2 Requirements & First Steps
2.1 System Requirements
Minimum:
- Microsoft Windows 10 (coming to end of life) OR Microsoft Windows 11 (supported)
- 1 GB free HDD / SSD space
- micro USB to type A cable
- FTDI Chip USB driver (VCP) [1]
Recommended:
- active USB hub with at least 1000mA output current - some radar front ends need more power than provided by USB ports(!)
- 8 GB RAM or more
2.2 Software Requirements
Graphical User Interface (WebGUI):
- Java - compatibility matrix [2]
- Mozilla Firefox - compatibility matrix [3]
- Com2WebSocket / WebGUI software by indie Radar Sensors & Systems [4]
For firmware updates over UART / USB:
For firmware updates with an external debugger, without SiRad Easy r4 Breakout Board:
- Debugger: STLINK-V3MINI [7]
- micro USB to type A cable
- ST-LINK USB driver (STSW-LINK009) [8]
- ST-LINK Utility (STSW-LINK004) [9]
For firmware updates with external debugger and SiRad Easy r4 Breakout Board:
- Debugger: STLINK-V3MINI [10] OR STM32 Nucleo-64 development board [11]
- micro USB to type A cable (STLINK-V3MINI) OR mini USB to type A cable (Nucleo-64)
- (Nucleo-64 only) 6pin jumper cable (female-female) OR self-made programming cable
- ST-LINK USB driver (STSW-LINK009) [12]
- ST-LINK Utility (STSW-LINK004) [13]
2.3 Recommended Software
3 Hardware
- Ecosystem[17]
- Accessories List [18]
- TRA_120_002 SiRad front end datasheet [19]
- TRX_120_001 SiRad front end datasheet [20]
- Schematics [25]
3.1 Data Connection via USB Cable (USB Mode)
- Connect a USB cable (micro-B to Type A). An LED will light up to show that the board is powered and working.
- In some cases, the ST-LINK USB Driver may not work if an additional COM port number is not visible in Device Manager after the Evaluation Kit has connected. Installing a different Virtual COM Port Driver, as mentioned in the requirements, could be the solution.
Please see Evalkits r4 Software/Firmware section for detailed information on connecting the EvalKit (SiRad GUI, WebGUI, or Terminal program).
3.2 Mounting the Lens (Optional)
Please see lens datasheet [26] for more information.
