Auto-generated wrappers around registers for AVR microcontrollers.
Add the following to Cargo.toml:
toml
[dependencies.avr-device]
version = "0.5.1"
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 |
| atmega88p | | | | attiny85 |
| atmega168 | | | | attiny88 |
| atmega324pa | | | | attiny816 |
| atmega328p | | | | attiny841 |
| atmega328pb | | | | attiny861 |
| atmega32a | | | | |
| atmega1280 | | | | attiny1614 |
| atmega1284p | | | | attiny2313 |
| atmega128a | | | | attiny2313a |
| atmega128rfa1 | | | | attiny404 |
| atmega2560 | | | | |
| atmega164pa | | | | |
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 (= 0.3.3), svd2rust (= 0.28), form (>= 0.8), rustfmt(for the nightly toolchain) and svdtools (>= 0.1.9) installed:
bash
cargo install atdf2svd --version 0.3.3
cargo install svd2rust --version 0.28.0
cargo install form
rustup component add --toolchain nightly rustfmt
pip3 install --user svdtools
Next, clone this repo and build the device definitions: ```bash git clone https://github.com/Rahix/avr-device cd avr-device make
cargo +nightly doc --features
avr-device is generated using atdf2svd and 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/ (or avr-mcu/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"). 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. Ideally, try to reuse the exisiting patches in patch/common/ or patch/timer/.
Finally, try building the crate for your MCU with make <chipname>.
