17、ailable BoosterPack plug-in modules. You can quickly add features like wireless, displays, sensors, and much more. You can either design your own BoosterPack or choose among many already available from TI and elsewhere. The 40-pin interface is compatible with any 20-pin BoosterPack that is compliant
18、 with the standard (see Section 2.7 for details).The MSP430F5529 16-bit MCU has 128KB flash, 8KB RAM, 25-MHz CPU speed, integrated USB, and many peripherals plenty to get you started in your development.Custom USB functionality can be quickly added, using the free open-source USB tools and examples
19、available in the MSP430 USB Developers Package. This includes the MSP430 USB Descriptor Tool, which quickly customizes any combination of USB interfaces and automatically generates your USB descriptors for those interfaces.Free software development tools are also available - TIs Eclipse-based Code C

27、), mspgcc, or Energia open-source platform. See Section 3.2 for help choosing a platform.The out-of-box demo works without this step, but the host reports that the integrated eZ-FET lite emulator did not enumerate.(Be aware that the USB API does not yet fully support mspgcc development, but mspgcc d
28、oes contain the eZ-FET drivers.)Step 2: Connect the HardwareConnect the LaunchPad to a host PC using the USB cable included with the LaunchPad. The demo should work on any recent version of these operating systems. If prompted, let the PC automatically install software. The install is silent, which
29、means that the PCs operating system already has the drivers it needs.When you connect a USB device to your computer, the computer goes through the enumeration process. During enumeration, the host asks for the devices USB descriptors to learn the devices identity, capabilities, and more. Using the d
30、escriptors, the device presents one or more USB interfaces to the host, where each interface is associated with either a pre-defined device class, or a custom driver. The major operating systems already ship with drivers for most common device classes, which is why you do not need to provide them du

32、hese classes.Note: The eZ-FET emulator, application UART, and USB hub also enumerate when the LaunchPad is attached. These are part of the LaunchPad emulator, and so they always enumerate on Windows and Linux PCs, no matter what software is loaded into the MSP430F5529 device. In contrast, the MSC an
33、d HID interfaces described in this section are generated by the software demo application that is loaded onto the LaunchPad as shipped from TI. See Section 2.2.3 for more information.Step 3: Verify the storage volume has been loadedWhen you attach the LaunchPad to the PC, a storage volume is mounted
