ESP8266

General Purpose Input/Output Interface (GPIO) ESP8266EX has 17 GPIO pins which can be assigned to various functions by programming the appropriate registers.Each GPIO can be configured with internal pull-up or pull-down, or set to high impedance, and when configured as an input, the data are stored in software registers; the input can also be set to edge-trigger or level trigger CPU interrupts. In short, the IO pads are bidirectional,non-inverting and tristate, which includes input and output buffer with tristate control inputs.These pins can be multiplexed with other functions such as I2C, I2S, UART, PWM, IR Remote Control, etc. Secure Digital...
