//ESP8266-01 (blue) got too little storage space to work with all features of WLED. 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. Will also be disabled with OTA lock

//to toggle usb serial debug (un)comment the following line
