Understanding the I²S Audio Protocol in Embedded Systems

Описание: Digital audio transmission in embedded systems often relies on I²S (Inter-IC Sound), a serial bus interface developed by Philips for seamless digital audio communication between ICs — such as microcontrollers, DSPs, and audio codecs.
Unlike general serial interfaces like SPI or UART, I²S is synchronized for continuous audio data streaming, ensuring precise timing and phase alignment between channels.
