I ran this code (same as yours but a couple of minor changes that would make no difference) String cmd Just for completness, hereвЂ™s my stripped down arduino code String cmd

Is there a way of debugging whatвЂ™s going on in the Atmega328, in terms of setup of the serial interface? I am starting to believe that there might be something wrong with the setup of the serial interface (bit settings for clock divider etcвЂ¦) I finally broke down the arduino code to just about the smallest piece I could imagine, including a handshake to prevent buffer overflow etcвЂ¦ I still see the communication dying at 38400 Baud.

Note that there is a 5 second delay on the arduiono side to give you a chance to launch the processing sketch before the first data is send from arduinoвЂ¦Дoes anyone have some more ideas how to tackle this problem? Println('Received command word : '+ inString) Text('received: ' + displayString, 10,50)

Int val // Data received from the serial port HereвЂ™s the new protocoll based test code for Arduino: String cmd ДЄnd for the processing side: import rial.* As soon as I use the 38400 Baud speed, the data seems to get lostвЂ¦ I just changed my two sketches to wait for eachother to complete a command. MyPort = new Serial(this, portName, BAUDRATE) String inString // Input string from serial port: Serial myPort // Create object from Serial class The processing side sends an command string to the arduino and there it is returned with a _OK added.ДЄs soon as I use a speed above 19200 (28800 even crashes) the processing side always claims to receive вЂњnullвЂќД¬ould someone please try those two sketches at a high Baud rate?ДЄnd this one goes into Processing: import rial.* I have a sketch for arduino and one for processing with the exact wrong behavior. I managed to strip down my Problem to a simple example that does not need Qt.

How does Python import docker-compose.Thanks for the hints so far.

I use a 1-second timer to read the data in the buffer.Дata sending and receiving are as follows:ДЄddress android array assembly attribute Browser c Catalog Character string Client code command configuration file css data data base Database Edition element Example file function html html5 ios java javascript linux Memory method Modular mysql node object page parameter php Plug-in unit project python Route source code The server Thread user Recent Posts After the parameters are set, you can read and write the data through the read () and write () functions. You need to open the serial port before setting the serial port parameters. Qmessagebox:: about (null, 'prompt', 'serial port is not open!') My_serialport->setStopBits(QSerialPort::OneStop) Д¬onnect(timer, SIGNAL(timeout()), this, SLOT(readComDataSlot())) My_serialport->setFlowControl(QSerialPort::NoFlowControl) My_serialport->setParity(QSerialPort::NoParity) My_serialport->setDataBits(QSerialPort::Data8)

My_serialport->setBaudRate(ui->cmbBaudRate->currentText().toInt())

If(my_serialport->open(QIODevice::ReadWrite)) Open the serial port in read-write mode

My_serialport->setPortName(ui->cmbPortName->currentText()) If (UI - > btnopen - > text() = 'open serial port') If you want to manually select, you can add the serial port name to the combox in the form of a list and select it when you use it. Here, the serial ports we need to use are added to the combox by traversing all serial ports. StopBitsListcmbStopBits->addItems(stopBitsList) Paritylist cmbParity->addItems(parityList) ДataBitsListcmbDataBits->addItems(dataBitsList) Close the serial port and wait for it to be opened manually (open the serial port button) QDebug()cmbPortName->addItem(info.portName())
