USB - CODEC configuration editor v2.01 User Manual
3.3 Version 1.02, third release
- The mute function was set to active in all four topologies. We have disabled this function when the default
values are loaded and also provided user control for this function in address 09h.
- In address 0Fh the user seemed to have the choice to select a topology, while this combo-box was always
disabled. We have replaced the combo-box with a normal text-box to indicate that this is only for information and
not for selecting purposes.
- If we look to address 0Fh again, we see in the previous version of the editor that when the I²S – selection was
disabled, the user still could select the 4-pins or 6-pins configuration. This is not logical, so we disabled the 4-
pins and 6-pins options when the NO I²S - bus used is selected.
- The Time between mute an play address was settable to 0, which is not supported by the firmware. Lower-level
set to 1.
- When the user selects 0 for the Time between Mute and Standby, this will autom. tell the state-machine of the
firmware that this function is disabled. The user will be reminded to the status when he/she selects 0 by means of
a text-label.
- The range of the Default value for DBB is 24 dB not 255, as was implemented in the previous editor.
- Range limitation is also implemented for address 15h, where the Startup default volume setting is located.
The maximum settable value is –60 dB.
- The definitions of the output-polarity of the HID outputs in addr. 0Bh were inverse implemented. Corrected bug.
- The title of address 0Fh in the datasheet was changed into I²S and Topology selection. To stay tuned we
changed the title in the editor too.
- The PID number in the Device Descriptor field was not settable to any desired value, instead there were only a
few selectable via a combo-box. To be flexible and after customers request, we changed the control, in which the
user can set any value for PID, VID and bcdDevice.
- Address 2C8h had a typo. Instead of the value C0h it had the value CDh which caused the inability to select the
stereo / 8 bits recording option.
- When 0 dB was selected for the DBB value, it should change the descriptor bit regarding this function to 0,
indicating that this function is not used. This was not implemented in the previous version of this editor.
O.K. now.
- Topology 3 had some errors regarding discriptor length and faulty unit reference. Corrected this bug.
- When the user selects topology 3 or 4, this means that the descriptor wMaxPackageSize has to be recalculated
and filled in the respective interface (=2=recording), regarding the sample-frequency that is set in address 17h.
- Changing the divide factor in address 02h will also cause the wMaxPackageSize to be updated in the respective
descriptor fields.
- We have finally enabled the Save as command in the Save Config. menu. Hope that it will be usefull.
At the same time we have put extra safety measures for faulty file-names and warnings for overwriting existing
files.
- We have also put extra safety measures for situations when the editor is unable to locate the helpfile.
This situation occurs when the user has installed the program and runs the editor for the first time without the
use of the shortcut.
- In order to provide the most important information at one place, we have also provided a status bar at the main-
screen of the editor.
