With each 24 GHz radar, Infineon offers various radar demonstration applications to demonstrate the radar
kits’ capabilities and to facilitate the development of user applications that can be used to detect:
•Motion, speed and direction of movement of multiple targets (approaching or departing)
•Distance of multiple targets
•Position of multiple targets
2.1 Tools and software set-up
2.1.1 Infineon Developer Center (IDC)
Before using the 24 GHz radar demo boards, as well as running the radar demonstration application, it is
necessary to download the supporting software from Infineon.
In order to install and use Infineon plugins and tools, and gain access to the 24 GHz radar software package and
documentation, you must first download and install the Infineon Developer Center (IDC) Launcher (former
Infineon Toolbox) using this link: https://www.infineon.com/cms/en/design-support/tools/utilities/infineon-
developer-center-idc-launcher/
Figure 2 Run Infineon Developer Center Launcher

User can download and install the 24 GHz radar SW package following the steps on the “Getting started” page
of each installed tool via the Infineon Developer Center (IDC).
Once installed, a folder (e.g., IFX_D2GL-HW-SW_V1.0.0) will be created on the specified path with the following
structure:
•Firmware_Software –all software, firmware and drivers
•Hardware –all hardware-related files (e.g., schematics, Altium files)
•Documentation –all documentation (e.g., application notes)
2.1.3 XMC™ Flasher
The 24 GHz radar demonstration firmware is already pre-loaded in the Flash memory on the XMC™
microcontroller. This section describes how to use the binary images provided to reprogram the firmware
applications. In addition to XMC™Flasher, Radar GUI can also be used to flash new firmware into the device
which is explained in section 2.2.1. The 24 GHz radar firmware package contains binary images (*.hex) of the
applications provided in the subfolder Binary.
The XMC™Flasher tool can be used for on-chip Flash programming to reprogram the radar application using a
binary image, as follows:
•Connect the 24 GHz radar board to a PC with USB “type A to micro-B” cables through the embedded USB
connector to power up the board or to debug.
•Use (*.hex) binary with the XMC™Flasher tool to reprogram the radar firmware:
−Start the XMC™Flasher tool in the Infineon Developer Center (IDC) launcher

2.1.4 DAVE™ IDE
DAVE™(Digital Application Virtual Engineer), is a free-of-charge Eclipse-based Integrated Development
Environment (IDE) using a GNU C-compiler that provides an extensive, configurable and reusable code
repository for an XMC™industrial microcontroller powered by Arm® Cortex®-M processors.
It is a C/C++-language software development and code generation tool for XMC™microcontroller applications
using DAVE™APPs to configure the MCU peripherals (ADC, DMA, CCU4…), which reduces development time and
allows for quick porting of the firmware across XMC™-series MCUs.
DAVE v4.1.2 or higher should be installed, or any other third-party toolchain supporting Infineon Technologies
XMC™microcontrollers, e.g., Atollic, IAR, Keil MDK, Rowley or TASKING. The latest version of DAVE™IDE (v4.5.0)
can be downloaded from IDC using https://softwaretools.infineon.com/tools/com.ifx.tb.tool.daveide
2.2 Graphical User Interface (GUI) solutions
2.2.1 Radar GUI
Note: The Radar GUI tool is only supporting DEMO DISTANCE2GO, DEMO POSITION2GO, DEMO
SENSE2GOL PULSE and DEMO DISTANCE2GO 24GHz radar demo boards.
Radar GUI is a Java-based highly interactive GUI for Windows XP/Vista/7/8/10. It provides graphical support for
Infineon’s radar devices and enables the visualization of real-time raw IF quadrature output signals and FFT
spectrum and enables observation of the targets’ distance and velocity information from a connected 24 GHz
radar device.
Radar GUI offers several methods to record data in different formats for advanced signal processing and
supports multiple recording options. Each option saves corresponding data in a dedicated file, as follows:
•Raw data –records raw IF data as they are received from the device; data are stored in a file with .raw
extension
•Time domain data –records extracted time domain data (I/Q signals); data are stored in a file with .tdd
extension

2.2.2 Micrium µC/Probe™ XMC™ GUI
Note: The Micrium GUI tool is only supporting DEMO SENSE2GOL/MAKE 24GHz radar demo boards and is
not compatible with the Radar GUI.
µC/Probe™XMC™from Micrium® is a free-of-charge data monitoring and visualization tool to modify and track
real-time data on the XMC™target microcontroller in a non-intrusive way.
It enables designing a graphical dashboard with a wide range of widgets to control or fine-tune your XMC™
application, and it includes an eight-channel digital oscilloscope to visualize real-time data, controlled by a
dedicated code that runs on the XMC™target.
µC/Probe™XMC™is simple to install on a Windows PC and can be easily connected via the J-Link onboard
debugger integrated into most of the XMC™kits.
The latest version of µC/Probe™XMC™v4.3.0.9 is available for download from:

The Radar Sense2GoL software package comes with a GUI based on a µC/Probe™project from Micrium, which
helps the user process collected raw data.
Here below an example, on how to run this Micrium-based GUI project, for the Sense2GoL device:
•Go to the /Firmware_Software/GUI folder inside the locally installed S2GL-HW-SW package.
•Double-click the µC/Probe™S2GL_GUI.wspx project, to open the GUI.
•S2GL_GUI.wspx can be opened in Windows Explorer, or in S2GL_Doppler DAVE™project explorer, as shown
in Figure 19.
Figure 19 Open Sense2GoL Micrium GUI project
The µC/Probe™needs to be provided by the XMC™compiling and linking process output file (ELF file). This file
containing the name, data type and address of all firmware global variables is parsed by the µC/Probe™project.
A precompiled .elf file is already available in a /Firmware_Software/GUI folder called S2GL_Doppler.elf.
Note: After building a project, object files and an application binary file (typically in ELF format) exist in
the Debug folder in the Project Explorer view file tree. Please ensure you have imported the
S2GL_Doppler.elf file into your Micrium project each time you modify and build your
S2GL_Doppler project.
Once the GUI project has opened, the following steps need to be executed:
•Connect your DEMO SENSE2GOL board via USB (please ensure the USB port on the debugger board is
connected).
•Start the GUI by clicking on the Run button.

3Customizing radar applications
Firmware (FW) is a piece of software written in C language to control different ICs and peripherals via the host
processor, which is the XMC™Cortex™-M MCU embedded in Infineon’s 24 GHz radar demo boards.
The 24 GHz radar firmware is released as a ready-to-run DAVE™4 project, where source files are generated
based on the DAVE™APPs used, which are graphical-configurable application-oriented software components,
used to enable quick reuse and customization.
This section explains how to customize, build, Flash and debug radar applications built on generated DAVE™
code, and run them on the 24 GHz radar demo board.
3.1 Building, Flashing and debugging the DAVE™ project
After installing the DAVE™IDE, the user can start the program to build and load the 24 GHz radar firmware
applications as follows:
•Download and unzip the 24 GHz radar firmware package, making sure not to modify the package folder
structure.
•Open the project workspace with the DAVE™toolchain:
−Run the DAVE™toolchain and wait for the program to start, which asks for the workspace location.
−Enter a path or browse to the desired folder via the Browse… button and confirm the choice with the OK
button.
Figure 23 DAVE™workspace launcher
Note: It is recommended that the active workspace folder is located not too many levels below the file
system root to avoid build errors caused by exceeding the Windows path length character
limitations.
−Once the DAVE™workspace is opened, select Import... in the File menu to display the Import dialog box.
−Within the Import dialog box, select Infineon, DAVE Project and click on the Next button.
