It achieves this by interpreting magnetic field variations detected by a Hall sensor mounted near a stationary model car, caused by magnets mounted on another model car approaching on a conveyor belt driven by a 12 VDC gearbox motor with 40 RPM and high torque. The goal of the training kit is to support firmware development of blind-spot applications using the SPC5-Studio integrated development environment with AutoDevKit plugin extension, which includes the source code. The system can be tested using the STSW-BLINDSPOT firmware downloadable from www.st.com.

These warning systems detect the presence of vehicles in blind-spot zones and alert the driver. In this simulation kit, the system consists of a plexiglass structure to simulate the loads and a set of boards to drive the application (AEKD-BLINDSPOTB1). Two cars are placed on the demo: one is stationary, while another car with embedded magnets moves on the conveyor belt driven by a gear-DC motor. A Hall sensor under the belt measures the magnetic field around it and a LED near the stationary car indicates when the blind-spot warning signal is triggered. The application is controlled by: • a 32-bit automotive microcontroller (SPC58EC80E5) • a VIPower actuator board (EV-VN7050AS) with a high side driver used to drive the conveyor belt geared DC motor • a LED driver board (AEK-LED-21DISM1) drives the warning LED Figure 1.
