Introduction
Braking systems are among the most important safety-related functions in modern vehicles. Modern automotive electronic systems continuously monitor brake inputs and react in real time to ensure driver awareness and vehicle safety.
The course is based on the following Application Code Hub demonstrations:
Both examples implement the same brake monitoring concept and can be executed on either FRDM-A-S32K312 or FRDM-A-S32K344, allowing teachers, students, and developers to choose the platform that best fits their hardware availability and learning objectives. The demonstrations simulate a braking event using a Force Click board connected through the FRDM K64 Click Shield. The Force Click acts as a brake pedal sensor and generates an analog signal proportional to the applied pressure. This signal is acquired through the MCU ADC peripheral, processed by the application, and used to drive a 4x4 RGB Click board that provides visual indication of the current braking condition. The examples illustrate how automotive brake monitoring systems can detect braking events and react in real time using embedded software running on the S32K3 platform.

Course Objectives
After completing this course, participants will be able to:
- Understand the fundamentals of automotive brake monitoring systems
- Acquire analog signals using ADC peripherals
- Process brake-related inputs in real time
- Control visual indicators based on system status

Hardware Platforms and Components
Platform Selection
One of the advantages of this course is the flexibility to use either the FRDM-A-S32K312 or the FRDM-A-S32K344 platform. Both examples demonstrate the same automotive brake monitoring functionality and learning concepts, enabling users to select the board available in their laboratory environment while following the same workflow and development methodology.
FRDM K64 Click Shield
Provides mikroBUS™ connectivity for Click boards and simplifies hardware expansion.
Force Click
Simulates the brake pedal input by generating an analog signal proportional to the applied pressure. The ADC peripheral continuously reads this signal to determine the brake status.
4x4 RGB Click
Acts as the brake status indicator. Different LED patterns can be used to represent braking conditions and emergency braking events. The LEDs are controlled through the FlexIO peripheral.

System Architecture
The application follows a simple automotive workflow:
- The user applies pressure to the Force Click sensor.
- The ADC peripheral acquires the analog value.
- The application processes the braking signal.
- Brake status is evaluated against predefined thresholds.
- The 4x4 RGB Click LEDs are updated to indicate the current braking condition.
This workflow illustrates how sensors, software processing, and output indicators interact in a real-time automotive embedded system.
