How to create an I2S interface with a slave AXI stream interface. The audio codec implemented on the STM32L152D-EVAL is the CS43L22 from Cirrus Logic ®. The I2S standard was introduced by Philips Semiconductors (now NXP) in 1986 and was revised in 1996. I2S/PCM Audio DAC with Headphone and Mono Class-D Speaker Amplifier. As you can see in the AudioBit pinout, a typical codec will have an I2S bus for audio data and I2C bus for control inputs such as setting I2S data format or configuring the mixing of sound tracks, audio volume… and a LOT of things. 17 36In Stock The two I2S/PCM interfaces support all common sample rates between 8 to 96kHz in master and slave modes. Codec i2s interface I2S (Inter-IC Sound) is a serial, synchronous communication protocol that is usually used for transmitting audio data between two digital audio devices.
