Help identify lcd display on Smoothwall SWG700 [Edit: Portwell EZIO]

stephenw10

Hmm set the port speed manually and initialised the display…. still nothing coming back

Sending

printf "\376\010" > /dev/cuau1

Does correctly clear the display so commands are reaching the module as expected.

The spec is here:

There is a picture of that ribbon cable for the keypad.

Could also be that the serial cable is somehow not connected right.

stephenw10

I don't believe it's a problem with the ribbon cable as I expect to see 0x4f sent even if the keypad is disconnected. It could be the serial cable…. I don't think the display sends anything else we can check that with. Hmm...

A second tester could help here.

There is another thing, too. There is a "watchdog timeout" for custom characters if you do not send all 8 bitmaps. See Note 3 in the spec.

Send xFEx40. See if xFDx0E comes back…

stephenw10

Nothing from that either. I'll have to pull it out when I have time and check it.

I started a separate thread here. Hopefully we can get a tester or two.

hi fmertz,
is it possible to take 2.1.5 x64 and x32 eizo 300 driver.

please save me…

stephenw10

Upgrade! ;)

Really is there any reason you're still running 2.1.5?

You could compile the driver against FreeBSD 8.3 with some effort I expect.

@stephenw10 Can you reupload than hex file please think the forum movement killed it. Thanks

stephenw10

Sure here you go.

But you can use fmertz's driver directly now via lcdproc if you want.
