📡 Serial (USART) Frame Generator

🎯 Getting Started

This tool converts text into visual USART/UART bit-streams showing exactly what you'd see on an oscilloscope. Perfect for debugging serial communication and verifying register-level code.

📝 Input Text

• Type any text string (e.g., "Hello", "AT+CMD")
• Each character is transmitted as a separate frame
• See ASCII codes and binary representation for each character

⚙️ UART Configuration

• Baud Rate: Transmission speed (9600, 19200, 38400, 57600, 115200 bps)
• Data Bits: Number of data bits per frame (5, 6, 7, 8, or 9 bits)
• Parity: Error checking (None, Even, or Odd)
• Stop Bits: Frame termination (1, 1.5, or 2 bits)

📊 Visual Output

• Timing Diagram: Shows HIGH/LOW signal states over time
• Frame Structure: Clearly labels Start, Data, Parity, and Stop bits
• Bit Timing: Displays actual bit duration based on baud rate
• Hover Info: Hover over bits to see detailed timing information

💻 C Code Generator

• Generates register-level initialization code for AVR/Arduino
• Shows UBRR calculation for baud rate
• Includes frame format configuration (UCSRnC register)
• Ready to copy and paste into your embedded project
