How to Store Multiple data using Serialport in QT

Hemalatha Gajula

void MainWindow::readData() // CH1 and CH2 Data Logic implementation
{

// int r1,r2,r3,r4 = 0;
//int m,n,x,y = 0;
// int num3, num4 = 0;
// QByteArray RX_Data[6] = {0,0,0,0,0,0};
QByteArray UART_Data[5] = {0,0,0,0,0};
int k;
QByteArray data;

 for(k=0; k<5; k++)
 {
     data= serialPort->readAll();
     ui->plainTextEdit_3->insertPlainText(data);
     UART_Data[k] = data;
     ui->plainTextEdit_2->insertPlainText(UART_Data[k]);
 }

// for(k=3; k<5; k++)
// {
// ui->plainTextEdit_3->insertPlainText(UART_Data[k]);
// }

// ui->plainTextEdit_3->insertPlainText(UART_Data[4]);

Hi and welcome to devnet,

That code won't work as QSerialPort is asynchronous by default.

What is your end goal ?
