What is ESP8266 GPIO and Usage Guide about?

The ESP8266 has 17 GPIO pins but only 11 can be used as general purpose I/O pins. It has one analog input, two UARTs, and hardware support for I2C, SPI and software PWM. Programming the ESP8266 is very similar to an Arduino with digital I/O, analogRead, Serial, I2C and SPI using the same syntax. The ESP8266 needs to yield CPU time periodically to the WiFi and TCP/IP stacks to avoid crashes or lost data due to slow program loops.
