3.7 Using the I
2
C Memory Tool
The GUI installation includes an I
2
C 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 21 ), 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 I
2
C file needs to be loaded to update
device registers or when performing I
2
C debug.
Figure 21 shows a snap-shot of the Memory Tool window. Click the I
2
C tab at the top to view the
Read/Write and Execute I2C Command File options. For Read operation, provide register sub-address
and register size (length) in bytes. Clicking on the Read button displays the contents of the register in the
Data window. For a Write operation, provide the data to be written in the Data field, and then click the
Write button.
The Memory Tool can also be used to load a pre-defined I
2
C register file. Clicking the browse button on
the bottom-right allows the user to browse to the location of the I
2
C script file, after selecting the desired
file, clicking the Execute button, implements the register write operations specified in the file.
