[lcd4linux] Strange behaviour of a BA63 Cashier-Display and failed self-test initiation through config

[Sven W. <zel...@ve...>]

Hello all!

I hope this list is still active, since there were no posts in almost a
month. I'll post anyway. :-)

After some experimenting (and cursing) :-) I have finally managed to
build myself an adaptor to connect my BA64-Display to my router. I've
checked the adaptor twice before connecting it. RTS/CTS as well as
RXD/CXD are connected, +12V I'm getting from inside the machine and all
ground is on the same potential (all connected!). So this should be fine.

Static data is displayed just fine, but as soon as it comes to changing
data, i.e. Uptime or data-troughput, it completely screws up. :-(

Example given:

Row 1:   Scroller with router name, circuit and IP-address
Row 2:   Router-Uptime

Both rows full length (20 colums).

It's hard to describe what the display does. I'll try anyway. The
changing seconds in the uptime are displayed in Row 1, either as last
digit, or they trail the scroller. (clear?) If not, I've recorded a clip
using my and a friend's cellphone. One is in the 3gp-format, the other
is MPEG4.

http://home.versanet.de/~zelgadis/video/VFD_BA63.3gp   ~280KB
http://home.versanet.de/~zelgadis/video/VFD_BA63.mp4   ~5.3MB

I've uploaded my complete configuration-file here:

http://home.versanet.de/~zelgadis/txt/lcd4linux.conf

So if you nice folks could check either file, see what my display does
and then (maybe) help me solve the problem, I'd be grateful.

For testing purposes, I've also tried the SimpleLCD-driver with the same
result.

Also, if I set the Seftest to 1 I don't get a selftest, but an error
when I start lcd4linux. Like this:

LCD4Linux is running on a fli4l-Router running Kernel 2.4.32. Version is
0.10.1-CVS. Since this is fli4l, I'm unfortunately stuck with this
version of LCD4Linux. I'm not into compiling myself... :-/

Any ideas? Any help is appreciated, 'cause I'm at the end of my rope here...
