I have a Futaba NA202MD13AA vacuum fluorescent display. It is a nice 20x2 display module with 2x Oki MSC1162A chips and one MSC1164 chip. They are available very cheaply at Prime Electronics.
These displays were apparently custom made for NCR, and I can find no programming information for the module as a whole, except for what is at this site.
Between that very high-level information and the datasheet on the (MS)C1162A, I've written some code for my Arduino (ATmega168), but I cannot get the the display to work. Nothing shows up. I'm pretty sure the display itself is functional because occasionally when I interrupt the microcontroller, I get some pixels lit on the display...just got lucky with spurious signals.
The module has a 10-pin socket, with the lines duplicated. According to the OVC site linked above the lines are Vcc, Gnd, Clock, Data, and Enable.
It appears that you need to clock in the raw bits for each column...there is no high level interface.
Does anybody have experience with writing code to interface with a similar display? I've pulled out what little hair remains, but I cannot figure out what I'm doing wrong!
I'd really appreciate some help from the hive mind.
