UART Frame and Baud Diagnosis

Decode captured UART bytes and recognise voltage and baud-rate compatibility issues.

Guided setup

  1. Load the UART preset.nDecode the hexadecimal byte sequence.nChange baud rate and estimate frame time.nValidate board logic voltage before connecting a USB-UART adapter.

Expected observations

  • Hex bytes decode to readable text when valid.nAt 115200 baud, a typical 8N1 byte uses ten bit periods.nCommon ground and safe logic levels remain mandatory.
