The "Get Software" button will start the driver download It will download a file name slac435c.zip. Before you can go any further you will need to download and install the driver software.
MSP430 Launchpad uses proprietary USB drivers, so when you first plug it in, Windows won't be able to automatically initialize the device. I've tested the DRO firmware with Launchpad versions 1.3, 1.4 and 1.5 and they all work equally well.
If you already purchased a kit and it came with the wrong chip you can order the correct IC from TI.com, Mouser or any other component supplier. On the other hand, many sellers on Amazon and are still selling old V1.3 stock with 16-pin MCU. At the time of this writing Launchpads purchased directly from TI's store use PCB version 1.5 and ship with MSP430G2553 microcontroller. To save yourself a lot of frustration later, please verify that you got the right version of the Launchpad with the correct chip installed. Brian Dantz has left a detailed comment (down below) that outlines the changes. 2, 2015: It appears that TI moved some things around their website. Instead the pre-compiled firmware can be flashed using a free command line MSP430 Flasher tool offered by Texas Instruments. Fortunately, you don't need to install the full-blown IDE, list TI Code Composer Studio or even the MSPGCC tool chain. On the other hand, firmware upload process is not as user-friendly as that offered by the Arduino software.
Compared to the original version that used Arduino, the Launchpad version has a few advantages, such as lower cost and simpler construction. A few months ago I posted build instructions for a DRO controller that uses MSP430G2553 microcontroller with a TI MSP430 Value Line Launchpad.
