V2.0.0 / 18-February-2014
Main
Changes
- Major update
based on STM32Cube specification: drivers architecture and APIs
modified vs. V1.1.2, and thus the 2 versions are not compatible.
- This version has to be used only with STM32CubeF4 based development
V1.1.2 / 17-April-2012Main

V1.1.0 / 28-October-2011
Main
Changes
- Add PDM audio software decoding Library drivers, used to decode and reconstruct the audio signal produced by MP45DT02 MEMS microphone from STMicroelectronics. For more details about this Library, please refer to document "PDM audio software decoding on STM32 microcontrollers (AN3998)".
- stm32f4_discovery_audio_codec.c/.h: update to use DMA instead of Interrupt in I2S communication with the external codec.
