■The ESP8266EX offers a complete and self-contained Wi-Fi network solution. It can be used to host the applications or to offload Wi-Fi network functions from other application processors. When the ESP8266 hosts an application as the only processor in the device, it boots up directly from an external flash. It has an in-built, high-speed cache to improve the performance of the system and reduce the memory occupation. Alternately, when the ESP8266 is used as a Wi-Fi adapter, wireless internet access can be added to any micro controller-based device through the UART interface or the CPU AHB bridge interface, and thus provide the users with a simple Wi-Fi solution.
■ESP8266EX enjoys high level of on-chip integration. It integrates the antenna switch, RF balun, power amplifier, low noise receive amplifier, filters, and power management modules. It requires minimal external circuitry, and the entire solution, including the front-end module, is designed to occupy minimal PCB space.
■The ESP8266EX also integrates an enhanced version of the 32-bit processor of Tensilica’s L106 Diamond series, with on-chip SRAM. The ESP8266EX is often integrated with external sensors and other application specific devices through its GPIOs. The SDK files provide examples of the softwares of the related applications.
■The ESP8266EX system has many cutting-edge advantages, including energy-efficient VoIP that can switch rapidly between sleep and wake modes, adaptive radio bias for low-power operations, front-end signal processing capacity, problem-shooting capacity, and the radio system co-existence feature to remove cellular, bluetooth, DDR, LVDS and LCD interference.
■The SDK based on the ESP8266 IoT platform offers users a simple, high-speed and efficient software platform for IoT device development. This programming guide provides an overview of the SDK as well as details of the APIs. The target readers are embedded software developers who use the ESP8266 IoT platform for software development.
