Features specific to the ESP32 microcontroller are described in this chapter. In Chapter
21 (Microcontrollers), differences in instructions for ESP8266 and ESP32 microcontrollers regarding features that are available to both microcontrollers were described. The ESP32 microcontroller has two cores, which are managed independently, Bluetooth communication and Bluetooth Low Energy (BLE) communication, four independent timers, a digital to analog converter (DAC) with capacitive touch sensors, and a Hall effect sensor. The ESP32 DEVKIT DOIT development board is illustrated ...
