クラス内から関数ポインタ渡し

Posted at
Serial.h
void attach (void(*fptr)(void), IrqType type=RxIrq);

template<typename T>
void attach (T *tptr, void(T::*mptr)(void), IrqType type=RxIrq); 
controler.h
class Controler {
public:
    Controler(PinName pinTx, PinName pinRx);

private:    
    Serial _device;
};
controler.cpp

void Controler::attachRx()
{
    rxBuffer[rxVolume++] = _device.getc();
}

Controler::Controler(PinName pinTx, PinName pinRx) : _device(pinTx, pinRx) {
    Serial *p;
    p = &(_device);
    p->attach(this, &Controler::attachRx, Serial::RxIrq);
}

Controlerクラス内のvoid Controler::attachRx()を関数ポインタ渡しするため、
_device.attach(&attachRx, Serial::RxIrq);
と宣言しても通らなかったため、回避方法として。。。
