# scd40-rusty-pi
A Raspberry Pi Pico W implementation of a SCD40 based CO2 PPM monitor, it has a
web interface where the current values can be viewed. This is designed to work
with an I2C SCD40 module.
Please note that I am on about day 5 of learning Rust, so this code is not
provided with the intention of it being a correct example to follow. Comments
and feedback are welcomed! This is part of my own learning process.
***This is a work in progress.***
## Compiling - picoserve mod
I struggled to get `embassy` + `picoserve` to compile together using crates.io
sources. Despite the version number of `embassy` being the same it seems that
using the git sources fixes the problem (the issue is with
`embassy-time-driver`). But to achieve this I had to also edit the
`picoserve/Cargo.toml` in the `picoserve` project, which I have checked out and
sat alongside this project tree and referenced directly in this project's
`Cargo.toml`. Hopefully in time the issue with the crates.io compatibility will
be resolved.
