尝试在Arduino 1.0中使用类并将SoftwareSerial设置为变量,但没有成功。
class SensorGPS: public Thread
{
private:
SoftwareSerial* serialGPS; // RX, TX
public:
SensorGPS()
{
serialGPS = new SoftwareSerial(10,11);
serialGPS.begin(4800);
}
}
serialGPS。Begin返回错误
arduino_sketch.ino: In constructor 'SensorGPS::SensorGPS()':
arduino_sketch:31: error: request for member 'begin' in '((SensorGPS*)this)->SensorGPS::serialGPS', which is of non-class type 'SoftwareSerial*'
arduino_sketch.ino: In member function 'virtual void SensorGPS::run()':
arduino_sketch:37: error: request for member 'read' in '((SensorGPS*)this)->SensorGPS::serialGPS', which is of non-class type 'SoftwareSerial*'
arduino_sketch:44: error: request for member 'write' in '((SensorGPS*)this)->SensorGPS::serialGPS', which is of non-class type 'SoftwareSerial*'
如果在设置变量
时删除*SoftwareSerial serialGPS(10,11); // RX, TX
变量
的结果错误arduino_sketch:21: error: expected identifier before numeric constant
arduino_sketch:21: error: expected ',' or '...' before numeric constant
这个问题适用于所有需要值作为初始化的类。另一个使用Dht11模块的例子(1);生成相同的错误
请注意示例Dht11库的相同问题。所以我改变了构造函数(库https://github.com/adalton/arduino/tree/master/projects/Dht11_Library)。
示例Dht11打开"Dht11.h"文件从<<strong>/strong>
Dht11(uint8_t newPin) : humidity(-1), temperature(-1), pin(newPin) { }
To(带setPin函数)
Dht11() : humidity(-1), temperature(-1), pin(-1) { }
void setPin(uint8_t newPin) {
pin = newPin;
}
所以现在在Arduino草图中,我可以在使用前设置引脚。这个解决方案对于大多数库都是可行的。
class SensorTemperatureHumidity: public Thread
{
private:
static const int Pin = 3;
Dht11 module;
public:
SensorTemperatureHumidity() {
module.setPin(Pin); // Set my pin usage
}
}
