Le Potato audio input?

[o_o]

Does the AML-S905X-CC have any avenue for analog audio input (recording)? I believe I understand the AV jack is an output only. GPIO? Or must I use an add on device such as a USB sound device? Thanks.

Le Potato has an audio header capable of I2S and PCM input. USB is recommended as it is easier unless you are looking for hi-fidelity or latency sensitive audio.

Good to hear, thanks.

I am looking for latency sensitive audio. USB is not viable. I have an i2s adc lying around which work well with RPi but Le Potato fits my project so much better. Unfortunately there is next to no information available. All I could find out was that I had to write a DT overlay to first enable i2s. Any pointers to that?

How to control GPIO via C or Python 3

I think perhaps it would be more helpful if you assumed that there is a strong likelihood that many readers have no knowledge whatsoever of Device Trees and Overlays. As you mention in various posts they are pretty essential for working with the Le Potato and the ldto tool mentioned in this post How to Enable SPI on AML-S905X-CC Le Potato - Hardware - Libre Computer Hub is an excellent tool for applying existing overlays. After a good few hours of internet research, I have learned enough to …

The I2S nodes are already in the device tree, you just need to enable them by changing the status flag.

I don’t see that the I2S nodes are in the device tree. I really want to use I2S, but the information is completely missing other than I did find the GPIO pin out.
