[Nevermind - These displays don't work with the SID]

9 posts in this topic

EDIT:  Nevermind - according to Altitude these displays don't work with the MB6582 boards without some driver hacking...  See his posts below.

Anyone interested in a group buy from Noritake-vfd.com?  They have great sales on a pretty regular basis, and right now 20x4 VFDs are on sale for $18.  Just so happens I have to buy a 20x4 for the SID PCB I just ordered..

 

CU20045-UW5A - 20x4 VFD - $18

They're very nice displays - I have 40x2's on my SEQ and they are great.  Very fast updates.

 

I'm happy to run a buy, but if someone in the states wants to do it, it would be significantly cheaper.  Noritake ships from the US, I think shipping is about $10 within the US for a small-ish order.  Shipping to Canada would mean higher shipping costs + the possibility of import taxes on a large order.

 

The picture below is a little blurry, these displays are very sharp - much sharper than it looks in the picture below.  Really bright too.

Looks like there's code for it already though - this one is the just the international fonts version of the one Hawkeye talks about in this thread:

 

...what type of display do you have?

Im interested in one, I've recently orders MB-6582 PCBs.

The spec says that it's HD44780 compatible so I don't understand why it would need a custom driver.

Yeah, my 40 x 2's worked out of the box...  But that other thread does say that there were issues with the UWQ5J version on the SID.  More discussion here:

 

Hawkeye got his working though, and the code is there.

He got it working on a bare core without the CS (I sent him one to try to sort it out), I could duplicate that here as well but it crashes if you connect it to a MB6582 mainboard, you get garbled display once you start using the controls it will eventual go out.  Someone with time, a MB6582 mainboard, and knowledge of writing drivers may figure it out.  It's not the same thing Hawkeye used in his.

 

I got very excited about this as well and bought 5 but they do NOT work with any existing driver.  If you want to give it a go, I'll send you one, just pay shipping

Oh...  That's a drag.  Thanks for clarifying though.

 

is it just the MB6582 that it doesn't work with?  ...or is it also problematic with the newer core based MIDIbox projects?

Confirmed, it is difficult... It works fine in my MB6582, but not in Altitudes, despite identical codebase - sth is different. It works fine on a bare 8-bit core, though.

And I think it should be possible to get it working in 32-bit land, as well. The price is great, but only worth the hassle if you are ready for some PIC assembler headaches :-).

Many greets,

Peter

Definitely not ready for any PIC assembler headaches.  Haha.  Thanks for confirming.
