Peripheral AudioEdit
The Audio interface available on AXEL Lite is based on i.MX6 SoC which provides the following subsystems characteristics:
- Audio codecs are provided by SW, which runs on ARM core, supporting (but not limited to) MP3, WMA, AAC, HE-AAC and Pro10
- 3x SSIs
- ESAI (Enhanced Serial Audio Interface)
- SPDIF Tx/Rx
- Audmux
- Audio sample rate conversion accelerator (ASRC)
DescriptionEdit
The i.MX6 processor provides SSI Synchronous Serial Interface port that allow to communicate with audio codecs that implement the inter-IC sound busstandard (I2S).
The SSI has independent transmitter and receiver sections with independent clock generation and frame synchronization.
The processor also provides standard Sony/Philips Digital Interface (SPDIF) stereo transceiver that allows the processor to receive and transmit digital audio.
Pin mappingEdit
The Pin mapping is described in the Pinout table section
