Web1. Introduction - ESP32 has two I2S peripherals. They can be configured to input and output sample data. They also supports DMA to stream sample data without needing CPU operations. I2S output can also be routed directly to the Digital to Analog Converter output (GPIO25 and GPIO26) without needing external I2S codec. - In this demo I will show you … Web-Assign a read function/task to the core0 to read the values from the DMA buffer. vi. The Inter-Integrated Circuit Sound Protocol, or I2S, was developed by Phillips Semiconductors in 1986. .
