Getting Started www.ti.com 1 Getting Started 1.1 Introduction The MSP-EXP430FR6989 LaunchPad Development Kit is an easy-to-use Evaluation Module (EVM) for the MSP40FR6989 microcontroller (MCU). It contains everything needed to start developing on the ultralow-power MSP430FRx FRAM microcontroller platform, including on-board emulation for programming, debugging and energy measurements.
Getting Started 1.4 www.ti.com First Steps: Out-of-Box Experience An easy way to get familiar with the EVM is by using its preprogrammed out-of-box code. This code demonstrates some key features from a user level. 1.4.1 Connecting to the Computer Connect the LaunchPad using the included USB cable to a computer. A green power LED should illuminate. For proper operation, drivers are needed. TI recommends installing these driver by installing an IDE such as TI's CCS or IAR EW430.

Hardware 2.2.2 www.ti.com eZ-FET Onboard Emulator With EnergyTrace™ Technology To keep development easy and cost effective, TI's LaunchPad Development Kits integrate an onboard emulator, which eliminates the need for expensive programmers. The MSP-EXP430FR6989 has the eZFET emulator (see Figure 5), which is a simple and low-cost debugger that supports all MSP430 device derivatives. Figure 5. eZ-FET Emulator The MSP-EXP430FR6989 LaunchPad features full EnergyTrace++ technology.
Hardware www.ti.com 2.2.3 Emulator Connection: Isolation Jumper Block The isolation jumper block at jumper J101 connects or disconnects signals that cross from the eZ-FET domain into the MSP430FR6989 target domain. This includes eZ-FET Spy-Bi-Wire signals, application UART signals, and 3.3-V and 5-V power (see Table 2 and Figure 6).

Hardware www.ti.com Figure 7. Application Backchannel UART in Device Manager The backchannel UART is the "MSP Application UART1" port. In this case, Figure 7 shows COM13, but this port can vary from one host PC to the next. After you identify the correct COM port, configure it in your host application according to its documentation. You can then open the port and begin communication to it from the host. On the target MSP430FR6989 side, the backchannel is connected to the eUSCI_A1 module.

Hardware 2.3 www.ti.com Power The board was designed to accommodate various powering methods, including through the on-board eZFET as well as external or BoosterPack power. Figure 9. MSP-EXP430FR6989 Power Block Diagram 2.3.1 eZ-FET USB Power The most common power-supply scenario is from USB through the eZ-FET debugger. This provides 5-V power from the USB and also regulates this power rail to 3.3 V for eZ-FET operation and 3.3 V to the target side of the LaunchPad.
Hardware www.ti.com 2.4 Measure MSP430 Current Draw To measure the current draw of the MSP430FR6989 using a multi-meter, use the 3V3 jumper on the jumper isolation block. The current measured includes the target device and any current drawn through the BoosterPack headers. To measure ultra-low power, follow these steps: 1. Remove the 3V3 jumper in the isolation block, and attach an ammeter across this jumper. 2.
Hardware • • www.ti.com CTS (if hardware flow control is to be used) RTS (if hardware flow control is to be used) This wiring can be done either with jumper wires or by designing the board with a connector that plugs into the isolation jumper block. 2.7 BoosterPack Pinout The LaunchPad adheres to the 40-pin LaunchPad pinout standard. A standard was created to aid compatibility between LaunchPad and BoosterPack tools across the TI ecosystem.

Resources www.ti.com Figure 13. Directing the Project>Import Function to the Demo Project Selecting the \CCS subdirectory also works. The CCS-specific files are located there. When you click OK, CCS should recognize the project and allow you to import it. The indication that CCS has found it is that the project appears in the box shown in Figure 14, and it has a checkmark to the left of it.
Resources www.ti.com Figure 14. When CCS Has Found the Project Sometimes CCS finds the project but does not show a checkmark; this might mean that your workspace already has a project by that name. You can resolve this by renaming or deleting that project. (Even if you do not see it in the CCS workspace, be sure to check the workspace directory on the file system.) 4.1.

FAQs 5 www.ti.com FAQs Q: I can't get the backchannel UART to connect. What's wrong? A: • • • Check the following: Do the baud rate in the host terminal application and the eUSCI settings match? Are the appropriate jumpers in place on the isolation jumper block? Probe on RXD and send data from the host. If you don't see data, it might be a problem on the host side. • Probe on TXD while sending data from the MSP. If you don't see data, it might be a configuration problem with the eUSCI module.
