Problems solved by technology
For example, BMW's CD is customized by BMW, and Audi's CD is customized by Audi, so although both are MOST devices, the CD devices of the two cannot be mixed
[0004] On the other hand, general audio input and output devices cannot be used in the MOST network, that is, they cannot upload their own audio to the MOST network, nor can they obtain audio from the MOST network, which requires special design

The present invention relates to an MOST network based universal car audio development platform includes an MOST network module, an MCU module, a display module, an audio input and output module, an interface module, and a keyboard input module. The interface module includes an MOST control module connected with the MCU module in an I2C mode. The audio input and output module connects an MOST controller, and the display module electrically connects the MCU module. The MOST controller is provided with a functional block for realizing audio input / output. The present invention also relates to an audio input and output method based on the platform. The MOST network based universal car audio development platform is compatible with most car types having the MOST network, and meets various decoding requirements by keyboard configuration and I2S signal format automatic identification. The MOST network based universal car audio development platform is high in intelligent degree, is reliable and universal, and is convenient for developers to operate. The MOST network based universal car audio development platform reduces the development cost for mounting MOST equipment, and shortens the development period of MOST audio equipment.
Description
technical field [0001] The invention relates to the field of vehicle audio input and output, in particular to a general-purpose vehicle audio development platform and a signal transmission method based on the MOST network. Background technique [0002] MOST (Media Oriented Systems Transport, media-oriented network transmission), as a bus technology for transmitting media information, provides a complete set of audio and video transmission solutions for vehicle manufacturers. Major car manufacturers (such as BMW, Mercedes-Benz, Audi, etc.) have designed their own MOST entertainment information transmission network according to the application requirements and in accordance with the MOST protocol specification. Due to the custom expansion of the MOST application protocol and the adoption of the differentiated I2S audio format by the automakers, most of the MOST devices on the market are not compatible with different car models. [0003] In the MOST protocol, one part is commo...
