Queue send frames in synchronous serial comm

Damian7546

Hi,

I must queued frames to send.

I am currently doing it as below
QQueue<QByteArray> queueFrameToSend;

and adding to queue like below:

queueFrameToSend.enqueue(sendBuffer);

It is possible adding two parameter like below:
queueFrameToSend.enqueue(QByteArray, quint8 );

How do this ?

I too do not understand what you are still asking. If you want to put a QByteArray and a uint8 into the queue, as a single item, why don't you use the struct approach both @SGaist & @jsulm have suggested? What is the problem with that? You can create the struct in MyFunction::transaction(const QByteArray &data,quint8 reqType) if you wish to retain a function which accepts them as separate parameters.

If, for some reason, you are asking whether you can have two different typed items in a QQueue, one a QByteArray and another a uint8, then you cannot, what type would the QQueue<...> be?

Hi,

What is that second parameter ?
In any case, yes you can: use a struct.

struct Frame 
{
    QByteArray data;
    uint8 value;
};

QQueue<Frame> queueFrameToSend;

@SGaist and exactly like this:

struct Frame 
{
    QByteArray data;
    quint8 value;
};


Frame myFrame;
QQueue<myFrame> queueFrameToSend;

do i need to declare my struct, right ?

@Damian7546 said in Queue send frames in synchronous serial comm:

QQueue<myFrame> queueFrameToSend;

This is wrong. What @SGaist suggested is correct. I don't know what you're trying to achieve with your invalid C++ code.
To add a frame to the queue:

struct Frame 
{
    QByteArray data;
    uint8 value;
};

QQueue<Frame> queueFrameToSend;

Frame myFrame;
queueFrameToSend.enqueue(myFrame);

@jsulm In below function I would like to add two parameters to send queue, Now I have like below:

void MyFunction::transaction(const QByteArray &data,quint8 reqType)
{
queueFrameToSend.enqueue(sendBuffer);
queueType.enqueue(reqType);

}
