Receiving data from serial port

If Serial. The function Serial. It can return the data byte which can then be stored in a variable or used for some condition check etc. The following statement shows how the data byte is read from the serial port and is stored into a variable.

The above statement should always appear after making a function call to the Serial. The variable could be of type integer or character. Unlike actually printing the data value in the serial port by sending the data byte after formatting it as ASCII character as the functions Serial. The code written for this particular project initializes the serial port with a baud rate of using the function Serial.

The code can check whether all the data bytes have been received or not before reading them with the help of the function Serial. Once the Serial. If it does return Nothing , exit the Do loop. Add an Else block to the If statement to handle the case if the string is actually read. The block appends the string from the serial port to the return string.

This code example is also available as an IntelliSense code snippet. In the code snippet picker, it is located in Connectivity and Networking. For more information, see Code Snippets. This example assumes the computer is using COM1. For more flexibility, the code should allow the user to select the desired serial port from a list of available ports. This example uses a Try The returned responses can be monitored and saved in a single log file that employs the first-in-first-out method.

Serial Port Reader also lets you redirect serial port output a file or the clipboard, so it is available for further analysis at any time.

This software utility allows you to read RS data from a designated port and monitor it even if another application had already opened it. Captured serial data can be displayed in various formats, and the opportunity of real-time monitoring is a great feature for problem resolution.

The received data can be saved to a file of your choice or copied to the clipboard. Sessions can be saved by Com Port Reader and can be reloaded if required. Multiple serial ports can be read simultaneously by this software tool. This feature is very useful when comparing data collected from different COM ports that are interacting with the same application within monitoring session.

In this case, all data is received and stored in a single log file on a first-in-first-out basis. Serial Port Reader allows you to choose the way that collected data is displayed on your computer. Four different view are available: table, line, dump, or terminal.

You have the option of monitoring all view modes at the same time. An option in terminal mode allows simulated data transmission from a serial application to a monitored COM port. The utility is fully compatible with these protocols, as well as those employed in RS, RS, and RS interfaces. Existing Members Sign in to your account. This email is in use.
