helicopter_externproj

The Source Code of Coaxial dual rotor helicopter flight control for a external project.

main controller ic: GD32F130G6U6, cortex-m3@48MHz, FLASH Size: 32KB, SRAM Size: 4KB.

development IDE: Keil MDK uVision V5.24.2.0 .

Toolchain: MDK-ARM Plus Version: V5.24.1 .

RF Processor: TI CC2530, 2.4-GHz IEEE802.15.4 ZigBee SoC.

IMU Sensor: Invensense MPU6500 Motion sensor.

Steer Motor Driver Chip: DRV8833, a dual H-bridge motor driver ic.

NOTE:

the frequency of high speed crystal oscillator on flight-controller main-board is 12MHz, and the processor core operating at 48MHz frequency, so you have to modify the 'HXTAL_VALUE' macro in file 'gd32f1x0.h' to '((uint32_t)12000000)', so that the mcu can run steadily.
