VS1053b is an Ogg Vorbis/MP3/AAC/WMA/FLAC/WAVMIDI audio decoder as well as an PCM/IMA ADPCM/Ogg Vorbis encoder on a single chip. It contains a high-performance, proprietary low-power DSP processor core VS_DSP4, data memory, 16 KiB instruction RAM and 0.5+ KiB data RAM for user applications running simultaneously with any builtin decoder, serial control and input data interfaces, up to 8 general purpose I/O pins, an UART, as well as a high-quality variablesample-rate stereo ADC (mic, line, line + mic or 2line) and stereo DAC, followed by an earphone amplifier and a common voltage buffer.VS1053b receives its input bitstream through a serial input bus, which it listens to as a system slave. The input stream is decoded and passed through a digital volume control to an 18-bit oversampling, multi-bit, sigmadelta DAC. The decoding is controlled via a serial control bus. In addition to the basic decoding, it is possible to add application specific features, like DSP effects, to the user RAM memory.
LibDriver VS1053B is the full function driver of VS1053B launched by LibDriver. It provides functions of audio playing, audio recording, etc. LibDriver is MISRA compliant.
/src includes LibDriver VS1053B source files.
/interface includes LibDriver VS1053B SPI platform independent template.
/test includes LibDriver VS1053B driver test code and this code can test the chip necessary function simply.
/example includes LibDriver VS1053B sample code.
/doc includes LibDriver VS1053B offline document.
/datasheet includes VS1053B datasheet.
/project includes the common Linux and MCU development board sample code. All projects use the shell script to debug the driver and the detail instruction can be found in each project's README.md.
