Getting lirc to work with Raspberry Pi 3 (Raspbian Stretch)
Raw
lirc-pi3.txt
- I bought IR shield (made by LinkSprite) for Raspberry Pi 3 from Amazon [1]. The vendor has some documentation [2]
but that doesn't work completely in Raspbian Stretch. Following are the changes that I made to make it work.
$ sudo apt-get update
$ sudo apt-get install lirc
# Add the following lines to /etc/modules file
lirc_dev
lirc_rpi gpio_in_pin=18 gpio_out_pin=17
# Add the following lines to /etc/lirc/hardware.conf file
LIRCD_ARGS="--uinput --listen"
LOAD_MODULES=true
DRIVER="default"
DEVICE="/dev/lirc0"
MODULES="lirc_rpi"
# Update the following line in /boot/config.txt
dtoverlay=lirc-rpi,gpio_in_pin=18,gpio_out_pin=17
# Update the following lines in /etc/lirc/lirc_options.conf
driver = default
device = /dev/lirc0
$ sudo /etc/init.d/lircd stop
$ sudo /etc/init.d/lircd start
# Check status to make lirc is running
$ sudo /etc/init.d/lircd status
# Reboot before testing
$ reboot
# To test if lirc driver is working
$ sudo /etc/init.d/lircd stop
$ mode2 -d /dev/lirc0
