menu "NodeMCU platform config" config NODEMCU_NODE_DEBUG bool "Enable NODE_DBG() output" default "n" help Enable debugging output via NODE_DBG(). This is VERY chatty. For development/debugging use only. config NODEMCU_NODE_ERR 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 NODEMCU_DEFAULT_SPIFFS_LABEL string "Partition label of SPIFFS to mount as default file system" default "" help If there are multiple SPIFFS partitions, this setting can be used to control which partition gets mounted as the default file system. Leaving it empty defaults to using the first SPIFFS partition found. config NODEMCU_MAX_OPEN_FILES int "Maximum number of open files" default 4 help This sets the maximum number of open files at the same time. Technically, it's per file system, but the most common use case only has a single file system (internal SPIFFS) so in that case it is the number of concurrent files that can be opened. Raising this limit will incur some extra memory overhead. config NODEMCU_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 ... config NODEMCU_EMBEDDED_LFS_SIZE hex "Embedded LUA Flash Store size" default 0x0 depends on NODEMCU_EMBED_LFS help Embedded LUA Flash Store size. Set to zero to use an LFS partition instead of embedding the LFS within the NodeMCU firmware itself. menu "UART buffer size configuration" config NODEMCU_UART_AT_LEAST_2 bool default y if IDF_TARGET_ESP32 default y if IDF_TARGET_ESP32S2 default y if IDF_TARGET_ESP32S3 default y if IDF_TARGET_ESP32C3 default y if IDF_TARGET_ESP32H2 config NODEMCU_UART_AT_LEAST_3 bool default y if IDF_TARGET_ESP32 default y if IDF_TARGET_ESP32S3 config NODEMCU_UART_DRIVER_BUF_SIZE_RX0 int "RX buffer size for UART0" default 512 help The rx buffer size to use for UART0.
