SGTL5000 ESP32

[Josh23]

Hey. I'm need some help. I am using the sgtl5000 to send data to the Esp32 via I2S from Line in. However I'm finding that the samples are repeated twice or thrice when I read them. I have given both the Esp32 and the SGTL5000 the same sampling frequency. I don't know what I'm missing

I truly appreciate you openly sharing your technical situation with the SGTL5000 and ESP32 over I2S, as it allows many others to learn from the repeated-sample issue. This instantly reminds me of Geometry Dash, where precision in each move is the key to overcoming obstacles. If you’re looking to solve it thoroughly, proactively review your clock settings and consult the official documentation of both devices to make proper adjustments.

Hello,

You ESP32 is acting like ping pong on the I2S bus please check it

You were right. The problem was with the I2S format. I was using the I2S standard format on the SGTL5000 but standard MSB on the ESP32. When I changed the ESP32 to use the I2S Phillips stanard format, it worked. Though I do get alot of noise on the signal when I reconstruct it at the esp32.

Ok. Let me investigate it.
