Used in avr-device
Auto-generated wrappers around registers for AVR microcontrollers.
Add the following to
[dependencies.avr-device] version = "0.1.0" features = ["atmega32u4"]
Via the feature you can select which chip you want the register specifications for. The following list is what is currently supported:
The version on
crates.io is pre-built. The following is only necessary when trying to build this crate from source.
rustup component add --toolchain nightly rustfmt cargo install form cargo install svd2rust cargo install atdf2svd pip3 install --user pyyaml
Next, clone this repo and build the device definitions:
git clone https://github.com/Rahix/avr-device cd avr-device make # You can build for just one specific chip using # make atmega32u4 # I suggest building documentation as well cargo +nightly doc --features <chip> --open
avr-device is generated using
svd2rust. The vendor-provided atdf files can be found in
vendor/. The intermediate svd files are patched by
svdpatch.py (Adapted from
svdpatch.py in stm32-rs) with device-dependent patches in
patch/, mainly to improve undescriptive names and missing descriptions.
To add a new chip, download the atdf from http://packs.download.atmel.com/ and place it in
vendor/. Be sure to name it like the Rust module that should be generated. Next, you need to integrate it into the base crate and build system. Follow what was done in commit 290613454fbd ("Add basic support for ATmega64"). Please adhere to the alphabetical sorting that is present so far.
If patches need to be applied, create a
patch/. The patching format is compatible to the YAML patching format of stm32, except that you do not need to provide the path to the svd file (
_svd: ...) since it is generated in the build process. Additionally, the following patching was added:
PERIPHERIAL: REGISTER: _modify: FIELD: # If a field already contains a write-constraint, you can # change it using the _write_constraint modifier. The # following values are allowed: # "enum": Only allow enumerated values (<useEnumeratedValues>) _write_constraint: "enum" # Remove any existing writeConstraint tag _write_constraint: "none" # Constrain to a range of values (<range>) _write_constraint: [min, max] FIELD: # Replaces the enumeratedValues definition for this field. # If it does not exist yet, it is created. _replace_enum: NAME: [VALUE, DESCRIPTION]
