Help identify lcd display on Smoothwall SWG700 [Edit: Portwell EZIO]
-
Hmm, nothing coming back at all. I would expect to get back 0x4f every time if the keypad was disconnected for example.
Port somehow open write only?
-
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:
http://drivers.portwell.com/CA_Manual/EZIO/EZIO-FINAL.PDF
There is a picture of that ribbon cable for the keypad.
Could also be that the serial cable is somehow not connected right.
-
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…
-
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…
-
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.

Thanks works Perfect! ;)

@stephenw10 Can you reupload than hex file please think the forum movement killed it. Thanks
-
Sure here you go.
But you can use fmertz's driver directly now via lcdproc if you want.
