Module W8782 ADC I2S STEREO with Raspberry Pico

[Gustavomurta]

I'm committed to experimenting with this very interesting module. My intention is to connect it to the Raspberry Pico and capture stereo audio with excellent quality. Since I'm not experienced in programming (Tinygo), it will be another challenge.

The module is Chinese and I couldn't find any documentation for it.That's why I developed the electronic circuit schematic so I could understand how to use it. I did some tests without the Raspberry Pico and I think it's very promising!

Hi @Gustavomurta take a look at the code here for an example on how to get started with I2S on the rp2040: https://github.com/tinygo-org/pio/blob/main/rp2-pio/examples/i2s/main.go

Thank you, deadprogram!

Hi deadprogram,
In 2023, I tested with Tinygo I2S to DAC converter PCM5102A and it worked perfectly. Only now the direction of the data is the other way around. The Audio will be converted by the ADC and the data will be sent through the I2S interface, to the Raspberry Pico.
