avr-hal VS just

I found the generics a lot less of a problem when I realized I could parametrize on things like embedded_hal::serial::Write instead of UsartOps https://github.com/Rahix/avr-hal/pull/264/commits/17ed15321cb8fcf8aedb1f8133be1f189eb06a6f

I've come across avr-rust, avr-hal and both seem to have arduino stuff, wondering which is the most beginner friendly? (I have a bit of experience with the regular arduino IDE but want to switch over to doing all the stuff in rust for a challenge)

fyi, a minor follow-up at https://github.com/Rahix/avr-hal/issues/388

I have contributed a little to this. avr-hal I have done a couple little hobby projects with it as well, but I can't say it's the best thing out there.

All you need is in the documentation: https://rahix.github.io/avr-hal/arduino_hal/index.html even though reading the documentation without knowing what you're looking for can be quite difficult, so looking at some examples might be more helpful.

Rust language shares all advantages of efficient C++ code. With the rust community growing year after year, more and more people try using rust to program their Arduino boards. Consequently, the Arduino Rust ecosystem have significantly developed in the last couple of years. The Hardware Abstraction Layer for AVR microcontrollers avr-hal, Rudino library and ravedude CLI utility to make Rust development for AVR microcontrollers easier are just a few examples of the solid foundation developed so far.

Today I was toying with the arduino again, making an attached LED matrix print awesome messages better than it previously had. I wanted to use millis() found in the examples in the unsurpassed avr-hal crate, to orchestrate the duration it should show (part of) a character before moving on. But that is all besides the point. I made a few mistakes that coincidentally compiled and as such made me believe I was doing things right. (Perhaps I should note here that I am visually impaired so it is a bit easier for me to glance over smaller differences.)

There's a blink example in the repo for the avr-hal crate.

I'm trying to make an Arduino display text on an LCD using I2C (HD44780). So far, I've used arduino-hal from the avr-hal crate (github.com/Rahix/avr-hal) to program the Arduino, and I wonder if anyone happens to know of a library/crate which is compatible with it? So far I've only found ag-lcd which doesn't seem to work with I2C.

I don't like makefiles, but I've been enjoying justfiles: https://github.com/casey/just

I started using just [0] on my projects and have been very happy so far. It is very similar to make but focused on commands rather than build outputs.

Define your recipes and then you can compose them as needed.

Welp there is absolute chaos in that thread -- guess it's not an April Fools joke.

I wonder if relying on CI for anything other than provisioning machines is a mistake -- maybe we should have never moved from doing things from local scripts written in $LANGUAGE.

That said, I'm probably biased since I'm a massive fan of things like `make` and more appropriately for the current age, `just`[0]

> When a command has some cognitive requirements I create a script with some ${1:-default} values and I store them all in $PATH enabled local/bin

I would consider using just for this:

Your coworker's experience is more principled: Make is a mediocre tool for executing commands. It wasn't ever designed for that. Although it is pretty common to see what you are mentioning in projects because it doesn't require installing a dependency.

For a repo where an easy to install (single binary) dependency is a non-issue, consider using just. [1] You get `just -l` where you can see all the command available, the ability to use different languages, and overall simpler command writing.

This is fantastic, but I'd say that this solution is somewhat in response to this open issue from 2019:

https://github.com/casey/just/issues/429

I really wish just was included as a package in distributions.

So far, I didn't work on new features at all but on stabilizing the ground for further development: 1. CMake lists and modules were rewritten a lot, now managing builds and their configurations is much lesser pain. 2. Brought in Justfile for regular tasks, and it's great, no less. 3. Linters, formatters, analyzers for almost all the code (except for Janet for now, as because of it being a niche and young technology, it didn't get enough attention yet). 4. ECS stub. Now runtime class doesn't look like a god object. 5. Started writing unit tests which didn't happen with my personal projects before and maybe indicates how serious am I about this one :D 6. Some of previously hardcoded data has been moved to INI files. Now, if I release the game in 10 years, and in 10 more years some eccentric person decides to make a variant of it, it will be slightly simpler.

i've grown to like this for my personal projects. https://github.com/casey/just
