3.6 Using the Mixer and Scaler Nodes
Figure 19 below shows a snap-shot of the different mixer and scaler blocks from the GUI. The mixer
nodes can be used to mix the contents of the different channels. The input mixer can be used to mix the
channels before they are processed by the Bi-Quads and DRC, while the output mixer nodes are used to
mix the channels after they are processed through these blocks. The scaler blocks at the output can be
used to scale the outputs.
Clicking on any of these blocks displays their configuration option’s in the properties window. Figure 19
shows an example where the output-mixer 0x51 is selected. The mixer configuration can be updated by
changing the values in the properties window.

3.7 Using I2C Memory Tool
The GUI installation includes an I2C read-write interface, ‘called the Memory Tool’. Using the Memory tool,
the device registers can manually be read or written to. The tool can either be opened using the GUI
menu (as shown in
Figure 20 ), or can also be launched stand-alone even when the GUI window is not
opened, through the Windows → All-Programs → Texas Instruments Inc → I2C Memory tool option. The
stand-alone capability is especially convenient when an existing I2C file needs to loaded to update device
registers or when performing I2C debug.
Figure 20 shows a snap-shot of the Memory Tool window. The I2C tab at the top should be clicked to view
the Read/Write and I2C command file options. For Read operation, register sub-address and register size
(length) in bytes should be provided. Clicking on the Read button, displays the register’s contents in the
Data window. For a Write operation, the data to be written should be provided in the Data field, and then
the Write button should be clicked
The Memory tool can also be used to load a pre-defined I2C register file. Clicking the browse button on
the bottom-right allows the user to browse to the location of the I2C script file, after selecting the desired
file, clicking the Execute button, implements the register write operations specified in the file
