PC Terminal Program with C# Source Code

[Len_CONSULTRON]

Here is the C# source code to a terminal program for a Windows PC.

Minimum System Requirements:

• Windows 7.  A lower version may work but has not been tested.
• C# Compiler.  I have compiled this on both Visual C# 2017 and 2019.

This code started as a simple PSoC UART (remote) to PC terminal application to replace Teraterm, Termite, RealTerm, etc.

I did this to eventually enhance the UART comm capabilities to include features such as

• Data logging (appending to a .csv file)
• Data Plotting.  This includes saving the plots as a .png file or .csv.

This code has those features built in by using my packetizing protocol.

You are allowed to use this source code “at-will” for commercial or non-commercial purposes. I DO NOT state or imply any warranty for the use of this code in-whole or in-part.

I've attached an archive of the source code and a .pdf that describes the use and the packetizing protocol.

Dear @Len_CONSULTRON , thanks for nice work. Can you also provide BIN for test purpose, maybe in separate ZIP ?

Best Regards

ravo,

Try this.

Dear @Len_CONSULTRON ,

thanks for sending compiled program.

Radim,

This archive comes from the VSS 2019 publishing option.

Theoretically, it should contain everything needed to install the project binary on your PC.  Theoretically ...

I have not tested this on another PC that does not have my setup.

Please verify that this works OK for you.

Dear @Len_CONSULTRON 

i just tried to test the app, but I am not able to view or modify COM port settings (baudrate, parity etc..) . Are there some dialog with these settings ?

ravo,

You are correct.  The UART comm of 115200 baud 8N1 is "hard-coded" in the program.  This is the most common mode that I use it therefore I did not see the need to have a means to change it.   The data rate is fast but not too fast.

However, it can be changed by modifying the source code.  Very easy to do!

Dear @Len_CONSULTRON ,

thanks for response and confirmation. I also use this baudrate for ddebug & testing purpose. But for industrial application i use preferably 19200 with some kind of CRC due harsh (noisy) environment.

Best Regards

ravo,

Microsoft offers a version of their development IDE free.  (Consult Microsoft for commercial use limitations of the use of this product.)

Right now, Visual Studio 2022 is available for free download.

If you download and install this product and download the Terminal source code I provide, you should be EASILY able to change it.

Double-click on the Uart.sln.  It will launch the version of Visual Studio you installed.

Look for "Uart/Properties/Settings/Serial_Baudrate". (Shown in the RED boxes below.)

Here you can easily change it to the desired baud rate you want to support.  Note:  in this version of "Uart" the protocol "8N1" is also hard-coded but can be changed by further changes in the program.

As for CRC ... that's a bit more difficult.

The "Uart" terminal program was designed for "simple" Uart communication (ie Baudrate @  8N1).  It assumes non-packetized serial communication but rather a byte-by-byte character passing of information between the target terminal device and the PC.

A CRC-based protocol basically requires that the data be packetized.  This is definitely possible.  In fact, I support my own proprietary packetized protocol in Uart for passing data streams and for plotting.  However, it doesn't support CRC verification.  It could but doesn't.

You can use this source code as a launching point to add packetized/CRC validated data.   I do recommend that you first compile and run the code "as-is".  This proves that your design environment is configured properly.  Then you can modify the code with confidence.
