    5. Hardware Installation

    Power may be provided locally from twoon-board AAA batteries, externally from aFlash emulation tool (FET), or an external supply. The power source is selectedby configuring jumpers VCC_1, VCC_2, and BATT. PWR1 and PWR2 will supplypower to each MSP430 independently. Appendix B has information on the exact

    location of these jumpers. Figure 3 shows the jumper hierarchy and configurationoptions.

    Figure 3: Jumper Settings for Power Selection

    The battery jumper BATTis used to select the on-board batteries to power thesystem, independent of the FET connections. The user must ensure that thisvoltage meets the requirement for proper functionality of the MSP430.

    The power selection jumpers VCC_1and VCC_2select the power connectionsbetween the board and each FET interface. These jumpers are two rows of 3-pinheaders, one for each MSP430 on-board. VCC_1, the bottom row, is for theMSP430FG4618 and, VCC_2on the top row, is for the MSP430F2013. A jumperplaced on the rightmost 2-pins (FET) selects the JTAG FET as the power source.

    A jumper placed on the leftmost 2-pins (LCL) would enable local power (eitherfrom the batteries or an external supply) to be applied to each FET for proper logicthreshold level matching during program/debug.

    Headers PWR1and PWR2have been provided to enable power to the individualMSP430s. A jumper placed on PWR1provides power to the MSP430FG4618 anda jumper placed on PWR2provides power to the MSP430F2013. Individual devicecurrent consumption can be measured via each of these jumpers. Care should betaken that MSP430 interconnections are not made that could influence such a

    measurement.

    Once the required power selections have been made the experimenters board isready to be used. Both the MSP430FG4618 and MSP430F2013 are factoryprogrammed. After power up, the MSP430FG4618 executes an ultra-low powerreal-time clock displayed on the LCD. The MSP430F2013 pulses LED3 fromLPM3 using the VLO as a periodic wake-up time base.

    7. Frequently Asked Questions

    1) What devices can be programmed with the experimenters board?The experimenters board is designed to develop applications using theMSP430FG4618 and MSP430F2013. These devices can be replaced byMSP430FG461x and MSP430F20xx device derivatives, respectively.

    2) How is power supplied to the experimenters board?Three supply options exist: 2xAAA battery power, JTAG and external powersupplies are supported.

    3) Can I use the Parallel FET (MSP-FET430PIF) to program/debug theMSP430?The MSP4304618 supports the USB and Parallel Port FETs. TheMSP430F2013 is supported by the USB FET (MSP-FET430UIF) only. TheParallel Port FET does not support the Spy Bi-Wire program/debug modeused.

    4) I have erased and reprogrammed the MSP430; can I restore the factoryprogrammed-firmware on the device(s)?

    The software source files are available at the MSP-EXP430FG4618documentation page at www.ti.com/msp430.

    5) The MSP430FG4618 is no longer accessible via JTAG, is somethingwrong with the device?- Verify that the target device is powered properly

    - If the target is powered locally, verify Vcc is applied to pin 4 of the JTAGheader

    - If communication and power are correctly applied to the target and the issuepersists, it may be due to the MSP430FG4618 accidentally beingprogrammed with MSP430F2xx source code. In some conditions F2xxsource code loaded onto the FG4618 can configure the SVS module to

    monitor SVSIN (P6.7) and reset the device in case of a low voltage conditionexternally applied. Temporarily connecting P6.7 of the FG4618 to Vcc andreprogramming the target device with the valid source code will eliminate thisissue.

    6) Does the experimenters board protect against b lowing the JTAG fuse ofthe target devices?No. Fuse blow capability is inherent to all Flash-based MSP430 devices inorder to protect users intellectual property. Care must be taken to avoid theenabling of the fuse blow option during programming that would preventfurther access to the MSP430 device(s) via JTAG.

    7) I am measuring system current in the range of 30mA, is this normal?Current consumption of the system is dependent on the functions and

    operation of the hardware being performed. The RF connectivity and isolatedUART communication support, when used, can reach these currentconsumption levels. Take care that these elements are not accidentallyenabled, specifically the isolated UART, if such system currents are notexpected.

    8) Can I use two FETs to perform simultaneous access of the FG4618 andF2013 during program/debug?Yes, independent flash emulation tools (either USB or Parallel for FG4618and USB only for F2013) can be simultaneously used to program the MSP430target devices. When supplying power via the FET, it is recommended to useonly one FET to source power. The second FET can sense this voltage levelinstead of supplying power, to avoid any voltage conflicts in-system. Refer tosection 5 Hardware Installation for details regarding supported power supplyconfigurations.

    9) I cannot properly open the workspace and pro jects provided in the .zipfile with IAR, how can I open the sample code?The IAR workspace/projects included for the sample code provided has beencreated using IAR Embedded Workbench Version 3.42A. These projects arenot backward compatible with older IAR releases and will not open using priorversions. New workspace/projects can be created and the sample codesource files can be added manually in order to build these samples with olderversions. Instruction for setting up a project in IAR are described in the MSP-FET430 Flash Emulation Tool (FET) (for use with IAR v3.x) User's Guide,[5].

    10) I have loaded the FG4618 and F2013 sample code for the capacit ivetouch sensing application. It doesnt seem to be working, what is wrong?Verify that the correct jumper settings are used for H1 enabling the I2Ccommunication link between MSP430s. Make sure jumper JP2 is removed,disconnecting LED3 from the touchpad circuitry. When connected, the LEDcauses the measurement of the capacitive touch element on P1.0 to fail.
