defmt
defmt
("de format", short for "deferred formatting") is a highly efficient logging framework that targets resource-constrained devices, like microcontrollers.
For more details about the framework check the book at https://defmt.ferrous-systems.com.
The git version of the defmt book can be viewed at https://defmt-next.ferrous-systems.com/.
Setup
New project
The fastest way to get started with defmt
is to use our app-template to set up a new Cortex-M embedded project.
Existing project
To include defmt
in your existing project, follow our Application Setup guide.
MSRV
The minimum supported Rust version is 1.76 (or Ferrocene 24.05). defmt
is tested against the latest stable Rust version and the MSRV.
Support
defmt
is part of the Knurling project, Ferrous Systems' effort at
improving tooling used to develop for embedded systems.
