Flight controller using STM32F103

Documentation and demonstration video link

setup requirements

(for programming stm32f103 microcontroller)

• Linux debian (to use make build system and code upload tool stm32flash)
• sublime/vi/vim/gedit any texteditor
• ARM cross compiler toolchain
  • sudo apt-get install gcc-arm-none-eabi binutils-arm-none-eabi
• stm32flash to flash the controller, assuming the controller has default factory bootloader
  • sudo apt-get install stm32flash
• stm32f103 microcontroller, with default factory bootloader (must)
• usb to uart converter
  • PL2303HX, CP2102, ftdi etc

sensors

• mpu6050 sccelerometer and gyroscope
• hmc5883l magnetometer
• ms5611 barometer

additional accessories

• rc transmitter and receiver

STM32F10x Reference Manual

connections (from microcontroller)

• I2c1 {PB6, PB7} -> GY86 sensor {SCL, SDA}
• UART1 {PA10, PA9} -> UART debug port {RX, TX}
• {PB10, PB11, PB12, PB13, PB14, PB15} -> RC receiver
• {PA0, PA1, PA2, PA3} -> PWM to ESCs of corresponding motors (Left Front, Right Front, Left Back, Right Back) of Quadcopter

PCB designs

• You will find the .sch and .brd, QuadF32 flight controller board designs in the Eagle_CAD folder.
• It would also include a generated .cam file that I used for building my board, I would request you to use a different cam file provided by your pcb manufacturer.
• The folder also does include .lbr library for the stm32f103 module, that I am using.
