07:04 <re_irc> <@hardikthecoder:matrix.org> hey

07:06 <re_irc> <@hardikthecoder:matrix.org> +is anyone Know Rust embedded open source project, I would like to contribute

07:08 <re_irc> <@hardikthecoder:matrix.org> hey

07:08 <re_irc> is anyone Know Rust embedded open source project, I would like to contribute

08:07 <re_irc> <@imdoor:ilgt.lv> hey, this isn't strictly rust related, but I wanted to get some opinions on how reliable is i2c bus sharing in practice. i've seen people complaining online about i2c bus lockups but how likely am i to run into such issues? if i have GPIO to spare, should i just wire everything separately, or would that just be unsubstantiated paranoia? it's for a hobby project, I need to talk to just a few sensors

08:19 <re_irc> <@mameluc:matrix.org> hardik sharma: super broad, start working on something that interests you. When you find something that needs fixing, do it. That will force you to understand the code fully

08:22 <re_irc> <@mameluc:matrix.org> : my 2cnt is that if your i2c bus locks up you are screwed anyway as your code will wait forever for it to finnish. Many mcus have multiple i2c peripherals, if you have i2c pins to spare, why not use them. For hobby projects there is no need to do the optimal thing. For production there is a chance your chip is too beefy if you have a lot of pins unused.

08:24 <re_irc> <@mameluc:matrix.org> As a learning opportunity you might want to limit yourself to one bus. Then you have to understand how to share it and how to make it work

08:24 <re_irc> <@hardikthecoder:matrix.org> : yeah I m interested in embedded

08:24 <re_irc> <@hardikthecoder:matrix.org> I don't where to start

08:25 <re_irc> <@hardikthecoder:matrix.org> +know

08:26 <re_irc> <@hardikthecoder:matrix.org> I m curious in embedded

08:26 <re_irc> <@hardikthecoder:matrix.org> +system

08:26 <re_irc> <@mameluc:matrix.org> try getting a couple of dev boards from somewhere, get some leds to blink go from there

08:29 <re_irc> <@jannic:matrix.org> Perhaps build something you are interested in? Small robot? Some automation for your model railway? Automatic plant watering? Just chose something where you are sufficiently motivated to work on, but where no harm is done if you don't finish.

08:31 <re_irc> <@diondokter:matrix.org> I saw this video yesterday: https://www.youtube.com/watch?v=ZMQbHMgK2rw

08:31 <re_irc> Maybe some inspiration on what you could try :)

08:31 <re_irc> (Though probably start simple)

08:32 <re_irc> <@hardikthecoder:matrix.org> : thanks

08:33 <re_irc> <@mameluc:matrix.org> saw that video too. super interesting

08:36 <re_irc> <@mameluc:matrix.org> : something that keeps up your interest is a good way for keeping up the motivation 👍️

08:36 <re_irc> <@imdoor:ilgt.lv> hardik sharma: i've had good experience with the knurling sessions book, where you follow along to build a CO2 monitoring device https://session20q4.ferrous-systems.com/ it's somewhat expensive, though, to buy the parts you need, but a big plus for me, at least, was that you build something useful

12:34 <re_irc> <@hardikthecoder:matrix.org> : I m interested in Smart Home Security System

12:34 <re_irc> <@hardikthecoder:matrix.org> +actually

13:36 <re_irc> <@hardikthecoder:matrix.org> : thanks

15:02 <re_irc> features = ["defmt-log"]

15:02 <re_irc> default-features = false

15:02 <re_irc> in your cargo toml

15:03 <re_irc> <@jamesmunns:beeper.com> looks like "log" is the default, and you can't have both enabled: https://github.com/rust-embedded-community/embedded-sdmmc-rs/blob/develop/Cargo.toml#L23-L25

15:04 <re_irc> <@jamesmunns:beeper.com> Weird this error didn't fire?

15:05 <re_irc> <@tommygilligan:matrix.org> nevermind i think i accidentally have default feature active

15:22 <re_irc> <@tommygilligan:matrix.org> : ty!

15:53 <re_irc> <@tommygilligan:matrix.org> testing this just now with pico + https://core-electronics.com.au/sd-card-module.html

16:04 <re_irc> <@tommygilligan:matrix.org> works for me

16:33 <re_irc> <@thejpster:matrix.org> yes that is weird

19:03 <re_irc> <@shakencodes:matrix.org> Does anyone have recommendations for a (small, simple) GUI appropriate for an embedded system? We'll be driving an e-Ink display, so it doesn't need to be fancy.

19:04 <re_irc> <@diondokter:matrix.org> : Take a look at embedded-graphics. Never used it but I hear good things

19:11 <re_irc> <@dngrs:matrix.org> maybe also embedded-layout (https://github.com/bugadani/embedded-layout) or embedded-menu (https://github.com/bugadani/embedded-menu), both of which build on top of e-g

19:12 <re_irc> <@bugadani:matrix.org> embedded-layout is just a silly little "move this Drawable next to that Drawable" library, though it might be useful

19:12 <re_irc> <@bugadani:matrix.org> embedded-menu is very immature and binarycolor-only

19:13 <re_irc> <@jamesmunns:beeper.com> btw I'm working on breaking out the terminal emulator I showed off a while back (unit tests in lieu of docs): https://github.com/tosc-rs/teletype/blob/main/crates/input-mgr/tests/exemplar.rs

19:14 <re_irc> <@bugadani:matrix.org> : I'll be honest, I don't remember this at all

19:14 <re_irc> <@jamesmunns:beeper.com> More viewable demo of this engine, with embedded graphics and minifb on top of it: https://www.youtube.com/watch?v=_gmjmLKpk08

19:14 <re_irc> <@bugadani:matrix.org> : ah great, someone needed something like this a few days ago

19:16 <re_irc> <@jamesmunns:beeper.com> (it's going for a more "text/im chat bubble" take on a terminal emulator)

19:20 <re_irc> <@bugadani:matrix.org> : time to delete most of embedded-text then 🙃

19:37 <re_irc> <@jamesmunns:beeper.com> : Nah, this is one really specialized tool, and you should totally steal any bits that are useful to you :D

19:54 <re_irc> <@shakencodes:matrix.org> Thank you, everyone!
