About Flymaple

The Flymaple is our Quadcopter controller, based on Maple Project. It uses an STM32F103RET6 (ARM Cortex-M3) as the main MCU.

• 72MHz STM32F103RET6 ARM Cotex-M3 microcontroller (Based on Maple RET6)
• 64KB SRAM
• 512KB FLASH ROM
• ITG3205 3-Axis gyroscope
• ADXL345 3-Axis accelerometer
• HMC5883 3-Axis compass
• BMP085 Barometer
• 3x 6-Channel GPIO, used to control 6-channel ESC/Servo
• 3x 8-Channel GPIO, used to capture RC receiver output
• 2x USART (serial) ports ready for XBee and GPS devices
• 2x I2C interfaces ready for ultrasonic sensor altimeters
• Arduino Shield compatible female head interface (AREF, GND引脚空挂?)
• SWD/JTAG debugger compatible

NOTE: On most ARM chips (including the STM32F103), all pins can be treated as General Input/Output (GPIO), and all pins can have another re-defined function.

The following table shows their main functions in the Flymaple, and other functions defined by STM32F103 in the remarks column. Original STM32F103 pin numbers are provided for further testing.
