Notes to make IR shield (made by LinkSprite) work in Raspberry Pi 3 (bought from Amazon [1]).
The vendor has some documentation [2] but that is not complete and sufficient for 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 (incomment if required)
dtoverlay=lirc-rpi,gpio_in_pin=18,gpio_out_pin=17
# Update the following lines in /etc/lirc/lirc_options.conf
# Update the following lines in /etc/lirc/lircd.conf
driver = default
device = /dev/lirc0
# Reboot before testing
$ reboot
$ sudo /etc/init.d/lirc start
# Check status to make lirc is running
$ sudo /etc/init.d/lirc status
# Populate lircd.conf
#
# this config file was automatically generated
# using lirc-0.8.6(default) on Fri Sep 10 22:02:46 2010
