Install lirc :
pi@moode:~ $ sudo apt update
pi@moode:~ $ sudo apt install lirc
Find setting for NAD:
pi@moode:~ $ irdb-get find nadmorgan's_daytona/Tornado.lircd.conf
nad/451.lircd.conf
nad/AVR2.lircd.conf
nad/AVR2.lircd.conf
nad/CDP-5425.lircd.conf
nad/RC512.lircd.conf
nad/SR6.lircd.conf
nad/SR712.lircd.conf
Ok, i choose SR6 (NAD_SR712 seems working also):
nad/451.lircd.conf
nad/AVR2.lircd.conf
nad/AVR2.lircd.conf
nad/CDP-5425.lircd.conf
nad/RC512.lircd.conf
nad/SR6.lircd.conf
nad/SR712.lircd.conf
Ok, i choose SR6 (NAD_SR712 seems working also):
pi@moode:~ $ irdb-get download nad/SR6.lircd.conf
Downloaded https://sourceforge.net/p/lirc-remotes/code/ci/master/tree/remotes/nad/SR6.lircd.conf as SR6.lircd.conf
and copy to etc folder:
pi@moode:~ $ sudo cp SR6.lircd.conf /etc/lirc/lircd.conf.d/
( or downloard lirc remote setting for NAD (325 use SR5 but SR6 seems working..) :
wget http://lirc.sourceforge.net/remotes/nad/SR6
)
Setup GPIO
GPIO 22 is used to transmit remote code by a simple NPN transistor and an IR LED:
Q1 ie.: 2N2222, R1 could be 4K7 and R2 100
IR LED can be salvaged from an old remote control.
Edit /boot/config.txt and add GPIO output line at the end :
pi@moode:~ $ sudo nano /boot/config.txt
dtoverlay=gpio-ir-tx,gpio_pin=22
Setup LIRC
Edit /etc/lirc/lirc_options.conf as follows by changing these two lines:
pi@moode:~ $ sudo nano /etc/lirc/lirc_options.conf
###driver = devinput
driver = default
driver = default
Remove suffix .dist from /etc/lirc/lircd.conf.dist
Enable the service:
pi@moode:~ $ sudo systemctl enable /etc/systemd/system/amplifierOn.service
pi@moode:~ $ sudo cp /etc/lirc/lircd.conf.dist /etc/lirc/lircd.confReboot
pi@moode:~ $ sudo rebootTest by sending code to NAD
First you check your hardware using your smartphone camera, IR codes are visible.
Send 100 times the code KEY_POWER:
pi@moode:~ $ irsend SEND_ONCE NAD_SR6 KEY_POWER -#100
You should see the IR LED flashing for 1 or 2 seconde
Turn on the amplifier after booting with a service !
pi@moode:~ $ sudo nano /etc/systemd/system/amplifierOn.service[Unit]
Description=Set up amplifier
After=lircd.service
[Service]
Type=oneshot
RemainAfterExit=true
ExecStart=/usr/bin/irsend SEND_ONCE NAD_SR6 KEY_POWER -#3
ExecStop=/usr/bin/irsend SEND_ONCE NAD_SR6 KEY_SLEEP -#3
[Install]
WantedBy=multi-user.target
Make this file executable:
pi@moode:~ $ sudo chown root:root /etc/systemd/system/amplifierOn.service
pi@moode:~ $ sudo chmod 666 /etc/systemd/system/amplifierOn.service
pi@moode:~ $ sudo chmod 666 /etc/systemd/system/amplifierOn.service
Save and test the service:
pi@moode:~ $ sudo systemctl start /etc/systemd/system/amplifierOn.serviceEnable the service:
pi@moode:~ $ sudo systemctl enable /etc/systemd/system/amplifierOn.serviceIf you got an error like :
Failed to start etc-systemd-system-amplifierOn.service.mount: Unit etc-systemd-system-amplifierOn.service.mount not found.
Just reboot and check service status:
pi@moode:~ $ sudo systemctl status amplifierOn.service
That should return something like:
● amplifierOn.service - Set up amplifier

| Which indicates that everything is working normally... if not... good luck ! |
