Finally I found my way... even mangaged to assign a double function to
the IQAudio push button:
1. installing sbpd
2. creating two bash scripts:
*phono.sh:* Short press powers up the Denon amp and starts playback of
the Zero's streaming URL, via main LMS Raspi (... .135)
Code:
--------------------
#!/bin/sh
telnet 192.168.50.135 9090 <<EOF
aa%3Aaa%3Acd%3A84%3A4c%3A59 playlist play
http%3A%2F%2F192.168.50.108%3A9100%2FS32_LE%2F44100%2F2%2FM
aa%3Aaa%3Acd%3A84%3A4c%3A59 mixer volume 50
quit
EOF
--------------------
*shutdown.sh:* Long press starts shutdown
Code:
--------------------
#!/bin/sh
sudo /sbin/poweroff
exit 0.
--------------------
3. putting
Code:
--------------------
sbpd b,27,SCRIPT:/home/tc/phono.sh,2,0,SCRIPT:/home/tc/shutdown.sh,1000
--------------------
as User command #3 in PCP.
Seems to work nicely, even if I'm sure that there are more elegant ways
to achieve this goal ;)
Now I'll try to connect another push button to GPIO3 - GND. As far as I
understand, this should power up the zero from standby, adding
Code:
--------------------
dtoverlay=gpio-shutdown,gpio_pin=3, active_low=1,gpio_pull=up
--------------------
to config.txt
