Summary config LIRC 0.10.1-5.2 as Transmitter and Receiver for Raspberry (Raspbian or DietPi) with Kernel 4.19 based on elmicha comment on 30 May 2019

Steps to setup:

1. copy all files from this repo to your Raspberry
2. install patched and builded LIRC as it does here for 4.19 kernel

cd ./lirc-patched
sh ./deps-install.sh
sh ./lirc-install.sh // this will fail it's normal

3. run sh lirc-setup.sh to copy all files at needed destination
4. add two lines into /boot/config.txt or /DietPi/config.txt

dtoverlay=gpio-ir,gpio_pin=17
dtoverlay=pwm-ir-tx,gpio_pin=18

5. reboot

Instruction to wire

• Your IR-receiver signal pin should be connected into GPIO-17
• Your IR-transmitter should be connected into GPIO-18
• IR-led circuit and connection to Raspberry

Testing

• open first ssh terminal for Raspberry and run journalctl -fu lircd
• open second ssh terminal for Raspberry and run irsend --device=/var/run/lirc/lircd-tx SEND_ONCE TEST KEY_0
• success result you should see at your first ssh session

Inspect IR

To check supported IR and enabled protocols run sudo ir-keytable, to enable all possible protocols run sudo ir-keytable -p all -t -v

Known issues

• Send and Receive doesn't work from the same Raspberry device, in my case i tested with Raspberry Zero, but if we use two separate devices it works
