probe-rs-rtt

Host side implementation of the RTT (Real-Time Transfer) I/O protocol over probe-rs.

Documentation

RTT implements input and output to/from a microcontroller using in-memory ring buffers and memory polling. This enables debug logging from the microcontroller with minimal delays and no blocking, making it usable even in real-time applications where e.g. semihosting delays cannot be tolerated.

This crate enables you to read and write via RTT channels. It's also used as a building-block for probe-rs debugging tools.
