Quick reference for the ESP32. The Espressif ESP32 Development Board (image attribution: Adafruit). Below is a quick reference for ESP32-based boards. If it is your first time working with this board it may be useful to get an overview of the microcontroller: General information about the ESP32 port.Both ESP8266 and ESP32 Arduino core implementation added a printf method to its Serial class, so that you can do call Serial.printf () like the way c printf () do. What this means is that ESP32 and ESP8266 supports floating point on Arduino out-of-box. The following code running on ESP32 and ESP8266 will provide the correct floating point results.Following on from the FTDI + ESP8266 post, if you do not have a FTDI serial adaptor you can use an Arduino. Here is how to set up the Arduino to talk to the ESP8266. I an using a 5V Arduino Nano which of course is 5V. The Esp8266 is a 3.3v device and so I am using a voltage divider to bring the Arduinos 5V down to 3.3v.To set up for debugging on Windows.
