Everything about STM32 drone development starting from the ground up

※ This class has been completely free since September 2022. This is the only class that teaches you how to develop the FCC flight control system for a high-performance STM32F4 DIY drone from start to finish using the free compiler STM32CubeIDE. Since you implement everything from the sensor interface to PID control without using drone open source such as ArduPilot or Pixhawk, you can experience and learn all the development processes of the drone control system and embedded system. We will explain all the source code and hardware assembly methods in the class slowly so that even non-majors and beginners can easily follow along. If you follow along slowly, you can experience more stable flight with your own drone that you developed yourself than with commercial products.

Hello, this is ChrisP from M-HIVE.

This course is about developing a self-made drone using the STM32F4 Micro Controller. It covers the entire process from sensor interface to PID control for developing the drone's flight control system.

Unlike other drone development courses, this course uses STM32F4 to write all the source codes one by one , from the sensor interface to PID control. Since we implement all the functions one by one without using open source, you can easily understand the drone development process and embedded firmware development process.

In addition, the drone developed in this lecture is not inferior in performance to commercial products such as Pixhawk and Ardupilot, so it can be applied not only as a simple educational drone but also for research and industrial use . Also, the MH-FC V2.2 used in this lecture can be applied not only to drones but also to all moving unmanned vehicles , so it can be applied to systems such as unmanned cars!

The course consists of three parts and 12 chapters.

Part 1 covers the basics of FC (Flight Controller)

  • CH1. Building a debug environment for embedded system development
  • CH2. Sensor interface (BNO080 9-axis sensor, ICM-20602 6-axis sensor, LPS22HH barometric pressure sensor)
  • CH3. Receiving and parsing GPS data (M8N)
  • CH4. Receiver data reception (FS-i6 transmitter, FS-iA6B receiver)
  • CH5. Gas Setting (QAV210)
  • CH6. Motor Drive (Oneshot125 PWM)

Part 2 Communication and Additional Features

  • CH7. Additional functions (EEPROM, battery voltage check, gyro offset removal, BNO080 calibration)
  • CH8. Wireless data transmission and reception (transmission of aircraft status information and reception of control parameters, use of GCS for lectures)
  • CH9. Safety functions (Fail-safe, etc. functions for safety)

Part 3 Flight Control (PID Control)

  • CH10. PID control preparation
  • CH11. Roll, Pitch Control (Double PID)
  • CH12. Heading Control (Single PID)

It proceeds in this order.

This lecture uses the STM32F405RGT Cortex M4 microcontroller as the main processor, the BNO080 9-axis sensor for attitude control, the ICM-20602 6-axis sensor , and the LPS22HH barometric pressure sensor for altitude control. It also covers the UBLOX M8N GPS data reception for outdoor automatic flight. (However, altitude control and GPS control are not covered in this lecture.)

The goal of this course is to develop a high-performance drone, but it goes into more depth about the process of developing one.

It covers everything from the sensor data interface, which is the most basic step for drone flight, to PID Control for attitude control.

We will focus on the processes for developing embedded applications, and combine them to complete a drone flight control system.

We will always strive to provide useful video lectures.
