Esp32 dac audio example

ESP32-S2 has two 8-bit DAC (digital to analog converter) channels, connected to GPIO17 (Channel 1) and GPIO18 (Channel 2). The DAC driver allows these channels to be set to arbitrary voltages. The DAC channels can also be driven with DMA-style written sample data by the digital controller, however the driver does not supported this yet. I did not want to wait for the DAC device to arrive and fortunately we can also use the built in DAC of the ESP32 to generate the sound. Web Radio Software.
