The Saleae Logic software supports decoding UART communications using the provided Async Serial Analyzer in the Logic software.
A UART (Universal Asynchronous Receiver/Transmitter) is a hardware block most commonly found in microcontrollers and processors. Its primary job is to send and receive asynchronous serial data to and from other UART devices via two data lines: TX and RX.
Typically, the serial data are organized in the following format:
The Async Serial Analyzer in the Logic software can be configured for various data sizes, stop bits, and parity settings. For details on setting this up, please see the article: Using the Async Serial Analyzer
