ESP8266 Output GPIO and Optimization
Like many microcontrollers, the ESP8266 has a slew of GPIO pins that can be used to interact with the outside world. Espressif provides a number of ways to interact with these pins, including the popular function gpio_output_set. When we were … Continue reading

Configuring the Raspberry Pi as an ESP8266 Development Environment
The Raspberry Pi is an advantageous platform for developing ESP8266 software, as it can power the ESP with its 3.3V pins, communicate directly with the ESP via its serial GPIO pins, and natively runs the Xtensa cross-compiler on its Linux-based … Continue reading

ESP-12 Pin Overview
The ESP-12 has 16 pins broken out for the maker to use. A majority of them are simple GPIO pins, but others serve important dedicated purposes. These pins are: TXD & RXD: Communication pins used to send (TXD) and receive … Continue reading
