[Ru]st [E]lectronic [D]atalogger - my explorations into an embedded, async, real-world project

This is heavily inspired by ruwm by ivmarkov.

If you have questions, find me on Discord in the #embedded channel or in #esp-rs on Matrix

With any IoT 'stack', there are some rudimentary basics; this repo is an attempt at building these out using the embedded_svc library and its family of crates from Espressif, such as esp-idf-svc, esp-idf-sys, and esp-idf-hal.

• Install rustup, preferrably in linux. Using an x86 CPU will help a great deal. Attempts on an Apple M1 Max failed terribly for me.
• Build your ESP toolchain by following: https://github.com/esp-rs/rust-build or even better use espup.
• Run cargo +esp build --release
• Use the following:

// flash
scp 10.0.3.70:~/esp/rued/partitions.csv . \
    && scp 10.0.3.70:~/esp/rued/target/xtensa-esp32-espidf/release/rued-esp32 . \
    && espflash flash --baud 920000 --monitor rued-esp32 --partition-table partitions.csv

// monitor for stack-traces
scp 10.0.3.70:~/esp/rued/target/xtensa-esp32-espidf/release/rued-esp32 . && espflash monitor --baud 115200 --elf rued-esp32
// You will need to restart the chip

Add the following to settings for rust-analyzer

{
    "rust-analyzer.server.extraEnv": {"LIBCLANG_PATH": "/home/mdesilva/.espressif/tools/xtensa-esp32-elf-clang/esp-15.0.0-20221014-x86_64-unknown-linux-gnu/esp-clang/lib/"},
}

espup install --esp-idf-version 5.0
export LIBCLANG_PATH=$HOME/.espressif/tools/xtensa-esp32-elf-clang/esp-15.0.0-20221014-x86_64-unknown-linux-gnu/esp-clang/lib/

# cd into your app root
cargo clean
rm -rf .embuild
cargo build --release

# check for `~/.espressif/esp-idf/release-v5.0`
