| 摘 要： | 舵机控制器是无人飞行空中机器人中的一个重要设备。本文提出了利用ATmega 16L AVR嵌入式微控制器产生5路PWM信号控制JR舵机的方法。利用定时器的输出比较功能分时产生每路PWM信号的上升沿和下降沿，分辨率达到0.125us。通过测量接收机信号实现了手自动的无扰动切换，通过RS232接口实现了上住机对舵机的控制。

| Abstract: | Servo controller plays a very important role in unmanned aerial vehicle (UAV).An approach that generates 5 pulse-width modulation waves with ATmega16L AVR embedded microcontroller for the controlling of JR servos is described in this pa per.With the output compare function of timer,the rising edge and the falling edge of each PWM wave whose resolution reaches 2us are generated by the mechanism of timesharing.The bumpless transfer is realized by measuring the signals of receiver and the servo control of epigyny computer is realized via RS232 interface. |
