Hi Gang

Noob here. I'm trying to run the sample Mozzi Sinewave sketch and, while it runs perfectly in the Arduino IDE, it won't compile in VS Code. The missing file is r_i2s_api.h.

Any ideas where I could find this file (and maybe its companion .cpp)?

Many thanks.

Hi!

Mozzi is meant to be used in the Arduino IDE, this is where all the development is taking place, so there is no guarantee that I works in VS… What board are you using? It seems like VS is missing some library for the I2S of your board.
