Implementing the ADPCM algorithm in high-density STM32F103xx microcontrollers

Posted: 14 May 2009 ?? ?Print Version ?Bookmark and Share

Keywords:ST application noteAN2931? firmware? microcontroller? ADPCM algorithm?

This application note describes the ADPCM audio firmware codec, and provides a demonstration firmware showing how to play ADPCM files using the high-density STM32F103xx I2S feature with an external DAC.

This application note is based on "AN2739: How to use the high-density STM32F103xx microcontroller to play audio files with an external I?S audio codec." The features linked to the SPI, I?S and the external DAC will be skipped here because they are already explained in AN2739. It is therefore highly recommended to refer to AN2739 to fully understand this application note.
