platformio not handling assembly correctly? #58

Sorry to continue with the "this works under the Arduino IDE but not platformio" topics.

In this one, I'm using an FFT library from which is written in assembly. It looks like platformio does compile it into a library, but may skip a step:

amp@AMP-MBP-home:~/Dropbox/Arduino/ObjectLights/platformio [master]$ platformio run
Processing arduino_nano environment:
avr-g++ -o .pioenvs/arduino_nano/firmware.elf -Os -mmcu=atmega328p -Wl,--gc-sections -Wl,--start-group .pioenvs/arduino_nano/src/Sound.o .pioenvs/arduino_nano/src/SoundCLI.o .pioenvs/arduino_nano/src/SoundUnit.o -L.pioenvs/arduino_nano .pioenvs/arduino_nano/libDebug.a .pioenvs/arduino_nano/libffft.a .pioenvs/arduino_nano/libSerialCLI.a .pioenvs/arduino_nano/libRS485_non_blocking.a .pioenvs/arduino_nano/libSoftwareSerial.a .pioenvs/arduino_nano/libSPI.a .pioenvs/arduino_nano/libFastLED.a .pioenvs/arduino_nano/libHMTLTypes.a .pioenvs/arduino_nano/libPixelUtil.a .pioenvs/arduino_nano/libRS485Utils.a .pioenvs/arduino_nano/libSocket.a .pioenvs/arduino_nano/libMPR121.a .pioenvs/arduino_nano/libWire.a .pioenvs/arduino_nano/libGeneralUtils.a .pioenvs/arduino_nano/libEEPromUtils.a .pioenvs/arduino_nano/libEEPROM.a .pioenvs/arduino_nano/libHMTLMessaging.a .pioenvs/arduino_nano/libHMTLprotocol.a .pioenvs/arduino_nano/libFrameworkArduino.a -lm

Thanks! I've never tested PlatformIO with assembly files. Sorry 😞

Please upgrade your PlatformIO with new develop:
$ pip install

P.S: I've just added new lib Adafruit-LED-Backpack and you can compile with the several commands:

# init empty project and copy to "src" dir
$ platformio lib install 128
$ platformio run

You don't need to install Adafruit-GFX, this library has pre-defined dependency

After updating it looks good. Thanks for all the work you're putting into this, I'm pretty excited to be making the switch.

Also thanks for installing that library, although I'm not actually using it in this particular project, I just grabbed their code for the sound sensing ;)
