weensy.rs
A collection of useful bits and bobs for programming the Teensy 4.1 microcontroller using Rust.
NOTE:
This package is meant to be used as an extension of teensy4-bsp
.
It is strongly recommended that you familiarize yourself with that library's API before using this package.
USAGE
This package should be used by an executable crate targetting the Teensy 4.1. The following configuration of cargo
is required to build your executable properly:
[build]
target = "thumbv7em-none-eabihf"
[target.thumbv7em-none-eabihf]
rustflags = ["-C", "link-arg=-Tt4link.x"]
This code should be placed in <CRATE_ROOT>/.cargo/config.toml
. It can also be passed directly to the cargo
command
using CLI flags, but this is not recommended because it's clunky.
See cargo
's documentation for more details. The t4link.x
file will be generated by teensy4-bsp
's
build.rs
file. teensy4-bsp
is included by this
package, and thus the build script will run when building any crate importing this package. All feature flags for this package's dependencies are re-exported, and enables teensy4-bsp
's rt
feature by default.
Once this is done, cargo install
cargo-binutils
and
then run the following in the root directory of your executable crate:
cargo objcopy --release -- -o ihex out.hex
You can then flash out.hex
to your Teensy board using the
Teensy's provided tools.
