The first in a series of videos explaining I2S and how to use with the ESP32. This opening episode keeps it very simple just using the included standard Espressiv libraries. There is a full explanation of how I2S is implemented followed by a run through of the demo software - which has been kept very simple.

A supporting web page is available with the demo code on at

If you'd like to support me via Patreon then the link is below and that would be just amazing. Patreons have access to all videos early plus can view all the posts on Patreon. There are other rewards if you're interested. If you just want to watch videos then that's also fantastic because without people viewing I wouldn't even do half of what I do. So thanks very much :)
