, but I have had no reply. I'll take that as a "No"...The auction listings are here: NB the first two finish today, and the last one in two days time.http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&category=4660&item=2554732235http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&category=162&item=2749987447http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&category=4660&item=2554732235EDIT: I found some more, different sizes, some graphic, some in Europe, some ship internationally:http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=2554708298&category=26206 http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=3044426883&category=12070 http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=2555227621&category=26206 http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=2555033053&category=36811 http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=3428835303&category=32897http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=2555556193&category=26206 Quote Link to comment Share on other sites More sharing options...
goyousalukis Posted September 3, 2003 Report Share Posted September 3, 2003 I can do it for you if you want. That way you can just send me the total amount. Let me know....Justin Quote Link to comment Share on other sites More sharing options...
DrBunsen Posted September 3, 2003 Author Report Share Posted September 3, 2003 It appears the first group I listed are the Noritake T-Series. The thread I linked above suggests that the U-Series are the Hitachi compatible ones. So unless I hear otherwise I will skip these and wait for some compatible ones to come up.Thanks anyway goyousalukis. Quote Link to comment Share on other sites More sharing options...
Guest Da5id Posted September 4, 2003 Report Share Posted September 4, 2003 Precisely right. Nortake U series is HD44780 compatible (with a few minor differences, I assume you've checked out the datasheet) and apparently the "W" models are a subset of this line as well.The "T" series are totally different, however...EDIT:Here's a note on the differences between the "U" version and standard HD44780: "The VFD instructions are very similar to a standard parallel data LCD except for the data line addresses, which have different values."And brightness is controlled via software, don't have any idea what impact this has on the MIOS LCD code...

ultra Posted March 18, 2009 Report Share Posted March 18, 2009 so has anybody figured out how to make the t-series compatible?when connected, they give garbage on the screen. they're clearly various kinds of characters, but nothing close to what i want.ultra Quote Link to comment Share on other sites More sharing options...

lylehaze Posted March 18, 2009 Report Share Posted March 18, 2009 So like a schmuck, I checked the above links, they are no longer valid, probably because they are dated from five years ago..What I CAN tell you is that I use Noritake/Itron 2X20 VFD displays in all my projects.The specific part I use is CU20025ECPB-U1J. I have a PDF data sheet available if anyone wants it.They are definitely MIOS compatible, and you can see one in the pics I have posted for the MBMixer project.Some differences from "standard" LCDs:These use a bit more power than an LCD, so check your regulator heatsink.These do not use the brightness or contrast controls from the core, but as noted above you can control brightness from the code. I think there are 16 levels available.I have also written 4 bit code for other projects. I have not tested the 4 bit MIOS code, but I doubt there would be any problem.The displays I have include the vertical bars needed for the bargraph display mode of MBMixer level settings. I don't know how common those are, but the docs describe what and where these special characters are.I hope this helps someone..??LyleHaze Quote Link to comment Share on other sites More sharing options...
ultra Posted March 18, 2009 Report Share Posted March 18, 2009 well it appears that your u-series and these t-series are a different story. but the other info is helpful :). Quote Link to comment Share on other sites More sharing options...
