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 PIO Blink Using Logic Analyzer on Raspberry Pi Pico with Embedded Rust
In this post, we use a logic analyzer to study a GPIO signal generated by a PIO state machine on the RP2040. We derive the timing from instruction cycles and validate it on real hardware with Embedded Rust.
