Step by Step ir-serial mit ir-keytable

Die hier beschriebene Konfiguration ist inzwischen in das Setup übernommen worden.

        Repeat delay = 500 ms, repeat period = 125 ms

hier sieht man nur das device der DVB Karte - dieses soll allerdings nicht genutzt werden.

device anlegen

Da serial nicht automatisch erkannt werden kann muss es manuel getriggert werden:

festlegen an welchem COM Port es angeschloßen ist(hier com1)

setserial /dev/ttyS0 uart none

nun die Treiber laden:

modprobe serial-ir

dmesg sagt nun:

das Device rc1 ist nun vorhanden aber es empfängt noch keine Daten, da das Protokol falsch ist.

device test mit evtest

BVDR> evtest
No device specified, trying to scan all of /dev/input/event*
Available devices:
...
/dev/input/event14:     cx88 IR (TeVii S464 DVB-S/S2)
/dev/input/event15:     Serial IR type home-brew
Select the device event number [0-15]:

event15 ist unser Empfänger er hat aber noch kein passendes Protokoll

evtest /dev/input/event15

liefert noch keine TASTEN beim drücken.

Protokoll ermitteln

zwei möglichkeiten.

Protokolle einzeln laden

BVDR> ir-keytable -s rc1 -p NEC
Protocols changed to nec

NEC ersetzen durch den Namen des zu testenden Protokolls in unserem Fall sagt ir-keytable:

Supported protocols: lirc rc-5 rc-5-sz jvc sony nec sanyo mce_kbd rc-6 sharp xmp

nun mit evtest Testen:

Es sieht gut aus - wir haben scan codes ABER noch keine Zuweißung.

EINFACH ALLE Protokolle laden

Man lädt einfach mit -p alle Protokolle die laut ir-keytable unterstützt werden aufeinmal rein:

BVDR> ir-keytable -s rc1 -p lirc -p rc-5 -p rc-5-sz -p jvc -p sony -p nec -p sanyo -p mce_kbd -p rc-6 -p sharp -p x
mp
Protocols changed to lirc rc-5 rc-5-sz jvc sony nec sanyo mce_kbd rc-6 sharp xmp

Damit sollten aufjedenfall wieder keycodes funktionieren!

Wie auf bei Möglichkeit eins muss man diese nun einem Key zuweißen oder man hat bereits eine map datei und lädt diese.

scan codes einem Key zuweisen

nun haben wir scan codes also weisen wir diese nun den Tasten zu: Beispiel mit Taste 1. Bei Taste 1 kommt folgende evtest Ausgabe:

Event: time 1523714338.384568, type 4 (EV_MSC), code 4 (MSC_SCAN), value 11
Event: time 1523714338.384568, -------------- SYN_REPORT

der scan code ist somit 11 und dieser muss nun Key_1 zugewiesen werden.

dazuerstellt man eine Datei in /etc/rc_keymaps/name_der_remote und füllt diese mit folgender Syntax:

0x[SCANCODE] LEERZEICHEN [KEY]

also für uns Beispiel:

0x11 KEY_1

Speichern fertig!

scan codes Key zuweisung testen

Nun testen wir diese zuweißung indem wir die map auch mit laden -w.

ir-keytable -s rc1 -c -p NEC -w /etc/rc_keymaps/rc-test-nec
Old keytable cleared
Wrote 1 keycode(s) to driver
Protocols changed to nec

es wurde ein keycode geladen (klar wir haben nur einen hinzugefügt). Dabei habe ich bewusst das richtige Protokoll eingefügt.

ir-keytable sieht nun so aus:

 ir-keytable
Found /sys/class/rc/rc1/ (/dev/input/event15) with:
        Driver serial_ir, table rc-rc6-mce
        Supported protocols: lirc rc-5 rc-5-sz jvc sony nec sanyo mce_kbd rc-6 sharp xmp

        bus: 25, vendor/product: 0001:0001, version: 0x0100
        Repeat delay = 500 ms, repeat period = 125 ms

evtest sagt nun:

es kann schon KEY_1

Event code 2 (KEY_1)

das testen wir natürlich sofort in dem wir auf der Fernbedienung Taste 1 drücken:

Testing ... (interrupt to exit)
Event: time 1523715061.010631, type 4 (EV_MSC), code 4 (MSC_SCAN), value 11
Event: time 1523715061.010631, type 1 (EV_KEY), code 2 (KEY_1), value 1

Event: time 1523715061.402358, -------------- SYN_REPORT ------------

alles wie gewollt. So geht man nun weiter vor, bis man alle Tasten angelernt hat, oder man lädt eine bereits enthaltene datei aus /etc/rc_keymaps oder /lib/udev/rc_keymaps

Anpassungen für den RPi

In der Datei /boot/config.txt muss jetzt “dtoverlay=lirc-rpi” geändert werden in:

dtoverlay=gpio-ir,rc-map-name=rc-hauppauge

Weiterhin ist in der /etc/rc_maps.cfg die Zeile “ir-kbd-i2c rc-hauppauge /etc/rc_keymaps/rc-hauppauge” wie folgt auszutauschen:

gpio_ir_recv             rc-hauppauge               /etc/rc_keymaps/rc-hauppauge
