If you are using a GPIO IR receiver. You should only need to edit the /flash/config.txt so that dtoverlay=lirc-rpi is not commented out. Then un install lirc if you installed it. Then put your RC-5 lircd.conf in the /storage/.config directory.Forget about all of that old fashioned stuff.
I'm using GPIO IR receiver for recording IR remote buttons but I am facing inconsistency to record and execute remote key using LIRC. My question is if we can use remote key operation in my code via IR keytable approach, if yes kindly help and provide steps to perform same.
