Using Infineon’s radar baseboard XMC4700 and BGT24LTR11 radar shield with Arduino Set-up guide Software set-up Using Pulsed Doppler Radar Library The Pulsed Doppler Radar Library is installed as part of the core libraries for XMC when the XMC Arduino package is installed as shown in Section 3.2.
Page 13 Using Infineon’s radar baseboard XMC4700 and BGT24LTR11 radar shield with Arduino Set-up guide Software set-up Next, some steps are required to initialize the hardware for the Pulsed Doppler Radar and also to configure the parameters. All these are to be done within the setup() routine (Figure 13).

Figure 22 Uploading code onto board The application can now be tested. Make some movements in front of the radar board and observe the LED colors depending on the motion and its direction (Figure 23).
Page 21 Figure 24 Example sketch: RadarPulsedDopplerLED_Andee_RGB Navigate to Tools > Board > XMC4700 Radar Baseboard (as shown previously in Figure 10) to select the radar baseboard as the target kit. Compile the sketch by clicking the “Verify” button (Figure 25). A success message will be displayed on compilation completion (Figure 26).
Page 22 Attach the BGT24LTR11 shield to the radar baseboard XMC4700 Stack the RGB LED lighting shield with XMC1202 onto the radar baseboard XMC4700 via the Arduino stack headers (Figure 28). Also connect an RGB LED and a 24 V DC power adapter to the RGB LED lighting shield.
Page 23 Software set-up Figure 28 Stacking the RGB LED lighting shield onto the radar baseboard XMC4700 Stack the Annikken Andee U shield onto the set-up (Figure 29). Notice that there are several jumper wires on the Annikken Andee U board. This is due to the hardware modifications required on the radar baseboard regarding the ISCP header as mentioned in Section 2.3.
Page 24 Jumper wire connections on the Andee U Turn on the 24 V DC power supply to the RGB LED lighting shield and connect the radar baseboard XMC4700 to the PC via a USB cable onto the “Debug” USB port (Figure 31).
Page 25 Using Infineon’s radar baseboard XMC4700 and BGT24LTR11 radar shield with Arduino Set-up guide Software set-up Figure 32 Uploading the code onto the board The RGB LED should turn on with white light, while the on-board LED will cycle between red, green and blue light to show radar processing is taking place (Figure 33).
Page 26 Upon successful connection, the GUI should appear on the app (Figure 36). In case this does not happen, disconnect from the app, press the reset button on the radar baseboard XMC4700 and retry the connection. Make some movement in front of the radar board and observe the measured speed and detected direction on the GUI.
