QTR-RC Sensor Driver(STM32F4) and PID Implementation

This repository provides an implementation of a custom QTR-RC sensor driver for the STM32F4 microcontroller and integrates a PID (Proportional-Integral-Derivative) controller to manage motor movement based on sensor data in a line-follower application. This project is noteworthy as it introduces a QTR-RC sensor driver compatible with STM32F4, which is currently unavailable elsewhere.

Project Structure

The repository is organized into the following folders:

1. QTR_RC_Driver

   • Contains the implementation of the QTR-RC sensor driver for STM32F4, Successfully tested on STM32F446RE Board.
   • This folder includes essential files for configuring GPIO pins, reading raw sensor values, calibrating the sensors and reading calibrated sensor values.

2. PID_implementation For Line-follower Application

   • Contains the PID controller code responsible for adjusting motor speeds based on sensor input to maintain desired movement patterns.
   • The PID controller calculates error calculations based on sensor feedback, which requires correction to keep the robot on track, enabling smooth and responsive navigation.
   • Includes functions to manage motor speed and directional adjustments based on PID output.

Key Features

• Custom QTR-RC Sensor Driver: A newly developed driver for QTR-RC sensors, specifically tailored for the STM32F4 series.
• PID-Controlled Motor Speed Adjustment for LineFollower Robot: Real-time PID-based adjustments to motor speeds, allowing precise control over robot movement.
• Modular Structure: Organized into separate modules for sensor interfacing and control logic, making it easy to maintain and expand.
