UART Terminal Pro

Türkçe • English

A modern UART communication application built for embedded system development and test automation.

C# • .NET Framework 4.8 • Windows Forms

---

✨ Features

• Serial connection management — auto-detects and sorts COM ports; connect/disconnect with one click.
• Full configuration — Baud rate, Data Bits, Parity, Stop Bits selection.
• Colored terminal — incoming [RX] in green, outgoing [TX] in blue, [WAIT] in gold.
• Timestamps — optional HH:mm:ss.fff time prefix on each line.
• HEX / ASCII mode — view incoming data as readable text or hexadecimal.
• Line-based command sending — type multiple lines and send them all in sequence.
• WAIT command — insert millisecond delays between commands (simple scripting).
• HEX sending — send a command as a hexadecimal byte array.
• Periodic sending — automatically resend commands at a defined interval (ms).
• Live counters — RX message, TX message and error counts.
• Auto scroll — terminal follows new data to the bottom (toggleable).
• Log saving — export terminal content to .txt / .log in UTF-8.
• Dark theme — eye-friendly navy/blue interface.

🧩 Requirements

• Windows (7/10/11)
• .NET Framework 4.8 runtime
• To build: Visual Studio 2019/2022 (or .NET Framework 4.8 build tools with MSBuild)

🚀 Installation & Running

Run prebuilt

1. Build the project or download the shared release.
2. Run UARTTerminalPro.exe from the bin\Debug\ (or bin\Release\) folder.

Build from source

# With Visual Studio
Open UARTTerminalPro.sln → Build → Run (F5)

# Or with MSBuild
msbuild UARTTerminalPro.csproj /p:Configuration=Release

📖 Usage

1. Connection

1. Plug the device into your computer; the app lists COM ports automatically on startup.
2. Select COM Port, Baud rate, Data Bits, Parity, Stop Bits.
   • Defaults: 115200, 8, None, One.
3. Click Bağlan (Connect). The status indicator turns green ● Bağlı (Connected).
   • Click again to disconnect (● Bağlı Değil / Not Connected, red).

2. Sending Data

• Type your command in the VERİ GÖNDER (Send Data) box and press ➤ GÖNDER (Send).
• If you enter multiple lines, each line is sent sequentially as a separate command.
• When HEX Gönder (Send HEX) is checked, the command is interpreted as hexadecimal (e.g. 48656C6C6F).
  • Format: a hex string with no spaces and an even number of characters.

3. Delays with WAIT

To insert a wait between command lines:

WAIT 500

This line waits 500 ms before sending the next command. It appears in the terminal as [WAIT] 500 ms.

Example send sequence:

AT
WAIT 1000
AT+VERSION
WAIT 500
AT+RESET

4. Periodic Sending

1. Enter the interval in the Periyot (ms) (Period) field (adjustable with the arrows).
2. Check Periyodik Gönder (Periodic Send) → the command(s) in the box are sent automatically at that interval.
3. Unchecking it stops the sending.

5. Terminal Options

Option	Description
Timestamp	Adds a time prefix to each line.
Auto Scroll	Automatically scrolls to the bottom as new data arrives.
HEX Mode	Displays incoming data as hexadecimal.

6. Other Buttons

Button	Function
TERMİNALİ TEMİZLE (Clear Terminal)	Clears the terminal and resets counters.
LOG KAYDET (Save Log)	Saves terminal content to a .txt / .log file.
YAZIYI KOPYALA (Copy Text)	Copy terminal text (present in the interface).

🔧 Technical Details

• Language / Framework: C#, .NET Framework 4.8, Windows Forms (WinExe).
• Serial communication: System.IO.Ports.SerialPort.
• Data reception: the DataReceived event fires on a background thread; the UI is updated thread-safely via Invoke.
• Sending: line by line with async/await; the WAIT command uses Task.Delay.
• Periodic sending: via System.Windows.Forms.Timer.
• Log format: UTF-8, default file name UART_Log_yyyyMMdd_HHmmss.txt.

---

📝 Notes

• The error counter is shown in the UI; it can be wired to error-handling logic in future versions.
• Connection errors are caught silently; the app does not crash on invalid port/parameter selection.
• HEX sending expects a valid hex string (no spaces, even length).
