Esp32 waveform generator

WebHere, I will explain the foundation of the project to build an SPWM generator using ESP32. A. Definition of SPWM (Sinusoidal Pulse Width Modulation) is a modulation technique used to modulate the amplitude of a sinusoidal wave by changing the pulse width of a high-frequency wave. WebThe frequency of the internal cosine waveform (CW) generator is easily set but somehow limited in range and stepsize. However, for simple requirements using the internal CW generator instead of external DAC hardware might save you time & costs. According to ESP32 technical specs the CW frequency fcw is calculated as follows:
