Storage Volume, Mounted From The Msc Interface; Files On The Storage Volume - Texas Instruments LaunchPad MSP-EXP430F5529LP User Manual

Getting Started
Figure 3. Storage Volume, Mounted from the MSC Interface
This storage volume is stored within the MSP430F5529's on-chip flash. It is small compared to most flash
drives, but it is large enough for the demo's needs. The MSP430 software presents it to the host through
the MSC interface.
If you open the volume, you see these files:
Table 1 describes the function of these files.
File
Button1.txt
Button2.txt
MSP430 USB
LaunchPad.url
README.txt
If you place other files inside the volume, they are stored inside MSP430 flash. But keep in mind that the
volume is only approximately 60KB in size. If you later download the software demo (or any software) to
the F5529 target, any data that you have placed in the volume will be lost.
If you change the name of the Button1.txt or Button2.txt file, the pushbutton functionality no longer works.
This is because the MSP430 demo software looks for these files by name.
Step 4: Open a text editor, and press the buttons
In addition to the MSC interface, the other USB interface that is enumerated by the demo is an HID
interface, which is used to emulate a keyboard. When you press the S1 or S2 button, the text stored in the
Button1.txt or Button2.txt file, respectively, is sent to your computer as typed keystrokes.
