CAN Class inheritance

Hello

I am trying to implement CAN with mbed as on of the nodes. I created the following three classes:

class myCanSignal { stores signal attributes such as min value, max value ,bit position, length,value etc.} class myCanMessage { array of signals,ID,format,type,length,Data, etc} class myCanBus{ speed,address}

In order to send CAN messages from mbed, I defined "myCanMessage" as a child of the mbed class CANMessage and "myCanBus" as a child to mbed class CAN respectively. The problem that I am facing is my classes are unable to inherit the member functions of the mbed classes.

Following is one of the instances where i see this error:

constructor myCanBus::myCANBus(PinName rd,PinName td) : CAN(rd,td) frequency(Bauud_rate); }

Compiling this code I get an error that frequency is an unknown identifier (frequency is a member function of class CAN). Is this the wrong way to inherit member functions of an mbed class?

It's hard to tell where the problem is without seeing your code. Are you inheriting from CAN in your header file like this?

class MyClass : public BaseClass
{
 
public:
    //Your declarations here

};
