标题: １ｍｓ中断
清华的1ms中断里面的AD数据，速度数据是怎么获得啊？求高手讲解一下啊
void TI1_OnInterrupt(void){
int i;
g_nSpeedControlPeriod ++;
SpeedControlOutput();

g_nDirectionControlPeriod ++;
DirectionControlOutput();

if(g_n1MSEventCount >= CONTROL_PERIOD) {
      g_n1MSEventCount = 0;
      GetMotorPulse(); 读取两个电极脉冲计数值
} else if(g_n1MSEventCount == 1) {
      for(i = 0; i < INPUT_VOLTAGE_AVERAGE; i ++)
         SampleInputVoltage();//这个应该是ＡＤ数据处理吧
} else if(g_n1MSEventCount == 2) {
      GetInputVoltageAverage();
      AngleCalculate();
      AngleControl();
      MotorOutput();
} else if(g_n1MSEventCount == 3) {
      g_nSpeedControlCount ++;
      if(g_nSpeedControlCount >= SPEED_CONTROL_COUNT) {
         SpeedControl();
         g_nSpeedControlCount = 0;
         g_nSpeedControlPeriod = 0;
      }
} else if(g_n1MSEventCount == 4) {
      g_nDirectionControlCount ++;
      DirectionVoltageSigma();
      if(g_nDirectionControlCount >= DIRECTION_CONTROL_COUNT) {
         DirectionControl();
         g_nDirectionControlCount = 0;
         g_nDirectionControlPeriod = 0;
}
}

其实我都不知道他g_n1MSEventCount 这个变量是怎么变化！！！！

嗯，那个变量是用来控制每次进入中断时是执行那一部分命令的
