[lhartmann] takes these 32 bits and feeds them into four shift registers, producing 32 outputs from just the four I2S data lines. That’s more than enough signals to run the stepper motors.

Inspiration was then taken from a project by [Sprite_tm], which used the I2S peripheral to drive a small LED display without placing load on the CPU. Using the ESP32’s I2S peripheral in parallel ...

The Arasan I2S Controller IP Core is a two-channel I2S serial audio controller compliant to the Philips* Inter-IC Sound specification. The I2S bus is used for connecting audio components such as ...

The transceiver can act as a controller (master) or a target (slave) for Inter-IC Sound (I2S) and Time-Division Multiplexed (TDM) audio interfaces, exchanging mul-ti-channel audio samples over a ...
