实现SPI总线的EEPROM读取数据,PWM控制电机，以及 uart口的读取陀螺编码器数据等(28335 SPI EEPROM PWM CAN PID control servo control used in the bush DC motor;AD sample and CAN process)

利用dsp28335的pwm控制直流力矩电机，实现俯仰和航向轴的定位、随动控制。(Using the PWM of DSP28335 to control the DC torque motor, the positioning and servo control of pitch and heading axis are realized.)
