sc_usb_audio Change Log
=======================
+6.18.1
+------
+ - ADDED: Vendor Specific control interface added to UAC1 descriptors to allow control of
+ XVSM params from Windows (via lib_usb)
+
+6.18.0
+------
+ - ADDED: Call to VendorRequests() and VendorRequests_Init() to Endpoint 0
+ - ADDED: VENDOR_REQUESTS_PARAMS define to allow for custom parameters to VendorRequest calls
+ - RESOLVED: FIR gain compensation set appropriately in lib_mic_array usage
+ - CHANGE: i_dsp interface renamed i_audManage
+
+6.16.0
+------
+ - ADDED: Call to UserBufferManagement()
+ - ADDED: PDM_MIC_INDEX in devicedefines.h and usage
+ - CHANGE: pdm_buffer() task now combinable
+ - CHANGE: Audio I/O task now takes i_dsp interface as a parameter
+ - CHANGE: Removed built-in support for A/U series internal ADC
+ - CHANGE: User PDM Microphone processing now uses an interface (previously function call)
+
6.15.2
------
- - RESOLVED: interrupt.h (used in audio buffering) now compatible with xCORE-200 ABI
+ - RESOLVED: interrupt.h (used in audio buffering) now compatible with xCORE-200 ABI
6.15.1
------
- - RESOLVED: DAC data mis-alignment issue in TDM slave mode
+ - RESOLVED: DAC data mis-alignment issue in TDM/I2S slave mode
- CHANGE: Updates to support API changes in lib_mic_array version 2.0
6.15.0
