ESP32 & ESP8266- SPI serial communication, two boards
In this episode we are going to discuss third way of serial communication with ESP32 & ESP8266 microcontrollers. SPI is by far the most complicated one but, non the less, awesome technology. Here we are not going to describe technology itself but the way of how to use it to connect two boards. In this case, we are going to use esp32 and arduino uno.
