Problem:
When compiling your PlatformIO firmware, you see an error message like
In file included from .pio/libdeps/esp32dev/Adafruit BusIO/Adafruit_BusIO_Register.h:2:0, from .pio/libdeps/esp32dev/Adafruit INA219/Adafruit_INA219.h:21, from .pio/libdeps/esp32dev/Adafruit INA219/Adafruit_INA219.cpp:31: .pio/libdeps/esp32dev/Adafruit BusIO/Adafruit_SPIDevice.h:6:17: fatal error: SPI.h: No such file or directory ************************************************************* * Looking for SPI.h dependency? Check our library registry! * * CLI > platformio lib search "header:SPI.h" * Web > https://platformio.org/lib/search?query=header:SPI.h * *************************************************************
Solution:
Add SPI
to the lib_deps
in platformio.ini
, for example, before:
lib_deps = adafruit/Adafruit INA219 @ ^1.1.1
After:
lib_deps = adafruit/Adafruit INA219 @ ^1.1.1 SPI
and then recompile.
