5.5 Running the Software Application Examples
The CCMSP-EM boards come pre-programmed with a Packet Error Rate (PER) test
application, making it possible to e.g. perform simple range testing out of the box.
Running the PER test application:
1. Assemble the hardware as described in Figure 8 above. Remember to connect the
antennas.
2. Select an appropriate power source. The boards can be powered either via a USB
cable, by using a DC power or by using 2xAA batteries. Make sure that the power
selection jumper P11 chooses the appropriate power source (right position for
batteries, left for USB power or DC power). See details in section 7.3.
3. Power is turned on by switching position of the main power switch from OFF to ON.
4. Follow the instructions on the LCD by using the joystick to select modes and set up
one node as transmitter and one as receiver.
5. When the test starts, it displays a PER value and an RSSI value on the LCD on the
receiver node.
In order to program the MSP430 MCU on the CCMSP-EM430F2618 board the MSP-
FET430UIF (FET) is needed. Connect the FET to the JTAG connector P12 on the CCMSP-
EM430F2618 and to a PC with a USB cable. Use IAR Embedded Workbench for MSP430 to
download and debug.
