WebDec 9, 2024 · As we have already mentioned that ESP WROOM-32 has 16 PWM channels (0 to 15). So, the first step will be to select a PWM channel between 0-15. In the Arduino IDE code, we are using PWM channel_0 to generate a PWM signal. The next step will be to choose the resolution. The maximum resolution for ESP32 is 16-bit. WebMar 19, 2024 · Phase Alternate Line helps a lot here. NTSC is a lot more fussy about phase stability, jitter and frequency of its color carrier. DAC + DDS at 13.33Mhz produces a beautiful looking waveform but very sketchy color if any on most TVs. Turns out the ESP32 has a great tool for creating rock solid color carriers: The Audio Phase Locked Loop.
