新手问题（又出现了一个编程错误的问题）

hetzenauer

今天收到apc220无线传输模块，但是设置好了以后使用下载的RF-ANET软件却一直跳出错误提示，说没有发现串行端口，更新了驱动程序以后还是老样子，去硬件管理器里面看了串口是正常的，不知道怎么才能解决。
另外一个问题是今天做履带底盘前进后退程序的时候，我根据《arduino开发实战指南》里面的程序烧入之后，发现只有用USB线连接电脑的时候芯片才正常工作，如果不连接电脑只连接电源的话就只是间断前进，不知何故，希望各位高人不吝赐教。多谢


编写MotorCar库的时候又出现问题，我在头文件MotorCar.h里面已经定义了私有函数_speedLeftPin,_speedRightPin,_dirLeftPin,_dirRightPin以及公有函数MotorCar（int，int，int，int），forward，back，turnLeft，turnRight，turnLeftOrigin，turnRightOrigin，stop，但是在试运行的时候，编译时提示cpp里面每个子函数都有问题

#include <MotorCar.h>

MotorCar::MotorCar(int _slpin,int _dlpin,int _srpin,int _drpin)
{
  _speedLeftPin=_slpin;
  _speedRightPin=_srpin;
  _dirLeftPin=_dlpin;
  _dirRightPin=_drpin;
  pinMode(_speedLeftPin,OUTPUT);
  pinMode(_speedRightPin,OUTPUT);
  pinMode(_dirLeftPin,OUTPUT);
  pinMode(_dirRightPin,OUTPUT);
}
void MotorCar::forward(int _speed)
{
  digitalWrite(_dirRightPin,HIGH);
  digitalWrite(_dirLeftPin,HIGH);
  analogWrite(_speedRightPin,_speed);
  analogWrite(_speedLeftPin,_speed);
}
void MotorCar::back(int _speed)
{
  digitalWrite(_dirRightPin,LOW);
  digitalWrite(_dirLeftPin,LOW);
  analogWrite(_speedRightPin,_speed);
  analogWrite(_speedLeftPin,_speed);
}
void MotorCar::turnLeft(int _speed)
{
  digitalWrite(_dirRightPin,HIGH);
  analogWrite(_speedRightPin,_speed);
  analogWrite(_speedLeftPin,0);
}
void MotorCar::turnRight(int _speed)
{
  digitalWrite(_dirLeftPin,HIGH);
  analogWrite(_speedLeftPin,_speed);
  analogWrite(_speedRightPin,0);
}
void MotorCar::turnRightOrigin(int _speed)
{
  digitalWrite(_dirRightPin,LOW);
  digitalWrite(_dirLeftPin,HIGH);
  analogWrite(_speedRightPin,_speed);
  analogWrite(_speedLeftPin,_speed);
}
void MotorCar::turnLeftOrigin(int _speed)
{
  digitalWrite(_dirRightPin,HIGH);
  digitalWrite(_dirLeftPin,LOW);
  analogWrite(_speedRightPin,_speed);
  analogWrite(_speedLeftPin,_speed);
}
void MotorCar::stop()
{
  analogWrite(_speedRightPin,0);
  analogWrite(_speedLeftPin,0);
}

HIGH,LOW,pinMode之类的我怎么定义啊，这不应该是原本就自带的么

第一个问题我没有遇到，不太清楚。第二个问题我刚好跟你相反，USB连线时，小车间断前进，必须使用外部电源。原因在于USB提供的电流不够大，导致系统不断的复位。所以可能是你的外部电源提供的电流有些小导致的吧，你可以尝试换个外部电源，能够提供大的电流

我只连接电脑的时候和你一个情况,我估计就是电流不够,所以加了外接电源,结果两个同时插上的时候一切正常,拔了USB线以后就只能做一个动作了
