Rust Bucket

This repo contains my solutions to the InventrKits '30 days lost in space' Arduino lessons/game/project

To make things more interesting(hard) I will attempt to complete the course using Rust instead of C

Dev Log

20250122

• Assembled dip-switch circuit
• Added a switch-control function to manage the cabin light
• Test: the switch now controls the cabin light!
• Day 3 complete!
• Added a secret message to the onboard LED

20250121

• assembled LED circuit
• verified circuit with 5v input
• move source code out of the redundant rustbucket folder
• Discovery! the onboard LED is controlled from pin d13, and we can use it to drive our external LED as well.
• activated external LED! driven by pin d12.
• the onboard and external lights now blink in sequence, in the future, lets see about driving them asynchronously, or in parallel
• Refactor: Extracted the led control code into a function that can operate on any OutputPin
• Day 2 complete!
• Completed 3 exercise with partner

20250120

• Begin Day 2
• Assisted partner in building an LED circuit
• she successfully controlled the LED using her C code

20250119

• completed Day 1
• successfully flashed blinky lite Rust code, verified with partner.

• Add environment variables to the conda env:
  • ~/miniconda3/envs/rust-python/etc/conda/activate.d/rust.sh

    export CARGO_TARGET_X86_64_UNKNOWN_LINUX_GNU_LINKER=$HOME/miniconda3/envs/rust-python/bin/x86_64-conda-linux-gnu-cc

> cat ~/miniconda3/envs/rust-python/etc/conda/activate.d/env_vars.sh 
#export RUST_SRC_PATH=$HOME/miniconda3/envs/rust-python/lib/librust/src/rust/src
export CARGO_HOME=$HOME/miniconda3/envs/rust-python/
export RUSTUP_HOME=$HOME/miniconda3/envs/rust-python/.rustup

• Install rustup in the conda env
• use custom install options
• check the install paths are in the conda environment

  default host triple: x86_64-unknown-linux-gnu
  default toolchain: nightly
  profile: default
  modify PATH variable: no

> curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | bash -s -- --no-modify-path --default-toolchain nightly --profile default

• Install ravedude: cargo install ravedude

• sudo usermod -aG dialout $USER

• test flash the board: `ravedude /dev/ttyACM0 target/avr-atmega328p/release/rustbucket.elf

• attempts to flash using ravedude failed with error 'board not found'

• flash using avrdude was successful: avrdude -p atmega328p -c arduino -P /dev/ttyACM0 -U flash:w:target/avr-atmega328p/release/rustbucket.elf:e

• Setup IDE. I preffer to setup dev dependencies in isolated Conda environments, however, Rust makes this fairly difficult, and I may be forced to use system-level Rust for now :(
• Following A complete guide to running Rust on Arduino
• Install the AVR toolchain system dependencies sudo apt install avr-libc gcc-avr pkg-config avrdude libudev-dev build-essential, not available in conda, may need to install an updated avrdude using conda if apt is out of date worry about isolated dev env later.
• Instructions for adding the Arduino target rustup target add avr-unknown-gnu-atmega328 fails
• avrdude is a cargo-generate template for avr-hal projects.
• A Hardware Abstraction Layer (HAL) is required to run Rust on AVR microcontrollers and other common boards.
• stable does not support the Arduino hardware target: rustup toolchain install nightly
• cargo install ravedude
• cargo install cargo-generate
• In the interest of getting this rust bucket up and running asap, we will use cargo-generate as advised... hopefully it will not make too much of a mess.
• cargo generate --git https://github.com/LundyBernard/avr-hal-template
• This generated a new file in the working directory, rustbucket/rustbucket/... i'll deal with it for now, as I may need multiple sub-projects
