ESP8266 is a highly integrated chip designed for the needs of a new connected world.It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.The ESP8266 support four different SPI flash access modes: DIO, DOUT, QIO & QOUT. These can be set via the --flash_mode option of esptool.py write_flash. More information about it,refer to: //github.com/espressif/esptool/wiki/SPI-Flash-Modes.

Description:Instruction & Steps of How to use:1. Download for Arduino IDE, the latest version.2. Install the IDE3. Set up your for Arduino IDE as: Go to File->Preferences and copy the URL below to get the ESP board manager extensions: http://for arduino.esp8266.com/stable/package_esp8266com_index.json Placing the http:// before the URL lets for Arduino IDE use it...otherwise it gives you a protocol error.4. Go to Tools > Board > Board Manager> Type "esp8266" and download the Community esp8266 and install.5. Set up your chip as:Tools -> Board -> NodeMCU 1.0 (ESP-12E Module)Tools -> Flash Size -> 4M (3M SPIFFS)Tools -> CPU Frequency -> 80 MhzTools -> Upload Speed -> 921600Tools-->Port--> (whatever it is)6. Download and run the 32 bit flasher exe at Github(Search for nodemcu/nodemcu-flasher/tree/master/ at Github) github.com/nodemcu/nodemcu-flasher/tree/master/Win32/Release Or download and run the 64 bit flasher exe at: github.com/nodemcu/nodemcu-flasher/tree/master/Win64/Release7. For Arduino IDE, look for the old fashioned Blink program. Load, compile and upload.8. Go to FILE> EXAMPLES> ESP8266> BLINK, it will start blinking.
