To use it, you must use ESP8266 Arduino Core v2.4.2 and the setting 512K(No SPIFFS). //ESP8266-01 (black) has 1MB flash and can thus fit the whole program. Use 1M(64K SPIFFS). //Uncomment some of the following lines to disable features to compile for ESP8266-01 (max flash size 434kB): //You are required to disable over-the-air updates: //#define WLED_DISABLE_OTA //saves 14kb //You need to choose some of these features to disable: //#define WLED_DISABLE_ALEXA //saves 11kb //#define WLED_DISABLE_BLYNK //saves 6kb //#define WLED_DISABLE_CRONIXIE //saves 3kb //#define WLED_DISABLE_HUESYNC //saves 4kb //#define WLED_DISABLE_INFRARED //there is no pin left for this on ESP8266-01, saves 12kb #define WLED_ENABLE_MQTT //saves 12kb #define WLED_ENABLE_ADALIGHT //saves 500b only //#define WLED_ENABLE_DMX //uses 3.5kb #define WLED_DISABLE_FILESYSTEM //SPIFFS is not used by any WLED feature yet //#define WLED_ENABLE_FS_SERVING //Enable sending html file from SPIFFS before serving progmem version //#define WLED_ENABLE_FS_EDITOR //enable /edit page for editing SPIFFS content.
