Quick update for the RaspIR post I made a while back.
After updating the Linux kernel on my Raspberry Pi a few days ago and rebooting,
I was met with the unfortunate scenario of being unable to turn my lights on and
off. After a few hours of furious Googling, it turns out that the lirc-rpi
module hasn’t made it into 4.19, instead gpio-ir and gpio-ir-tx are
recommended to replace it.
This necessitates a very small change to get it working again, altering
/boot/config.txt:
1dtoverlay=gpio-ir-tx,gpio_pin=27
Unfortunately this only enables a single device for sending (/dev/lirc0).
I’m still investigating how best to re-enable receiving IR input. By the sounds
of things (see here),
more work is required to maintain compatibility with LIRC’s irrecord and gpio-ir.
Hence, I think I may have to do a complete rewrite without using LIRC and using
e.g. ir-ctl and ir-keytable. But that’s something for another day.
