2 months ago Hi, we've several suggestions for your reference:
1）May use examples/camera from esp-iot-solution repo, to validate that the devboard and camera sensor are working fine. 2）DVP camera on esp32-eye is implemented with I2S0 as default, so if you're using I2S, better to avoid I2S0 when camera is enabled.
Have a nice day~

What is the expected behavior?
A function that measures the voice dB and captures the image when it exceeds a certain dB and outputs it to the web server
What is the actual behavior?
현재 i2s_channel_read 이 부분에서 제대로 작동하지 않아 버그가 발생하고 있습니다,
