lcd4linux 2 Displays am RPi möglich

nicovanorton

Hallo ZD-Gemeinde,

ich nutze ein Rpi mit einem linkdelight (pearl) Display. Das funktioniert auch alles gut.

Dieses 1. Display hat die USB Serial: 1

Ich will nun ein 2. Display nutzen, gleicher Bautyp mit USB Serial: 2.

Die beiden lcd4linux.conf Dateien habe ich entsprechend angepasst.

Ich will nun lcd4linux jeweils manuell starten:

/usr/sbin/lcd4linux -f /etc/lcd14linux.conf -vv -p /tmp/lcd1.pid >/tmp/lcd1Start.log

/usr/sbin/lcd4linux -f /etc/lcd24linux.conf -vv -p /tmp/lcd2.pid >/tmp/lcd2Start.log

Bekomme aber nur leider einen angesprochen, der zweite ist dunkel

Beide Displays sind gepatcht. Bevor ich logs poste, die Frage: ist es genrell möglich 2 Displays am Rpi zu betreiben?

Merci
NvO

Du kannst es mal damit versuchen die Displays mit udev fest zu verlinken

nicovanorton

Habe ich auch schon gemacht und in der config /dev/display1 bzw. /dev/display2 angegeben.

in udev/rules.d habe ich den link

es scheint mir eher so, dass lcd4linux nicht 2x gestartet werden kann ?!?!?!?!??

**BurnStar**

doch kann es.
Aber die Binary muss verschieden benannt sein.
lcd4linux1 / lcd4linux2 sollte gehen.

nicovanorton

so, habe die ursprüngliche lcd4linux kopiert und 1 x lcd14linux genannt mit 755 und 1 x lcd24linux mit 755 genannt.
getrennt gestartet, aber es bleibt immer noch das eine Display dunkel.
Er starte auch nur die erste PID, dies sehe ich in var/run oder im Pfade, den ich angebe. Die zweite Instanz/Prozess startet er nicht?
Muss ich noch etwas kompilieren?
Kann gerne auch logs senden.

Ich habe weiter geforscht

Ich glaube es ist ein Treiber Problem, bzw. bei der Zuweisung der Serials zu den Displays.

Der dpf Treiber ist doch in der binäry selber drin
Mit Deiner udev Regel kann was nicht stimmen
poste mal die Ausgaben von

Ich habe ja zwei Displays am Bus 001  004 und 005

Das erste Display:

Code

[FONT=Menlo]lsusb -v -s 001:004 | egrep "idVendor|idProduct|iManufacturer|iProduct"[/FONT][FONT=Menlo]  
 idVendor           0x1908 GEMBIRD[/FONT]
[FONT=Menlo]  idProduct          0x0102 [/FONT]
[FONT=Menlo]  iManufacturer           2 hackfin[/FONT]
[FONT=Menlo]  iProduct                3 USB-Display
[/FONT]

Das zweite Display:

Code

[FONT=Menlo]lsusb -v -s 001:005 | egrep "idVendor|idProduct|iManufacturer|iProduct"[/FONT][FONT=Menlo]  
 idVendor           0x1908 GEMBIRD[/FONT]
[FONT=Menlo]  idProduct          0x0102 [/FONT]
[FONT=Menlo]  iManufacturer           2 hackfin[/FONT]
[FONT=Menlo]  iProduct                3 USB-Display
[/FONT]

Bei der udev Regel muss ich ja dann zwangsläufig über iSerial gehen, da alles andere ja gleich ist.

Code

[FONT=Menlo]lsusb -v -s 001:004 | egrep "iSerial"[/FONT][FONT=Menlo]  
iSerial                 1 001[/FONT]

und

Code

[FONT=Menlo]lsusb -v -s 001:005 | egrep "iSerial"[/FONT]
[FONT=Menlo]iSerial                 1 002

starte ich die erste lcd1linux wird das richtige Display angesprochen,

beim zweiten schlägt es fehl!

reboote ich das zweite Display und starte lcd2linux mit entsprechender config-Datei dann funktioniert es, vermutlich dann wieder nicht auf dem anderen.

In der Config habe ich Port 'usb1' und in der anderen config 'usb2' eingetragen. Warum udev nicht klappt ?!?!?!

Was aber auffällt:

Jemand noch eine Idee?

Tja, scheint irgendwie nicht zu funktionieren mit zwei identischen Displays.

Projekt abgebrochen, bzw. zurückgestellt. Muss ich halt nur ein Display nutzen.

Fall jemand das am laufen hat gerne auch per PN oder hier.
