Morning JackOfAll,
In setting up the default operation of lirc-rpi we are using the
documentation /mnt/mmblck0p1/overlays/README
Code:
--------------------
Name: lirc-rpi
Info: Configures lirc-rpi (Linux Infrared Remote Control for Raspberry Pi)
Consult the module documentation for more details.
Load: dtoverlay=lirc-rpi,<param>=<val>
Params: gpio_out_pin GPIO for output (default "17")
gpio_in_pin GPIO for input (default "18")
gpio_in_pull Pull up/down/off on the input pin
(default "down")
sense Override the IR receive auto-detection logic:
"0" = force active-high
"1" = force active-low
"-1" = use auto-detection
(default "-1")
softcarrier Turn the software carrier "on" or "off"
(default "on")
invert "on" = invert the output pin (default "off")
debug "on" = enable additional debug messages
(default "off")
--------------------
This looks like a very bad choice for the default value. Are there any
recommendations that don't interfere with commonly used boards, or do we
just set it to "25" as it is the most common.
regards
Greg
