From 3d04b1ccfe66b0cb56e16963ca16aea00f28290f Mon Sep 17 00:00:00 2001 From: Leon Anavi Date: Wed, 24 Jun 2020 12:51:03 +0300 Subject: rpi-config: Add ENABLE_IR variable for infrared Users who want infrared device tree overlays gpio-ir and gpio-ir-tx to be set in config.txt can now easily do it through variable ENABLE_IR, for example in local.conf: ENABLE_IR = "1" By default the GPIO pin for gpio-ir is set to 18 and the pin for gpio-ir-tx is 17. Both pins can be easily changed by modifying variables GPIO_IR and GPIO_IR_TX (for example in local.conf).
