// See http://forums.leaflabs.com/topic.php?id=739&page=2

class HardwareResourceParams
{
public:
    HardwareResourceParams();

};


class HardwareResource
{
public:
    Start();
    Stop();
    Setup(HardwareResourceParams * params);

};


class DMABuffer
{

};

// There may be multiple ways of implementing DMA for variouss purposes

class DMABase : public HardwareResource
{
public:
    DMABase();

    buffer
};

// There may be multiple ways of implementing DMA for variouss purposes

// Class implementing DMA Reading with double bouffering
class DMAReader : public HardwareResource
{
public:
    DMAReader();

    int read(void * buffer, int n);
    buffer
};

// Class implementing DMA Writing with double bouffering

class DMAWriter : public HardwareResource
{
public:
    DMAWriter();

    int write(void * buffer, int n);

    DMABuffer buffer;
};

And finally we have:


class ADC : public HardwareResource
{
public:
    ADC(){ // }
        Setup(...);

        // read a single word
        int Read();
    };
}

class DAC : public HardwareResource
{
public:
    DAC(){ // }
        Setup(...);

        // Send a single word
        Write(int data);
    };
}
