4.2.1 Programming

The following sections describe how to setup, compile and download firmware to the ZC (Section 4.2.2), the ZED node (Section 4.2.3), and the GPD node (Section 4.2.4). The default settings for the switch example project have power saving disabled; hence, the following instructions describe how to set up the project with power saving enabled on the ZED to allow it to go into standby mode, which consumes approximately 0.8 μA.

To follow the detailed description for the measurement setup below, the correct software (SimpleLink CC13X2/CC26X2 SDK and CCS) must be installed. For details, see Section 3.2.1.

For this application report, the LaunchPad boards that run the application are programmed by simply connecting them to the PC via a micro-USB cable included with the LaunchPad. When connected in such a way, the debug feature in CCS can be used to program the devices, as CCS will automatically program the device connected with the current project open in the Project Explorer for debugging (after compiling the project, if any changes occurred). Then, simply stop the debugging process in CCS and the firmware will remain on the LaunchPad. For more details, see the Z-Stack 3.3.1 Quick Start Guide[6].

The LaunchPad programmed as a ZED can then have all jumpers removed from the board, and wired up to the DC Power Analyzer for power measurement analysis, which is shown in Figure 3.
