Hello guys i’m looking to enhance my ESP32 smart clock project by adding volume control via a rotary encoder. I plan to use the MAX98357A I2S DAC for audio playback and want to know the best approach to integrate a rotary encoder with the ESP32, specifically how to read the rotary encoder’s position and direction changes and apply the volume changes to theMAX98357A DAC’s output in real-time
I’d appreciate guidance on the most efficient way to implement this feature
Hi Daniel, How are you? I wanted to mention that I strongly advise against using the MAX98357A for your project. This chip has some unpredictable behavior, and you might experience popping or crackling noises, even if you add bypass capacitors on the input. If you’d like more details or need further assistance, feel free to create a thread, and I’ll be happy to help you with your project.
the best is the ES7148
I will watch the video and then decide thank you @medic4950
Thanks for the video once again after watching the video down to the part 2 , I think i will go with the PCM5102A I2S DAC for better audio quality and stability. I’ll read the rotary encoder’s position and direction to adjust the volume in real-time. From what I have see. , the integration with the PCM5102A should be straightforward.
Great, do you need help for the rotary encoder?
