Communicating With Serial Port In CThis article will demonstrate how to write and receive data from a device connected to a serial port in C and. NET. We will be writing the received data to a Text. Box on a form, so this will also deal with threading. In the past, to communicate with a Serial Port using. Net 1. 1, you had to either use the Windows API, or use a third party control. Atheros Module. With. Net 2. 0, Microsoft added this support with the inclusion of the Serial. Port class as part of the System. IO. Ports namespace. Implementation of the Serial. Grand Theft Auto Vice City Softonic. Port class is very straight forward. Im developing a project that has a number of hardware sensors connecting to the deployment machine through RS232 serial ports. But. Im developing on a machine. Multiple threaded callback interrupts in Python. Weve been learning about interrupts this week because of the brand new interrupt capabilities of RPi. GPIO. This article shows how to communicated with Serial Port using C. ESP8266 AND MICROPYTHON D. A.

To create an instance of the Serial. Port class, you simply pass the Serial. Port options to the constructor of the class                         Serial. Port serial. Port  new Serial.

Once you are ready to use the Serial Port, you will need to open it Now we are ready to receive data. However, to write this data to the Text. Box on a form, we need to create a delegate. Net does not allow cross thread action, so we need to use a delegate. The delegate is used to write to the UI thread from a non UI thread. Set. Text. Delegstring text  We will now create the spData.

Some devices will send data without being prompted. However, some devices need to be send certain commands, and it will reply with the data that the command calls for. For these devices, you will write data to the serial port, and use the previous code to get the data that will be sent back. In my example, I will be communicating with a scale. For this particular scale, sending the command SIrn will force it to return the weight of whatever is on the scale. This command is specific for this scale. You will need to read the documentation of your serial device to find commands that it will receive. To write to the serial port, I have created a Start button on the form.
