Frequently Asked Questions

How are UART bits decoded from asynchronous transitions?

The decoder samples the signal line at half-bit intervals following each high-to-low start bit, reading 8 data bits (least significant bit first), and checking the high stop bit.

Does this tool handle parity bits?

Yes. The standard 8N1 configuration (8 data bits, no parity, 1 stop bit) is default, with support for even and odd parity checking.
