Hardware i2s pdm tx

[Jeronimo59]

Hello, and many thanks for this outstanding work !
I've found that ESP32 C3 & S3 now have Hardware i2s driver with a pdm mode.
https://docs.espressif.com/projects/esp-idf/en/v5.1/esp32/api-reference/peripherals/i2s.html
Are you considering to integrate this use case in your toolbox ?

Meanwhile, I am struggling with pdm tx in software, and didn't find any example (the only pdm example I found is for pdm RX).
Did I miss it ?

Thanks again,

Jérôme

It is already integrated, but I did not have the chance to test it yet. Just set the signal type in the I2S configuration and use the ESP32 v3.0.0 core

Any help will be appreciated.

Thanks for your prompt response.

I did not realize your implementation of PDM used ESP32 hardware driver already (I thought it was software-based).
I will test & get back to you.
