avr-device [](https://crates.io/crates/avr-device) [](https://docs.rs/avr-device)  ========== Auto-generated wrappers around registers for AVR microcontrollers. ## Usage Add the following to `Cargo.toml`: ```toml [dependencies.avr-device] version = "0.3.4" features = ["atmega32u4"] ``` Via the feature you can select which chip you want the register specifications for. The following list is what is currently supported: | ATmega | ATmega USB | ATmega 0,1 Series | AT90 | ATtiny | |:---------------:|:------------:|:-----------------:|:-------------:|:-------------:| | `atmega8` | `atmega8u2` | `atmega4809` | `at90usb1286` | `attiny13a` | | `atmega48p` | `atmega32u4` | | | `attiny167` | | `atmega64` | | | | `attiny202` | | `atmega644` | | | | `attiny84` | | `atmega168` | | | | `attiny85` | | `atmega328p` | | | | `attiny88` | | `atmega328pb` | | | | `attiny816` | | `atmega1280` | | | | `attiny841` | | `atmega1284p` | | | | `attiny861` | | `atmega128rfa1` | | | | `attiny1614`| | `atmega2560` | | | | `attiny2313`| | `atmega164pa` | | | | `attiny2313a`| ## Build Instructions The version on `crates.io` is pre-built. The following is only necessary when trying to build this crate from source. You need to have [atdf2svd][] (= 0.3.1), [svd2rust][] (= 0.19), [form][] (>= 0.8), [rustfmt][](for the *nightly* toolchain) and [svdtools][] (>= 0.1.9) installed: ```bash cargo install atdf2svd --version 0.3.1 cargo install svd2rust --version 0.19.0 cargo install form rustup component add --toolchain nightly rustfmt pip3 install --user svdtools ``` [atdf2svd]: https://github.com/Rahix/atdf2svd [svd2rust]: https://github.com/rust-embedded/svd2rust [form]: https://github.com/djmcgill/form [rustfmt]: https://github.com/rust-lang/rustfmt [svdtools]: https://github.com/stm32-rs/svdtools Next, clone this repo and build the device definitions: ```bash 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 ``` ## Internals *avr-device* is generated using [`atdf2svd`](https://github.com/Rahix/atdf2svd) and [`svd2rust`](https://github.com/rust-embedded/svd2rust). The vendor-provided *atdf* files can be found in `vendor/`. The intermediate svd files are patched by `svdpatch.py` (Adapted from [`svdpatch.py`](https://github.com/stm32-rs/stm32-rs/blob/master/scripts/svdpatch.py) in [stm32-rs](https://github.com/stm32-rs/stm32-rs)) with device-dependent patches in `patch/`, mainly to improve undescriptive names and missing descriptions. ### Adding a new Chip To add a new chip, download the *atdf* from <http://packs.download.atmel.com/> (or [avr-mcu/packs/](https://github.com/avr-rust/avr-mcu/tree/master/packs)) 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")](https://github.com/Rahix/avr-device/commit/290613454fbdc5e4ac98e53deccaf74dafc88963). Please adhere to the alphabetical sorting that is present so far. Next, you **must** create a `<chipname>.yaml` in `patch/` which has at least the following content: ```yaml _svd: ../svd/<chipname>.svd ``` If more patches need to be applied (most likely!), they should be added into this file as well. The patching format is documented in the [`svdtools` README](https://github.com/stm32-rs/svdtools#device-and-peripheral-yaml-format). Ideally, try to reuse the exisiting patches in `patch/common/` or `patch/timer/`. Finally, try building the crate for your MCU with `make <chipname>`. ## License *avr-device* is licensed under either of * Apache License, Version 2.0 ([LICENSE-APACHE](LICENSE-APACHE) or http://www.apache.org/licenses/LICENSE-2.0) * MIT license ([LICENSE-MIT](LICENSE-MIT) or http://opensource.org/licenses/MIT) at your option.
