#ifndef __USER_CONFIG_H__ #define __USER_CONFIG_H__ // The firmware supports a range of Flash sizes, though 4 Mbyte seems to be // the most common currently. NodeMCU builds include a discovery function // which is enabled by FLASH_AUTOSIZE, but you can override this by commenting // this out and enabling the explicitly size, e.g. FLASH_4M. Valid sizes are // FLASH_512K, FLASH_1M, FLASH_2M, FLASH_4M, FLASH_8M, FLASH_16M. #define FLASH_AUTOSIZE //#define FLASH_4M // The firmware now selects a baudrate of 115,200 by default, but the driver // also includes automatic baud rate detection at start-up. If you want to change // the default rate then vaild rates are 300, 600, 1200, 2400, 4800, 9600, 19200, // 31250, 38400, 57600, 74880, 115200, 230400, 256000, 460800 [, 921600, 1843200, // 368640]. Note that the last 3 rates are not recommended as these might be // unreliable, but 460800 seems to work well for most USB-serial devices. #define BIT_RATE_DEFAULT BIT_RATE_115200 //#define BIT_RATE_AUTOBAUD // Three separate build variants are now supported. The main difference is in the // processing of numeric data types. If LUA_NUMBER_INTEGRAL is defined, then // all numeric calculations are done in integer, with divide being an integer // operations, and decimal fraction constants are illegal. Otherwise all // numeric operations use floating point, though they are exact for integer // expressions < 2^53. // The main advantage of INTEGRAL builds is that the basic internal storage unit, // the TValue, is 8 bytes long. We have now reduced the size of FP TValues to // 12 bytes rather than the previous 16 as this gives a material RAM saving with // no performance loss. However, you can define LUA_DWORD_ALIGNED_TVALUES and // this will force 16 byte TValues on FP builds. //#define LUA_NUMBER_INTEGRAL //#define LUA_DWORD_ALIGNED_TVALUES // The Lua Flash Store (LFS) allows you to store Lua code in Flash memory and // the Lua VMS will execute this code directly from flash without needing any // RAM overhead.

This can be any multiple of 4kB up to // a maximum 256Kb. //#define LUA_FLASH_STORE 0x10000 // By default Lua executes the file init.lua at start up. The following // define allows you to replace this with an alternative startup.

The latter requires extra H/W so is less common. // If you use SPIFFS then there are a number of options which impact the // RAM overhead and performance of the file system. // If you use the spiffsimg tool to create your own FS images on your dev PC // then we recommend that you fix the location and size of the FS, allowing // some headroom for rebuilding flash images and LFS. As an alternative to // fixing the size of the FS, you can force the SPIFFS file system to end on // the next 1Mb boundary. This is useful for certain OTA scenarios. In // general, limiting the size of the FS only to what your application needs // gives the fastest start-up and imaging times. #define BUILD_SPIFFS //#define SPIFFS_FIXED_LOCATION 0x100000 //#define SPIFFS_MAX_FILESYSTEM_SIZE 0x20000 //#define SPIFFS_SIZE_1M_BOUNDARY #define SPIFFS_CACHE 1 // Enable if you use you SPIFFS in R/W mode #define SPIFFS_MAX_OPEN_FILES 4 // maximum number of open files for SPIFFS #define FS_OBJ_NAME_LEN 31 // maximum length of a filename //#define BUILD_FATFS // The HTTPS stack requires client SSL to be enabled.
