Analyzing UART Signals in Embedded Rust Using a Cheap USB Logic Analyzer
In this post, we analyze UART signals from an embedded Rust project using a cheap USB logic analyzer and PulseView. We capture UART data, look at the raw signal on the wire, and use protocol decoding to understand how bytes are transmitted.
How to Use a Logic Analyzer in Embedded Rust Projects
In this post, we take a practical look at using a logic analyzer when working on embedded Rust projects. We cover what a logic analyzer does, how to interpret captured signals, and how it can be used to debug common protocols like I2C, SPI, and UART.
