  • I²S (Inter-IC Sound), pronounced eye-squared-ess, is an electrical serial bus interface standard used for connecting digital audio devices together. It is used to communicate PCM audio data between integrated circuits in an electronic device. The I²S bus separates clock and serial data signals, resulting in simpler receivers than those required for asynchronous communications systems that ...

  • The audio samples are just instantaneous voltage values. If you reduce the values, you reduce the voltage variation, and hence also reduce the volume. But the I2S controller won't do that for you. As far as the duration of the tone, the I2S controller can keep playing the same sample buffer over and over until you turn off the transmit function.

I2S (not to be confused with I2C) in a digital sound protocol that is used on circuit boards to pass audio data around. Many high end chips and processors manage all of the audio in digital I2S format. Then, to input or output data, three or four pins are used (data in, data out, bit clock and left-right channel select).

I did that on a zc702 board to test with a logic analyser, now the signals are routed to a DAC on a custom board and work fine. So pretty much any eval board will be fine, you just need three or four spare general purpose outputs - GPIO headers, PMOD connectors etc. will all be fine as long as the bank voltage is ok for your I2S sink device.
