      Configure the default bit rate for the UART console.

      The resulting UART setting will be xxx-8N1, where xxx represents the
      chosen bit rate.

  help
      Enables auto-baud detection for the UART console.

      By typing a few characters into the console shortly after boot,
      NodeMCU can automatically detect your terminal settings and
      adjust accordingly.

      If you are doing advanced things with the console, you may want
      to disable this feature.

      Enable debugging output via NODE_DBG(). This is VERY chatty.

  bool "Enable NODE_ERR() output"
  default "y"
  help
      Enable error reporting via NODE_ERR().

      It is recommended to leave this enabled - if it ever produces output,
      something has gone seriously wrong and you probably want to know about
      it.

config LUA_EMBED_LFS
  bool "Embed LFS as part of the NodeMCU firmware"
  default "n"
  help
    The LFS (Lua Flash Store) normally has its own partition entry, and can
    can be replaced at will. Optionally, the LFS can instead be permanently
    embedded into the NodeMCU firmware image itself. This can be useful for
    scenarios where over-the-air firmware upgrades are needed to also
    bundle Lua code. The major downside is that once embedded, the LFS can
    no longer be changed, as doing so would break the firmware checksums
    and signatures and leave the system unable to boot.

    The default option is to not embed the LFS, in which case LFS is
    looked for in a partition of type 0xC2 and subtype 0x01.

    To embed LFS data into firmware, use:
      ./tools/embed_lfs.sh /path/to/file1.lua /path/to/file2.lua ...

    Embedded LUA Flash Store size. Set to zero to use an LFS partition instead
    of embedding the LFS within the NodeMCU firmware itself.

      Include support for accessing FAT filesystems on SD cards.
