Optrex GLCD w/ NJU6676 issues |

Has anyone incorporated an Optrex GLCD with the NJU6676 controller before? I'm trying to communicate with an Optrex F-51852 and it's giving me an ulcer. Optrex support has been anything but.
All I'm after is a working init routine and a connection diagram that uses the parallel comm mode (so I can confirm my h/w). I've used, word for word, the init routine that Optrex claims to work and it won't. The display is totally dead, but I can communicate with the NJU6676.
I'm forced to use this particular display because F-51553 seems to be discontinued. That display uses the SED controller and it has easy to get up and running. The frustrating thing is that these two controllers are supposed to be nearly identical, save for the one difference noted on the second page of this document: http://www.apollodisplays.com/pdf/NJU6676vsS1D15605_E.PDF I've incorporated the extra 'driver on (0xE7)' command, but still nothing.
Any thoughts? |

PCM, if there was an emoticon for bow-down-and-worship-you-as-a-google-god, I'd surely include it.
Unfortunately, both versions of the h/w from the links you provided and the code that you miraculously dug up haven't helped. The crumbs that an optrex app engineer gave to me more or less matched everything in the links. I've tried countless variations of init code - all with the same result. The display doesn't properly init.
I put in ANOTHER request for information to Optrex and will see what develops. I'm seriously starting to hate Optrex. |
