I moved my project from Arduino to PlatformIO earlier this year as
I am compiling my project for two similar boards: Sparkfun RedTurbo and Adafruit Itsy Bitsy M0.
For both these the compiled uf2 file was, in March, 121k. I have just made a small update by deleting one line of code and recompiled. Now the Sparkfun code/image is still 121k but the Adafruit is 149k !
Where did 28k of code come from? What might cause this and how can I track it down?
I am concerned that a library or libraries have been updated and bloated the code. These are the library includes:
“Arduino.h” , “delay.h”, <Wire.h>, <Time.h>,<TimeLib.h>,<Timezone.h> https://github.com/JChristensen/Timezone
<SPI.h> ,<Adafruit_SPIFlash.h> //use older version 2 0 2
Any advice would be welcomed.
