Development Of Flight Controller For Drones By Using MCU

Abstract

This study focuses on the development of a flight controller for drones, utilizing both classic PIC microcontrollers and dsPICs to optimize performance. The main objective is to design and implement an embedded system capable of ensuring stable and precise control of a drone in flight. The approach includes the integration of inertial sensors (accelerometers, gyroscopes) through the I²C communication protocol, the implementation of PID control loops, and programming the microcontrollers using MikroC and MikroC Pro for dsPIC. Data acquisition and interaction with sensors were handled via I²C and UART, ensuring accurate and synchronized measurements essential for flight stabilization. Tools such as SerialPlot, Docklight, and Advanced Serial Port Terminal were used for real-time data visualization and analysis during the testing phases. The project combines modeling, simulation, and hardware/software implementation, with successive tests conducted to validate the controller’s stability and responsiveness. The results demonstrate that the developed system effectively stabilizes the drone’s main axes while addressing real-time processing constraints and precise sensor calibration. This study highlights the complementarity between PIC and dsPIC microcontrollers in meeting the demands of complex embedded systems, providing a concrete contribution to the development of compact, reliable, and scalable flight controllers applicable in aeronautics and robotics.
