Training Project on Implementing a State-Controlled Gear selection with a LED feedback powered by STM32 Nucleo

This repository consists of folders containing the MATLAB and Simulink files based on the following examples and projects:

• Model Finite State Machines
• MAKE ARDUINO RGB REV LIGHTS w SIMHUB

Prerequisites

Knowledge	Level
Matlab	⭐
Simulink	⭐⭐
Stateflow	⭐⭐⭐

Note: We recommend completing the Getting Started with Simulink Coder Support Package for STMicroelectronics Nucleo Boards example.

Required Hardware

• Supported STMicroelectronics Nucleo board
• USB cable type A to Mini-B cable

The goal 🎯

The purpose of this project is learn how to combine Simulink, and Stateflow and how we cane use them to control a gear selection system with a LED feedback coming from a NUCLEO-L476RG board.

Tasks

• Implement a simplified State-Controlled Four-Gear Selection based on the Automatic Transmission Controller example.
• Each time a gear is scaled up/down the LED should blink once.
• Once the the system reaches the last gear and the engine is revving, the LED should blink quickly.

Optionals:

• The intensity of main LED (PIN 13) should be managed proportionaly to the current gear selected.
• If you own an RGB LED stripe you can use it instead of the main LED.

Main Flow

This section shows the main steps I followed to achieve the goal.

Learn

• Simulink onramp
• Stateflow onramp
• Simulink Coder Support Package Using STMicroelectronics Nucleo Boards

Code

1. Simulink-Stateflow implementation of the Gear Logic
2. Implementing the LED bliking logic
3. Code generation and deployment on STM32 Nucleo

Note:

• Each folder contains a README that shows the main work of the relative step.
• All the sources in this repository have been tested on Matlab R2021a.
