UART Communication Between ESP32 and Raspberry Pi Pico in Rust
Learn how to connect a Raspberry Pi Pico to an ESP32 using UART with Embedded Rust. Configure serial communication, wire the boards correctly, and exchange data between the two microcontrollers.
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.
