Address sent. I will try my best getting it running in serial mode - hopefully I won't turn that green pertinax to something like carbondioxide and other ugly, black things 
Eheh...  Sounds good.... The USB thing sounds interesting, too....
Noritake - the "U" series seems to be straightforward - parallel only, 14-pin connector, +5v power and HD44780 compatible... My findings show that all the "U" series models hookup the same way and run easily with many different LCD software in HD44780 mode....
The "T" series (like the subject of this thread), on the otherhand, is parallel and serial (seems with limitations), 16-pin connector with alternate serial 3-pin connector and +5v power..... Hmmm, seems to be a very tough nut to crack......
Here's some techdocs on the Noritake CU20045SCPB-T23A (if you don't have them already):
Short version
Long version T28 model (sister display)
Identical Samsung model (long version)
I am waiting on some VFD filters (red, blue, green, yellow, etc.) to arrive... Well, actually they are photographer's gel sheet. They won't be here till Monday (10th). I will throw some of those in the box and the package will leave on Tuesday (11th).
So, Good Luck and let me know or post back here when the package arrives....
thx man, CD

Surely not. The problem is - I don't have one  Shark5060 connected the VFD, I just got it completely running.
Jeez, Olaf, I hadn't heard from you in a while so I thought you were ignoring me...   Eheh....
Well... Noritake made it as simple as the IEE's - set jumpers, connect three wires and off with it. The problem is, the Noritake only accepts TTL-Levels (0V and +5V), not RS232-Levels (-12V and +12V). Looks like the IEE's were ready for RS232.
Here's a pic of the back of the BG Micro (IEE) 2 x 20 VFD:
Perhaps it has its own way to get RS232 levels onboard?
Obligatory front shot:
BTW, www.bgmicro.com got some more of these in but they bumped the price to $32.50. (They were originally $20). Still not a bad deal for a huge display with big 9mm characters.... I know some Europeans that bought some of these (yes, they ship international) and shipping wasn't too bad at about $10....
Always. Whoever comes first is getting it first We're in research for connecting Parallel LCD/VFD to USB and it looks like we have a solution that needs some Software
Well, click on my "email" icon over on the left and send me your mailing address and I'll send you one of these (CU20045SCPB-T23A ) and probably some other stuff, too. It's yours to keep - I just ask that you help me get it going serial (preferred) or parallel (that'll work, too). If you can furnish some wiring diagrams or relay the info to me, I will see to it that it gets posted at VFDWorld and that you receive full credit.
Shark: So, Dan_Dude's wiring diagram works OK? It's just a software problem? Did you hook up both +5v's and both grounds?
Klinkerstein: VFD's, in my opinion, look so much better than LCD's. They are "prettier". |

I have taken a look at Sharks Noritake-Specs. Looks like an RS232 with only one line (no handshake). That's dangerous, because STLCD may loose contact to the VFD and has no chance to detect this - but this may be solved by using BUSY as RTS-signal. Second: Emulating serial port behaviour on a parallel port is nearly impossible, as the timings cannot be guaranteed under multitasking conditions. Obviously, Dan-Dude tried this, too, and STLCD is conceptually unable to do this either. The next problem is, we need a MAX232 or something like this to convert serial port levels to TTL-Levels. I'm sure, the VFD doesn't like -12V on his Data Line. Building this Level-Shifter (very simple, indeed !) we can attach that VFD to a standard RS232-Port every PC has and get it running. More interesting, using an USB-to-RS232 Adapter, you can attach your VFD to any USB-Port Of course, building some extra Hardware is dangerous and may damage the VFD when not being extremely careful. The Levelshifter is fairliy easy (one IC, 4 Capacitors) but may be too complex for single-cell-brainers. Still interested ?
First off, do you have something against sharing your parallel pinout for the CU20045SCPB-T23A?
Jeez, serial hookup sounds complicated all of a sudden, eheh... As I mentioned earlier, on those very popular IEE Century 2 x 20 displays, it was just - connect 3 wires, make sure the jumpers were set right on the back (19200 baud, Intel, Normal), install the .ocx file and LCDC or VFD Thinger, make a couple of minor tweaks to the software and badda bing, badda boom, it ran no problem...
Sounds like the Noritake serial mode is not so user friendly .... I was hoping for a simple and direct serial port hookup, thinking that perhaps Dan_Dude had overlooked something...... If I understand you correctly, Noritake didn't quite get it to that point....
So, right back at ya: Still interested? |

If you like to, I will do my best to translate STLCD to english, so you can work with it a bit more efficiently - just say a word. Be warned, this software is written for purists, no really Dumb-Docs and no mouse-clicking-config. Proven by several users in this forum, STLCD seems to be the fastest (speaking of consuming CPU-cycles) and most robust LCD-Software yet.
Well, I think you could reach a wider audience (if that is your intention) by providing English support. Eventually, you may want to include many languages ala the way Alex did with MBM. I think the problem I've seen most often with some LCD programs is memory leaks. It's kind of ironic that the program can "tattle" on itself by showing growing memory usage! Some of the LCD software programs are OK but sort of "unfinished". Others promise great things to come but never arrive (Uller's LCDriver 2.0 comes to mind).
That said, there's more than a few of us that prefer VFD's over LCD's. VFD's can be found for cheap on Ebay and electronic surplus stores/websites. Noritake and IEE are the ones I see a lot of in the US. Both brands make "parallel only" models and bimodal (serial and paralllel) models. A lot of people (like myself) are not programmers, but can get one of these running no problem as long as there's support via an easy to read wiring diagram (diagram by me) (btw, do you have a parallel piinout for the CU20045SCPB-T23A?  ) and some software to run it. For parallel, the software can get by usually with just the HD44780 mode. But serial mode might be stickier, I don't know - like I said, I'm not a programmer. I do know LCDC depends on "definition files". (A while back, over here in the states, www.bgmicro.com had the huge IEE Century 2 x 20 VFD for sale for $20. Hundreds bought one of these, download the ".ocx" file, hooked up 3 wires: +5v, ground and serial-in, and with LCDC or VFD Thinger, were off and running in serial mode. Very easy).
I couldn't follow this thread except for the pictures.... Did Shark send the VFD to you, you got it running and then you sent it back to him? Tell you what, if you PM or email me your address, I will send you another CU20045SCPB-T23A to see if you can get it running in serial mode.... That is, if you're willing to try. It may not be easy, though. Dan_Dude was unsuccessful.....

That is cool! Dan_Dude mentioned to me today that someone needs to start mass producing a USB converter/controller...
Olaf wants to write the support for this controller in his STLCD software. I build the hardware. If you send us an example, we maybe support your VFD (as Olaf has time to do this ) If it is this Display: http://www.qscomp.cz/Pdf/CU24025ECPB-W1J-02.pdfit maybe works already as a HD44780 LCD.
I had the CU24025ECPB-U1J model. The only differences I can see between the two is in "operating temperature" and "luminance" so basically, they are the same. I think the "W1J" is probably the newer version of the "U1J". And, yes, it worked fine in "HD44780 mode"/paralllel with most LCD software including jaLCD's. Unfortunately (or fortunately depending on how you look at it), they sold out pretty quick at that price.....

Thanks for the replys!
Yes, I'm familiar with the www.vfdworld.com link. Dan_Dude (the webmaster @ vfdworld) and I have communicated about these displays... He had no success getting it to run in serial mode and mild success getting it to run in parallel mode - there were a few problems. Looking at the pictures in this thread, it looks like you guys got it going fine in parallel mode.... 
(By the way, if you scroll down the link, you'll see my name next to the Noritake 2 x 24 display. I found those displays for $3 each (!  !) at a website, bought 30 of them and sold them for cost to my modding friends that hang out at www.pheatonforums.com, eheh.... I've used jaLCD's with these and it works great....but I digress....)
Problem is, I've got several models of VFD's - most of them are parallel. This is one of the few that supports serial. I've been building cases with small motherboards lately and these small motherboards don't have a parallel port. That leaves my choices for adding a VFD very slim. There's the IEE Century 2 x 20 display (BGMicro.com) and that's about it. It's a little long and bulky for a small case. If I could find another display that runs in serial mode, that would be aces....
Anyhow, I would stilll appreciate a wiring diagram for parallel mode if someone has one...
BTW, I will try STLCD, thx for the link!

Hello - Does anyone here speak English? (I hope it is OK to speak English here)...
I don't speak German and am having a terrible time trying to navigate this site... An internet search led me to these forums.....
I have a couple of these displays. Has anyone been able to get one of these running in serial mode using the white 3-pin connector?
Parallel mode: Does anyone have a hookup diagram or pinout? It's a little confusing what with the technical documentation I've seen showing two +5v's and two Grounds on the 16-pin connector.... which to use?
Thanks in advance......
