I have completed, still a few bugs to work out, a VFD controller driver.

there are a crapload of custom VFDs on ebay, about 130 of them from the same seller. they looked like they were designed for compact stereos, but were never employed. So i bought one to do a project with.

I used a mega163L, 4mhz, which is what I had on hand. I emulated the Noritake T23A command set for 1 main perpose, So i can use PC software LCDhype with a winamp plugin so i can display an FFT spectrum and song info on the display.

So far so good, i gotta work out a quirk with the LCDhype software. its scrolling the whole spectrum and text, because the commandset im emulating, this is emulated as a 1x24 display. if i somehow could emulate it as a 2x12, bar as the bottom 12, and text as the top 12, it would fix that mess. :) but not sur ehow to emulate rows. but i could work with a single row command emulation just fine. :)

any ideas? what do you think?

another pic and code.

If you want to do something like I am doing with this particular VFD, they can be had on ebay. VERY cheap.

I struggled for days to get the noritake 140x32 vfd glass we have working acording to the oddly worded datasheet. I thought I was the only guy in the world that didnt work at Noritake Tokyo that had ever figured it out. If you got all that to work on your own, then YOU DA MAN!

I got a nortake GU311 display which is like a 128x32 display. that think sucks. slower than garbage. LOL.

the problem with noritake displays, they use encapsulation. makes it uber slow. you cant just send 1 byte after the other. they encapsulate each frame.

It may be an unfinished project, but this [AVRfreaks Academy forum] topic
does comply with the New Project notification for projects in progress.

It is important, cluttering up this forum with irrelevant stuff devalues the proper content. Why do you think it was created in the first place?

It would be best if you reposted in the correct place.

Leon,

I'm pointing out, again, that the user/moderator posted guidelines are in conflict
with New Project admin managed message and that the AVR Freaks admins ARE
the highest authority as they have ultimate control.

Uhmm...bickering about the relevance of something with so many post including mine sounds like an excelent way to clutter up the place with irrelevant content...
