3.1 CapTIvate Design Center

To demonstrate the gesture tuning process, the CapTIvate Design Center (CDC) and TIDM-02004-BSWP-Demo.ser project is used. The MSP430FR2633 must be programmed with the TIDM-02004-Gesture-Demo firmware. The CapTIvate Design Center is available for download if not already installed. The CapTIvate Design Center was used to create the sensor configuration and application framework for the CAPT-BSWP panel. The resulting CapTIvate Design Center project, TIDM-02004-BSWP-Demo.ser, is located in the TIDM-02004 software download directory "DesignCenterFiles".

Connect the MSP430FR2633 MCU and CAPT-PGMR programmer with a USB cable to a PC. Launch the CapTIvate Design Center and open the TIDM-02004-BSWP-Demo CDC project. It should appear as shown in Figure 4. Double click on the user data log icon to open the oscilloscope plot view. Click the box labeled "Connected" to start communications with the CapTIvate Design Center.
