Depois de instalar e configurar o SO, instale o LIRC. Update the package index and upgrade the installed packages:
$ sudo apt update
$ sudo apt upgrade
Install the LIRC package and its dependencies:
$ sudo apt install lirc
Configure LIRC to work with your IR receiver by editing the LIRC configuration file:
$ sudo vi /etc/lirc/lirc_options.conf
Change the following line:
driver = devinput
to:
driver = default
Edit the LIRC hardware configuration file to match your IR receiver:
$ sudo nano /etc/lirc/hardware.conf
Uncomment the following lines and set the GPIO pin number that your IR receiver is connected to:
LIRCD_ARGS="--uinput --listen"
LOAD_MODULES=true
DRIVER="default"
DEVICE="/dev/lirc0"
MODULES="lirc_rpi"
GPIO_IN_PIN=<GPIO_pin_number>
Restart the LIRC service to apply the changes:
$ sudo systemctl restart lirc
Test the IR receiver by running the following command:
$ irw
