framework = arduino
Adding the option custom_sdkconfig in an [env] will compile the Arduino libraries using the sdkconfig settings
from the framework and adds the changes specified in custom_sdkconfig. After the compile run the Arduino project [env] is
compiled with the customized libraries.
Example: Switching off PPP modem support only for [env:esp32-no-PPP]
[env:esp32-no-PPP]
board = esp32dev
custom_sdkconfig = '# CONFIG_LWIP_PPP_SUPPORT is not set'

This platform supports two filesystem options:
- LittleFS (default) - Wear-leveling filesystem optimized for flash memory
- FatFS - Standard FAT filesystem with broad compatibility
FatFS is now fully integrated as a Python module, similar to LittleFS.
Quick Start:
[env:myenv]
board_build.filesystem = fatfsAvailable Commands:
pio run -t buildfs # Build FatFS image
pio run -t uploadfs # Upload FatFS image
pio run -t download_fatfs # Download and extract FatFS from deviceSee the arduino-fatfs example for a complete working example.
