Hey Rustaceans! Got a question? Ask here! (27/2022)!
I dont want the files to waste a lot of space so i decided to resize them. For that i used the resize method from the "image" crate. Everything works fine, until i start to upload images above 5mb. Then the resize method starts to rotate the images. I think i narrowed it down to the resize function deleting any existing exif data inside the image file. That way the orientation flag is removed and the image is in its default position. I already tried to fix this, by saving the exif data before resizing and then rewriting it to the image file. The only library that i could find that supports writing (at least for png and jpeg) was this one: kamadax-exif. The problem is, that when i write the exif data (all the previous data or just the orientation data) the file gets corrupted. Now to my question: Can someone recommend a library that can resize images, that preserves the aspect ratio and does not delete the exif data? if not, does someone have an idea on how to resize the images differently? Or maybe there exists another exif data crate that i can use? I hope this question is understandable, thanks in advance :)

Announcing: ImageSieve, a tool to assist in sorting and archiving images and videos
I absolutely loved all the crates available that made my life very simple in many cases. I used (among others) the slint ui framework, kamadak-exif, img_hash, fast_image_resize and rawloader.

What are the scenarios where "Rewrite it in Rust" didn't meet your expectations or couldn't be successfully implemented?
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

not entirely new to rust, but very new to rust+arduino,.... eli5 the differences between these projects?
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

Rust and arduino?
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.

Learning Embedded rust
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.

Five simple steps to use any Arduino C++ library in a Rust project 🦀
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.

The coincidental typos compiled..
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.)

From arduino to rust via avr-hal
There's a blink example in the repo for the avr-hal crate.

Hey Rustaceans! Got a question? Ask here! (34/2022)!
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.
What are some alternatives?
