Hello,
I’m trying to write the Adafruit ADXL343 demo sketch (Adafruit_ADXL343/sensortest.ino at master · adafruit/Adafruit_ADXL343 · GitHub) to an Adafruit Metro Mini, which is basically equivalent to an Arduino Uno.
My platformio.ini looks like this:
[env:uno]
platform = atmelavr
board = uno
board_build.mcu = atmega328p
;lib_compat_mode = off
;lib_ldf_mode = deep+
lib_deps =
adafruit/Adafruit ADXL343
adafruit/Adafruit Unified Sensor
While the resolver does find and download relevant libraries, during a run attempt it disregards them as incompatible:
$ bin/pio run -v
Processing uno (platform: atmelavr; board: uno; board_build.mcu: atmega328p; lib_deps: adafruit/Adafruit ADXL343, adafruit/Adafruit Unified Sensor)

However, the library.properties file in those library directories don’t appear to specify any limitation (they show architectures=*
, but I don’t know if that’s relevant).
Changing the compat_mode and ldf_mode settings don’t cause it to find those libraries acceptable.
Am I missing something? Switching to Windows and the Arduino IDE, I was able to flash the sketch successfully, so I think these libraries should be compatible.
