How run code in the backround without stack in a loop?

[Alex_Spi13]

Hello I'm trying to make a ROS GUI for control my robot. I want to display the measurements that I subscribe from my robot and display to the lcds without press pushbutton, like running in the backround but not stack in a loop because I want rest functionality of the GUI .

Here is the measurements when I push the button start measurements

I want to run this code for example, every second .

void MainWindow::on_start_measurments_pressed()
{

        ui->left_ultrasonic_lcd->display(ultrasonic_msg.y );
        ui->middle_ultrasonic_lcd->display(ultrasonic_msg.x );
        ui->right_ultrasonic_lcd->display(ultrasonic_msg.z);
        ros_f->ultrasonic_subscriber();
}

Hi,

You can use a QTimer for that.
