# Appunti su ir-keytable (no LIRC)

<abstract>
Appunti di uso sul ricevitore IR GPIO e l'utility ir-keytable (senza LIRC Linux Infrared Remote Control)
</abstract>

Gli step per abilitare il funzionamento di un telecomando a raggi infrarossi con ir-keytable sono i seguenti:

* collegare il ricevitore hardware (TSOP48xx)
* installare e configurare il driver PIO 
* installare la utility ir-keytable
* configurare uno o piu' telecomandi

## Installazione hardware

Lo schema mostrato e' riferito al modello TSOP con portante a 38 kHz:

## Installazione driver GPIO

Per l'utilizzo di LIRC con un ricevitore TSOP e' necessario aggiungere/scommentare
il seguente codice nel file /boot/config.txt

<pre class="terminal">
#
# https://forum.libreelec.tv/thread/4413-7-95-1-lirc-not-working-correct-on-rpi/
#
dtoverlay=gpio-ir,gpio_pin=23,gpio_pull=1,rc-map-name=rc-rc6-mce
</pre>

e fare il reboot del sistema.

## Installazione  utility ir-keytable
<pre class="terminal">

# Remove LIRC from your system
% sudo apt-get purge lirc

# If the /etc/lirc folder exists on your system, remove that as well
% sudo rm -rf /etc/lirc

# install ir-keytable
sudo apt-get update && sudo apt-get dist-upgrade -y
sudo apt-get install ir-keytable -y
</pre>

## Configurazione telecomandi

ir-keytable e' un sistema molto piu' semplice quando comparato con LIRC, 
non richiede installazione di device drivers particolari perche' usa quelli del kernel mainstream 
che su RPI sono inclusi ed i cui DTS sono gia' presenti e, come gia' visto, configurabili su /boot/config.txt .

Il difetto principale e' che , rispetto a LIRC, il numero dei telecomandi gia' presenti e' molto ridotto e quindi, 
con tutta probabilita', occorrera' configurarli da zero.

### Test telecomando

Purtroppo per poter appurare quale protocollo supportoa il telecomando sotto test 
occorre andare per esclusione, abilitando dapprima tutti i protocolli disponibili:

<pre class="terminal">
pi@rpi-iw0hdv:~ $ sudo ir-keytable -v -t -p rc-5,rc-5-sz,jvc,sony,nec,sanyo,mce_kbd,rc-6,sharp,xmp

</pre>

Premendo i tasti del telecomando vengono visualizzati  i codici ricevuti (questo nel caso il protocollo sia supportato).
Eliminando i protocolli uno ad uno , si riesce ad indentificare quello corretto (nel nostro esempio il sony)..

<pre class="terminal">
...
...
1508273202.082676: event type EV_MSC(0x04): scancode = 0x1f0026
1508273202.082676: event type EV_SYN(0x00).
</pre>

se, come nell'esempio, non compare il nome del tasto, la tabella di decodifica non supporta il telecomando.La cosa piu' semplice e' cercare 
se in qualcuno dei telecomandi supportati compare lo scancode:

<pre class="terminal">
grep -iH '0x1f0026' /lib/udev/rc_keymaps/*
</pre>

Se la ricerca e' vana, occorre creare autonomamnnete la mappa scan scode -> tasto, premendo tutti i tasti di interesse del proprio telecomando
ed annotando 


### Creazione file di configurazione

Il formato del file di map e' il seguente:

<pre class="terminal">
pi@rpi-iw0hdv:~ $ cat robophilo.txt
# table robophilo, type: sony
0x1f0026 KEY_1
0x1f0027 KEY_2
0x1f0028 KEY_3
0x1f0029 KEY_4
0x1f002a KEY_5
0x1f002b KEY_6
0x1f002c KEY_7
0x1f002d KEY_8
0x1f002e KEY_9
0x1f002f KEY_SERVO
0x1f0030 KEY_0
0x1f0031 KEY_POSITION
</pre>

la prina riga contiene il nome simbolico del telecomda ad il protocollo, seguono le corrispomdeze scancode / tasto.

Tutti i codici tasto ammessi sono visualizzabili con il seguente comando:
