If You Need Assistance Support for the MSP430 device and the experimenter’s board is provided by the Texas Instruments Product Information Center (PIC). Contact information for the PIC can be found on the TI web site at www.ti.com. Additional device-specific information can be found on the MSP430 web site at www.ti.com/msp430. Note: IAR KickStart is supported by Texas Instruments Although IAR KickStart is a product of IAR, Texas Instruments provides the support for it.
1. Getting Started The MSP430FG4618/F2013 experimenter’s board is a comprehensive development target board that can be used for a number of applications. The MSP-EXP430FG4618 kit comes with one MSP430FG4618/F2013 experimenter’s board shown in Figure 1 and two AAA 1.5 V batteries. Figure 1: MSP430FG4618/F2013 Experimenter’s Board 2. Devices Supported The MSP430FG4618/F2013 experimenter’s board is based on the Texas Instruments ultra-low power MSP430 family of microcontrollers [1, 2].
4. Functional Overview The MSP430FG4618/F2013 experimenter’s board supports various applications through the use of the on-chip peripherals connecting to a number of on-board components and interfaces as shown in Figure 2.
5. Hardware Installation Power may be provided locally from two on-board AAA batteries, externally from a Flash emulation tool (FET), or an external supply. The power source is selected by configuring jumpers VCC_1, VCC_2, and BATT. PWR1 and PWR2 will supply power to each MSP430 independently. Appendix B has information on the exact location of these jumpers. Figure 3 shows the jumper hierarchy and configuration options.
6. Functional Overview This section contains information about the various on-board interfaces and their functionality and about the various peripherals enabling these interfaces. Wireless applications are facilitated using the MSP430’s capabilities to interface with the Chipcon wireless evaluation modules (CCxxxxEMK) from Texas Instruments. The on-board LEDs and LCD display are used for visual feedback.
6.2 Communication Peripherals The experimenter’s board supports numerous communication interfaces for onand off-board connections. 6.2.1 Chipcon Wireless Evaluation Module Interface Interface to the wireless world is accomplished via the Wireless Evaluation Module header supporting the CCxxxxEMK boards from TI. The transceiver modules are connected to the USART of the MSP430FG4618 configured in SPI mode. Libraries [6] that interface the MSP430 to these transceivers are available at www.ti.com/msp430.
6.3.1 Microphone The microphone is connected to the MSP430FG4618 and may be used for various applications. The microphone is enabled/disabled via a port pin connected to the MSP430FG4618. 6.3.2 Analog Filters An active first order high-pass filter (HPF) with a cut-off frequency set at approximately 340Hz follows the microphone to eliminate extremely low input frequencies.
6.4 System Clocks The experimenter’s board has various system clock options that support low and high frequencies. Each MSP430 has integrated clock sources as well as support for external connections. 6.4.1 MSP430F2013 Clock Sources The MSP430F2013 uses the internal VLO operating at ~12kHz for an ultra-low power standby wake up time base. The integrated DCO is internally programmable at frequencies up to 16MHz for high speed CPU and system clocking. 6.4.2 MSP430FG4618 Clock Sources A standard 32.
7. Frequently Asked Questions 1) What devices can be programmed with the experimenter’s board? The experimenter’s board is designed to develop applications using the MSP430FG4618 and MSP430F2013. These devices can be replaced by MSP430FG461x and MSP430F20xx device derivatives, respectively. 2) How is power supplied to the experimenter’s board? Three supply options exist: 2xAAA battery power, JTAG and external power supplies are supported.
8) Can I use two FETs to perform simultaneous access of the FG4618 and F2013 during program/debug? Yes, independent flash emulation tools (either USB or Parallel for ‘FG4618 and USB only for ‘F2013) can be simultaneously used to program the MSP430 target devices. When supplying power via the FET, it is recommended to use only one FET to source power. The second FET can sense this voltage level instead of supplying power, to avoid any voltage conflicts in-system.
Appendix A Configuring an IAR Embedded Workbench Project IAR Embedded Workbench may be used to program/debug the on-board MSP430 devices with custom firmware or provided sample code available at www.ti.com/msp430. Programming and debug is done using JTAG1 and JTAG2 providing access to the MSP430FG4618 and MSP430F2013 respectively. Steps to program each of these devices are shown in this section. It is assumed that the USB FET tool has been installed using the instructions provided in the FET User’s guide.
4. From the same menu under the Debugger option, select the FET Debugger shown as a snapshot in Figure A-2. Figure A-2: Selecting the FET Debugger 5. Then proceed to the FET Debugger option and choose the Texas Instrument USB-IF as shown in Figure A-3. The default setting of Automatic needs no change.
MSP430F2013 Programming 1. Connect the 14-pin cable to JTAG2 header on the board. 2. Create a new project or load a valid existing project on the IAR Embedded Workbench. 3. In IAR Embedded Workbench under the Project drop-down choose Options; this brings up the menu shown in Figure A-1. Under the General OptionsÆTarget choose MSP430F2013 from the MSP430x2xx Family option. 4. From the same menu under the Debugger option select the FET Debugger shown as a snapshot in Figure A-2. 5.
