A serial port interface is a Graphical User Interface program that runs on a computer and can be used to connect to the devices with a microcontroller and the same hardware device.
In this article, I am going to describe this step by step with a screenshot and source code.
Prerequisites
- Visual Studio IDE to develop the code
- System with Serial Port communication (comport or USB) for transmitting and receiving the data.
- Terminal software for testing.
Code and explanation
- The above screenshot is the user interface for Serial Communication
- The first combobox is used to select the com ports from the available ports and the Connect button is used to establish the local machine into the hardware via a communication cable.
- Transmit data textbox area is to enter what we have to transmit, and a send button is used to transmit the data.
- Receive textbox area for receiving the data from the receiver.
- Status textbox is used to display current application status to the user.
- For testing you can useTerminal software; it's freely available, and you can download it from the below link.
- The source code is attached here with comments. If you need any clarification please comment.
