Frame Format

UART transmitted data is organized into packets. Each packet contains 1 start bit, 5 to 9 data bits (depending on the UART), an optional parity bit (can be used to detect single bit errors), and 1 or 2 stop bits:

Decoding in HScope

  • Input range: at least 5V
  • Sampling rate: at least 100KSa/s for a baud rate up to 19200, 500KSa/s for 112500
  • Use the digital module to enable the decoding

Sample of HScope decoded data:
