Yup. And... I am probably wrong about the parallel interface. John describes it well. I was a comm jock once a long time ago before these were made. But I don't remember my line-level stuff. It would be normal for it to be parallel in an internal design like this because it is faster to drive

Re: [neonixie-l] OT - 20 chr VFDs >blech

Most Arduino kits but the smallest ones (i.e.: Mini) and Raspberry Pi have enough GPIO pins available to do it without need to resort to serial to parallel. Of course you can use any of the I2C chips available too. My philosophy is to adhere as much as possible to the KISS principle. On

Re: [neonixie-l] OT - 20 chr VFDs >blech

This is accurate and great detail. I believe it is simpler than you might think. This is just a parallel interface (times two). The work is done with the shifters and the data is pumped via a parallel interface from the processor as in the original design. I am just a software guy, but once I

Re: [neonixie-l] OT - 20 chr VFDs >blech

Hi John, The scans you posted answer all of the questions. There is no "display controller" as you'd expect from the modern "fruit machine" displays. All we have on the board is latches and level shifters. pins 16,18,19 control a shift register (TL5812) to select the digit position to display

Re: [neonixie-l] OT - 20 chr VFDs >blech

Greetings John, I just want to thank you for posting these scans. I received my displays, and while i was very happy with the purchase, i was a little overwhelmed with the prospect of figuring out how to light 'em up. Thanks to you, i now have a solid basis from which to proceed. And i'd

Hi Keith, I just found out where my boards are. I got hit with some customs duty and I only just got a bill to say so today. My displays should be with me on Monday now as I’ve sent the government its due. The manual was sent out to me via second class post yesterday, so I might get it

Re: [neonixie-l] OT - 20 chr VFDs >blech

John, Great. Let me know when you get this. These boards look luscious. It looks like a parallel interface in, but the mapping of the pins would be tedious without manual/schematics. - Keith On Thursday, May 30, 2019 at 3:33:43 AM UTC-4, Nixcited delighted wrote: > > I have a complete

Re: [neonixie-l] OT - 20 chr VFDs >blech

I have a complete manual, inc. schematics, for Alvin G’s 'Dinosaur Eggs' on its way to me. This should be compatible with the VFD display boards. https://www.ipdb.org/search.pl?name=dinosaur+eggs=20=name=advanced Once I have the manual, I’ll scan the relevant pages and post them somewhere.

Re: [neonixie-l] OT - 20 chr VFDs >blech

I am not having much success with a schematic. I just wrote to another contact who may be able to help. I am also not having much success with delivery of the boards either. I received a note that they had cleared UK customs. I received a further message that they tried to deliver to me on

Re: [neonixie-l] OT - 20 chr VFDs >blech

I grabbed some, too. Did you find a datasheet or Alvin manual? It is a parallel interface but it'll be interesting to try and reverse engineer this. These are lovely display boards. On Wednesday, May 22, 2019 at 1:14:00 PM UTC-4, Jon D. wrote: > > John, > > I have a couple of these 20-digit

Re: [neonixie-l] OT - 20 chr VFDs >blech

Hi guys, Did anyone receive any of those boards from Down Under? I feel tempted to buy but I'm afraid the VFDs could be outgassed. The customs regulations in my country let me buy only one at a time so my success probabilities should be high for me to take the plunge... 86 USD for a

Re: [neonixie-l] OT - 20 chr VFDs >blech

Shwmae But. Hi John, I'm here! Looking at the picture of the display it looks like a parallel interface of some kind. There's a micro and ram on the board. I wonder if it's compatible with another pinball display ? Unlike the newer displays these do not appear to have any power supply onboard

Re: [neonixie-l] OT - 20 chr VFDs >blech

I don’t have a datasheet, nor do I have my displays yet. My main pinball man has drawn a blank on getting me a schematic and he’s been thorough. The manual is available from Marco in the US and the Australian seller also has manuals - https://www.pinballspareparts.com.au

I wonder are they individual displays all connected together or do they come apart? If they work it's kinda cool. Bill -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To unsubscribe from this group and stop receiving emails from it, send an
