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.

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.

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.

In this post, we take a quick look at fixed-point numbers and how to use them in Rust. We also briefly explain why they are useful in embedded and other scenarios, with examples using the fixed crate.
