The eZ430-RF2500-SEH Sensor Monitor is a full demonstration application that includes both the

firmware for the MSP430 that takes into consideration the constraints of running in an energy harvesting

environment as well as a PC application that can display all connected wireless nodes and the data that

they are reporting. Both the MSP430 firmware and the PC application (both binary and full source) are

included in SLAC219.

4.1

MSP430 Firmware

The eZ430-RF2500-SEH Sensor Monitor firmware is preloaded on the MSP430 devices and consists of a

wireless temperature sensor network and may be reprogrammed at any time. The network consists of an

Access Point that measures its own temperature and also receives data from End Devices. End Devices

measure their own temperature periodically and then enter low-power mode to reduce energy

consumption. The Access Point receives the information and transmits it to the PC through USB.

SimpliciTI™ is the RF network protocol used to establish the network. For more information on SimpliciTI,

4.1.1 Downloading Firmware to the MSP430

The firmware comes preloaded onto the MSP430 devices; however, it can be restored with the following

steps. The source code will be installed on the PC with the setup program included in SLAC219.

1. Open Code Composer Essentials v3.1.

2. Open any available Workspace.

3. Import the project to the Workspace.

(a) Click Project > Open Existing Project > Browse.

(b) Navigate to the source code location. The default location is

C:\Texas Instruments\eZ430-RF2500-SEH_Sensor_Monitor-v1.5\CCE_Source.

(d) Click Finish.

4. Set up the Linked Resources.

(a) Navigate to Window > Preferences... > General > Workspace > Linked Resources.

(b) Click New...

(d) Click the Folder... button and navigate to the source code installation root. The default location is

"C:\Texas Instruments\eZ430-RF2500-SEH_Sensor_Monitor-v1.5\CCE_Source".

If the Sensor Monitor demo is upgraded to a later version, the version number must be reflected in

the DEV_ROOT location.

(e) Click OK twice until the original CCE screen is displayed.

5. Connect one of the eZ430-RF2500T target boards to the eZ430 Emulator and plug it into a USB port

on the computer.

6. Right-click the project name "SEH Sensor Monitor" in the C/C++ Projects window and click Active Build

Configuration > End Device - Debug.

7. Click Project > Clean...

8. Click Run > Debug Active Project.

9. Click the Terminate button (red square in the top left 'Debug' view) to terminate the debugging session.
