installed already with the IDE installation. If for any reason the Install Wizard starts, respond to
the prompts and point the wizard to the driver files which are located (on a default installation) in
directory:
CCS: C:\Program Files\Texas Instruments\MSP430_USB_DRIVERS_v3\USB
IAR: C:\ProgramFiles\IAR Systems\Embedded Workbench x.x\430\drivers\TIUSBFET\WinXP
The MSP430 Hardware Tool User’s Guide (Appendix F) gives detailed instructions how to install
the USB drivers. A link to this document can be found in www.msp430.com under the User’s
Guides tab.
3. Use the 14-conductor (JTAG) cable to connect the evaluation module to a FET programmer (14-
conductor cables are supplied with the FET programmers - parallel PC-FET (MSP-FET430Pxxx)
and USB-FET (MSP-FET430Uxxx)). Ensure that the JTAG cable is plugged in correctly and that
all jumpers (LEDs, and Vcc) are in place.
4. The evaluation module is now ready to be used for programming and debugging the MSP430.

(MSPFET430UIF)
•USB Connector: The USB type B connector on the target board is used to connect the USB
cable (Type A to B) between PC and the target board
4.3.2 Jumper Settings
The default jumper settings of the target board are:
1. JP3 set to internal (FET powered)
2. JP2 closed (LED)
3. JP4 open (not USB powered)

Getting Started 5
This section discusses about the two power scenarios (MSP-FET430UIF powered and USB
powered) and the correct jumper settings required in both the cases.
• USB Powered Scenario (default jumper setting): Connect pin 3-2 of JP3 to indicate to the
MSP-FET430UIF that external on-board power is used. Close jumper JP4 connection in order to
use the USB bus power.
NOTE: The USB connection from the MSP430 target board to the PC can only be used for
powering the device (if bus powered configuration is set) and for USB transmissions to and from
the MSP430.
To open a debug session via the IDE, the MSP-FET430UIF is required.
• USB FET Powered Scenario: Place jumper on pins 1-2 of JP3 to use the internal USB FET
power and make sure pin header JP4 is not closed. Pin Header JP1 is closed in both the power
scenarios cases. This jumper can be removed to measure board current.
4.4 Setting up a USB Code Example
Detailed information on the MSP430 USB offering is available in the document Starting a USB
Design Using MSP430 MCUs. The section below outlines getting started with development on
the F6638 using a USB code example.
4.4.1 Attach the USB-FET Tool to the PC
Connect the USB-FET tool to a spare USB port on the PC using the USB cable.
If the USB-FET tool (MSP-FET430UIF) is attached to the PC for the first time, the device must
be installed as described in section 4.2.
4.4.2 MSP430F6638 Target Board Connections
•Place the XMSP430F6638 unit in the device socket that is present on the MSP-TS430PZ100
USB Target board
•To ensure the jumper settings on the target board are correct (default jumper settings) refer to
section 4.3.2 of this document
•Connect the 14 pin conductor cable between the JTAG connector on the target board and the
MSP-FET430UIF FET tool.
•Make sure the USB cable (Type A to B) is used to connect the Type B USB connector on the
target board and a spare USB port on the PC.
4.4.3 USB Firmware for the F6638
The USB Communications Device Class (CDC) API firmware can serve as the foundation of a
USB application on the MSP430. The CDC is a device class supported by the USB
Implementers’ Forum, as well as all major OSes, which causes a “virtual” COM port to be
mounted on the PC. The COM port can then be accessed by various PC applications. One such

6Getting Started
PC application is the HyperTerminal, which is installed as part of a Windows and is therefore
available on any Windows-based PC.
The USB API stacks and all the demo example codes/applications that use the USB CDC API
can be downloaded from the MSP430F6638 product folder online, under the Tools & Software
section. For detailed information regarding the USB stacks, refer to the documents MSP430
USB CDC API Examples.pdf that is located within the zip file.
4.4.4 Using CCS/IAR to Compile/Download/Run the Firmware
If the default power jumper settings are used: make sure the USB cable is connected between
the Type B connector on the target board and a spare serial port on the PC.
First download the “MSP430 USB CDC+HID API Stacks” present in the MSP430F6638 online
product folder under the Tools & Software section to a known location on the PC.
The following steps help compile and debug the API firmware in both CCS and IAR development
platforms:

first time with the firmware running, device installation/first time enumeration occurs.
Refer Section 4.6
4.5 USB Device First-Time Enumeration
When a USB device is attached to a USB host (PC), the host enumerates it; that is, it queries
the device as to what it is, and loads the corresponding drivers. The first time a device is
attached, the OS may need help in locating the corresponding drivers so it can install the new
device. Windows requests this by prompting the “Found New Hardware” wizard.
Drivers for CDC (Communications Device Class) are already installed within Windows, but
Windows needs to be guided to an *.inf file (MSP430_CDC.inf) included with this kit. Using this
*.inf file, Windows can finish loading the appropriate drivers.
NOTE: The enumeration procedure discussed here, takes place only the first time a specific
USB device is connected to the USB host (PC). Successive enumerations for the same USB
device happen without any need for user intervention.
The following steps give a detailed description of the device installation/first-time enumeration
procedure for MSP430F6638 (under Windows XP). The procedures are also somewhat similar
for other Windows operating systems.
1. On connecting the MSP430F6638 target board to PC, Windows detects the new device
attached to PC and initiates the “Found New Hardware Wizard” prompting the user to
install the software for the detected USB Device.
2. Select "No, not this time" from the options available and then click "Next" to proceed with
the installation.

3. Select "Install from a list or specific location (Advanced)" as shown below and then click
"Next".
4. In the “Choose your search and installation options” window, select “Search for best
driver in these locations” options and use the browse button to enter the file path that
contains the USB API firmware in the combo-box. The *.inf file (MSP430_CDC.inf) is
stored in the following folder location:
