In Chapter 16 (Signal generation), an ESP8266 or ESP32 microcontroller generated square wave signals with variable duty cycle or generated sine and triangular wave signals when combined with an AD9833 waveform generator module. Sine waves were also generated with the addition of an external DAC (digital to analog converter) MCP4725 module to the ESP8266 microcontroller or with the built-in DAC of the ESP32 microcontroller. In Chapter 5 (MP3 player), a microcontroller ...
