Motor Direction LEDs with Infineon FOC Demo

This project demonstrates how to enhance an existing motor control demo for Infineon's PSoC™ Control MCU by adding two external GPIO-controlled LEDs to indicate motor direction (forward or reverse). It serves as a simple and hands-on example of how developer-friendly the Infineon + ModusToolbox™ ecosystem is — even when working through the Eclipse IDE.

Project Overview

What It Does

• Adds two GPIO-driven LEDs that illuminate based on the motor’s direction:

  • Forward: one LED turns on
  • Reverse: the other LED turns on
  • Motor disabled: both LEDs remain off

Purpose

• Provides a visual indicator of motor behavior
• Demonstrates how to extend the FOC demo with custom I/O logic
• Highlights how straightforward it is to modify existing firmware

Where the Code Is

All customizations are located in:

<motor-control-project-root>/main.c

New code sections are clearly marked with:

// ADDED BY MOUSER ELECTRONICS

Custom Functions Added

• Init_LED_Pin() – Initializes GPIO pins for LED output
• Update_LED_State(bool motor_enabled) – Updates LED states based on motor status and direction

These functions are called from main() and operate alongside the motor state machine.

Expected Behavior

After flashing the updated firmware:

• The LEDs toggle based on the real-time motor direction.

• When the motor is disabled, both LEDs turn off.

• When the motor is running:

  • If direction is forward: one LED turns on
  • If direction is reverse: the other LED turns on

Requirements

• Infineon PSOC™ Control C3M5 Complete System Motor Control Kit (KIT_PSC3M5_MC1)

• Infineon Eclipse IDE (ModusToolbox-based)

• Two external LEDs connected to:

  • P0.0 (Reverse)
  • P0.1 (Forward)

• Base motor control project (provided in this repo)
