    The latest version of SmartRF Studio can be downloaded from the Texas Instruments website [1]. 4.2 Installing SmartRF Studio and USB drivers Before your PC can communicate with the SmartRF TrxEB over USB, you will need to install the USB drivers for the EB.

  • Page 8: Virtual Com Port Usb Driver

    The driver for the Virtual COM Port (VCP) is typically located in the directory C:\Program Files\Texas Instruments\SmartRF Tools\Drivers\vcp, where C:\Program Files\Texas Instruments\SmartRF Tools\ is the root installation directory for SmartRF Tools such as SmartRF Studio. The path may be different if you have chosen a different installation directory for SmartRF Studio.

    SWRU294A The PC software that controls the SmartRF TrxEB + EM is SmartRF Studio. Studio can be used to perform several RF tests and measurements, e.g. to set up a CW signal and send and receive packets. The EB+EM can be of great help during the whole development cycle for a new RF product.

  • Page 11: Smartrf Transceiver Evaluation Board Overview

    6 SmartRF Transceiver Evaluation Board Overview SmartRF TrxEB acts as the motherboard in several development kits for low power RF ICs from Texas Instruments. The board has several user interfaces and connections to external interfaces, allowing fast prototyping and testing of both software and hardware.

    SWRU294A 6.2 MSP430 MCU The SmartRF TrxEB is equipped with an MSP430F5438A micro controller from Texas Instruments. Please see the MSP430F5438A product page [6] on the TI website for detailed information about this controller. All of the EB’s user interface peripherals are available to the MSP430 (Figure 3 on page 11).

  • Page 16: Battery Power

    SWRU294A 6.3.1 Battery Power The SmartRF TrxEB includes a battery holder for two 1.5 V AA batteries on the reverse side of the PCB. Normal AA batteries can be used and the onboard regulator supplies 3.3 V to the board. The power source selection jumpers should short circuit pin 1-2 (“BATT”) and 9-10 (“LCL”) of header P17,...

  • Page 17: External Power Supply

    SWRU294A 6.3.3 External Power Supply The SmartRF TrxEB has a connector for powering the board using an external power supply. The power source selection jumpers should short circuit pin 5-6 (“EXT”) and 9-10 (“LCL”) of header P16 as shown in Figure 9.

  • Page 18: Msp-Fet Power

    SWRU294A 6.3.4 MSP-FET Power The SmartRF TrxEB can be powered via an MSP430 debugger such as MSP-FET430UIF. The power source selection jumpers should in that case short circuit pin 7-8 of header P17 (Figure 12). Note that the MSP-FET will not power the EB if pin 9-10 of header P17 (“LCL”) is short circuited.

  • Page 19: Buttons

    SWRU294A 6.8 Buttons There are 7 buttons on the SmartRF TrxEB. Status of BTN_LEFT, BTN_RIGHT, BTN_UP, BTN_DOWN and BTN_SELECT can be read by the onboard MSP430. These buttons are intended for user interfacing and development of demo applications. The RESET MCU button resets the MSP430 MCU by pulling its reset line low (MCU_RESET_N). The RESET USB button similarly resets the USB controller (pulling USB_RESET_N low).

  • Page 20: Em Connectors

    SWRU294A 6.10 EM Connectors The EM connectors (TFM-110-02-S-D-A from Samtec), shown in Figure 13, are used for connecting an EM board to the SmartRF TrxEB. The connectors RF1 and RF2 are the main interface and are designed to avoid incorrect mounting of the EM board.

  • Page 26: Current Measurement Jumpers

    SWRU294A 6.12 Current Measurement Jumpers SmartRF TrxEB has three current measurement jumpers, MCU_PWR, IO_PWR and RF_PWR, as shown in Figure 18. By removing one of the jumpers, an ammeter can easily be connected to the board and perform current consumption measurements on the different segments of the EB. Similarly, a separate, regulated power supply for the EM can be connected.

    SWRU294A 7 Connecting an external MCU to SmartRF TrxEB You can easily connect an external MCU to a SmartRF TrxEB and use it to control the EM board mounted on the TrxEB. This chapter gives a quick overview over the signals that must be connected to enable your external MCU to control the EM.

  • Page 29: Connect Signals

    EM I/O signals on header P7 are located. NOTE: Transceiver EM boards from Texas Instruments share much of the same GPIO routing to the EM connectors. However, the number of GPIO signals available depends on the transceiver. Please refer to the schematics of your EM board for further details on the available GPIO.

  • Page 37: Updating The Firmware

    SWRU294A 11 Updating the firmware NOTE: This chapter only describes how to program the firmware on the USB controller on the TrxEB. To program the MSP430, use the MSP-FET430UIF tool and connect it to the FET430 connector on the EB. Programming can be done using IAR EW430, CCS or SmartRF Flash Programmer.

  • Page 38: Forced Boot Recovery Mode

    SWRU294A 11.1 Forced Boot Recovery Mode If the firmware update fails and the evaluation board appears to be dead, there is a way to force the board to only run the bootloader and stop all further execution. No attempts will be made to start the EB firmware.

  • Page 39: Board Resurrection

    SWRU294A 11.2 Board Resurrection If the forced boot recovery method above also fails, the board might be faulty or the flash on the CC2511 device has been inadvertently deleted. If the latter has happened, you can try to reprogram the boot loader on the CC2511. This will require that you have a CC Debugger [11].
  • Page 40 In the Device drop down list, select SmartRF05EB. The interface speed can be set to Fast. The flash image to program is C:\Program Files (x86)\Texas Instruments\SmartRF Tools\Firmware\TrxEB\usb_bootloader_trxeb.hex In the list of connected devices, you should see the CC Debugger connected to the CC2511.

  • Page 41: Frequently Asked Questions

    SWRU294A 12 Frequently Asked Questions I have a SmartRF TrxEB that says revision 1.1 on the PCB, but rev. 1.1 is not mentioned in the User’s Guide. Why? Your SmartRF TrxEB is what this document calls revision 1.3.0. This user’s guide refers to the assembly revision of the EB.
  • Page 42 SWRU294A switch gives the USB MCU access to extra EM I/O in SmartRF Mode, allowing support for combo EMs (e.g. CC1101-CC1190). See section 10.2 for further details on hardware changes in EB revision 1.7.0 and chapter. I have a CC1101-CC1190EM combo board. Will it work with SmartRF TrxEB and SmartRF Studio? Yes and no.
