 Introduction
 ------------
   The WiFi module ESP-F is manufactured by using a high-performance chip ESP8266EX, which can be seen in Fig. 1. This small chip is encapsulated an enhanced Tensilica’sL106  diamond series 32-bit kennel CPU with a SRAM. Thus, ESP8266 has the complete function Wi-Fi function; it not only can be applied independently, but can be used as a slaver working with other host CPU. When ESP8266 is applied as a slaver, it can start from the onboard Flash.  The built-in high-speed buffer is not only benefit to improve the system performance, but optimize the store system. In addition, ESP8266 can be used as Wi-Fi adapter by SPI/SDIO or I2C/UART interface, when it is applied to other MCU design.
