PfSense on a Celestix S-X MSA 4000
-
Has anybody gotten the screens to work under pfSense? I just picked one up, got it installed, and would love for the LCD / Jog to do something other than –------------ SYSTEM READY -------------
-
Got it working!
Hi yeyus,
Would it be possible to post the code you used to get the display working please?
Thanks!

The alert LED is GPIO. Here's the linux source. Please share back if anyone can get it to work on FreeBSD.
Hi twisted2k3,
How did you determine the IOADDR (base address?) of the GPIO controller? I am trying to recompile for Linux with an WSA-4200 which has a different motherboard to the MSA…
Thanks!
-
Sorry to bring back an older thread but did you guys ever get this working?
-
Yeah so in Linux it is recognised and creates /dev/hidraw0. That doesn't happen in FreeBSD so you would need to address the USB device directly or create some other driver.
The GPIO LED is probably controllable though.

I was able to find this out there not sure if it would help:

Unfortunately it doesn't. It still uses the same Linux driver:
def lcd_display(message, line=1): message = str(message) line_selection = "\x00" if line == 1 else "\x01" preamble = "\x02\x00\x00{0}\x28\x00\x00\x00".format(line_selection) endpad = "\x20"*(40-len(message)) data = preamble + message + endpad with open("/dev/hidraw0", "w") as lcd: lcd.write(data)Addresses /dev/hidraw0.
Interesting that that driver is in VyOS though…. if it's a standard Linux driver we might be able to see some clues.

dmesg on system yields:
ukbd0: <vendor 0="" 2="" 0x0cb6="" keyboard="" +="" lcd,="" class="" 0,="" rev="" 1.10="" 1.00,="" addr="">on usbus1</vendor>

Looks like there is something testable with the information published this far.
The Python code shows a sequence of hex codes
The device is known
The BSD shell has the printf built-in, and it accepts codes on octal format.
So, to hexadecimal 0x20 becomes octal \40
Try something like this:
printf "\02\00\00\61\50\00\00\00Some Message" > /dev/ukbd0Try this for line 2:
printf "\02\00\00\62\50\00\00\00Some Message" > /dev/ukbd0 -
So something interesting happened. I rebooted the machine and now dmesg shows:
ukbd1: <vendor 0="" 2="" 0x0cb6="" keyboard="" +="" lcd,="" class="" 0,="" rev="" 1.10="" 1.00,="" addr="">on usbus1
This is what I get while running the printf command
[2.3.5-RELEASE][root@pfSense.geek.local]/: printf "\02\00\00\61\50\00\00\00Some Message" > /dev/ukbd1
/dev/ukbd1: Device busy.</vendor> -
Hmm, that's not good. Changing device names makes it that much harder to work with even we could get it to accept any input. :-\

Good reading here:
https://www.freebsd.org/cgi/man.cgi?query=ukbd&sektion=4
Seems like we would need that character device. Once it shows as /dev/kbd1, that printf should be directed to it. Worth a try…

I’m relatively new to pfsense here and have read that. How would I go about compiling that in the kernel and config to test? May need a little guidance here but looks like we’re getting somewhere here!

Actually, looking at the Linux device, it suggests it is a raw device. Maybe the character device is not needed.
Maybe it needs to be initialized read/write:
exec 3<> /dev/ukbd1 -

Missing name for redirect.
