sc_usb_audio Change Log
|
|
=======================
|
|
|
|
HEAD
|
|
----
|
|
- RESOLVED: Enumeration issue when MAX_MIX_COUNT > 0. Introduced in mixer optimisations
|
|
in 6.11.0
|
|
- RESOLVED: Potential build issue due to duplicate labels in inline asm in
|
|
set_interrupt_handler macro
|
|
- CHANGE: HID report descriptor defines added to shared user_hid.h
|
|
- CHANGE: Now uses module_adat_rx from sc_adat (local module_usb_audio_adat removed)
|
|
|
|
6.11.1
|
|
------
|
|
- ADDED: ADAT transmit functionality, including SMUX. See ADAT_TX and ADAT_TX_INDEX.
|
|
- RESOLVED: Build issue with CODEC_MASTER (xCore is I2S slave) enabled
|
|
- RESOLVED: Channel ordering issue in when TDM and CODEC_MASTER mode enabled
|
|
- RESOLVED: DFU fails when SPDIF_RX enabled due to clock block being shared between SPDIF
|
|
core and FlashLib
|
|
|
|
6.11.0
|
|
------
|
|
- ADDED: Basic TDM I2S functionality added. See I2S_CHANS_PER_FRAME and I2S_MODE_TDM
|
|
- CHANGE: Various optimisations in 'mixer' core to improve performance for higher
|
|
channel counts including the use of XC unsafe pointers instead of inline ASM
|
|
- CHANGE: Mixer mapping disabled when MAX_MIX_COUNT is 0 since this is wasted processing.
|
|
- CHANGE: Descriptor changes to allow for channel input/output channel count up to 32
|
|
(previous limit was 18)
|
|
|
|
6.10.0
|
|
------
|
|
- CHANGE: Endpoint management for iAP EA Native Transport now merged into buffer() core.
|
|
Previously was separate core (as added in 6.8.0).
|
|
- CHANGE: Minor optimisation to I2S port code for inputs from ADC
|
|
|
|
6.9.0
|
|
-----
|
|
- ADDED: ADAT S-MUX II functionality (i.e. 2 channels at 192kHz) - Previously only S-MUX
|
|
supported (4 channels at 96kHz).
|
|
- ADDED: Explicit build warnings if sample rate/depth & channel combination exceeds
|
|
available USB bus bandwidth.
|
|
- RESOLVED: (Major) Reinstated ADAT input functionality, including descriptors and clock
|
|
generation/control and stream configuration defines/tables.
|
|
- RESOLVED: (Major) S/PDIF/ADAT sample transfer code in audio() (from ClockGen()) moved to
|
|
aid timing.
|
|
- CHANGE: Modifying mix map now only affects specified mix, previous was applied to all
|
|
mixes. CS_XU_MIXSEL control selector now takes values 0 to MAX_MIX_COUNT + 1
|
|
(with 0 affecting all mixes).
|
|
- CHANGE: Channel c_dig_rx is no longer nullable, assists with timing due to removal of
|
|
null checks inserted by compiler.
|
|
- CHANGE: ADAT SMUX selection now based on device sample frequency rather than selected
|
|
stream format - Endpoint 0 now configures clockgen() on a sample-rate change
|
|
rather than stream start.
|
|
|
|
6.8.0
|
|
-----
|
|
- ADDED: Evaluation support for iAP EA Native Transport endpoints
|
|
- RESOLVED: (Minor) Reverted change in 6.5.1 release where sample rate listing in Audio Class
|
|
1.0 descriptors was trimmed (previously 4 rates were always reported). This change
|
|
appears to highlight a Windows (only) enumeration issue with the Input & Output
|
|
configs
|
|
- RESOLVED: (Major) Mixer functionality re-instated, including descriptors and various required
|
|
updates compatibility with 13 tools
|
|
- RESOLVED: (Major) Endpoint 0 was requesting an out of bounds channel whilst requesting level data
|
|
- RESOLVED: (Major) Fast mix code not operates correctly in 13 tools, assembler inserting long jmp
|
|
instructions
|
|
- RESOLVED: (Minor) LED level meter code now compatible with 13 tools (shared mem access)
|
|
- RESOLVED (Minor) Ordering of level data from the device now matches channel ordering into
|
|
mixer (previously the device input data and the stream from host were swapped)
|
|
- CHANGE: Level meter buffer naming now resemble functionality
|
