01:33 <re_irc> <@y​atekii:m​atrix.org> nihal.pasham: https://github.com/probe-rs/probe-rs/pull/774 can you test this?

01:46 <re_irc> <@n​ihal.pasham:m​atrix.org> yatekii: will do (just woke up so might be a while)

01:47 <re_irc> <@y​atekii:m​atrix.org> no hurry, I should sleep since 4 hrs at least so yeah

01:47 <re_irc> <@y​atekii:m​atrix.org> will be back in 8 or so

04:43 <re_irc> <@n​ihal.pasham:m​atrix.org> yatekii: tested it. it works. added my results (and comments) to the PR

09:31 <re_irc> <@y​atekii:m​atrix.org> nihal.pasham: awesome, thanks!

11:15 <re_irc> <@l​uojia65:m​atrix.org> We are very happy to announce Tornado-os operating system kernel, after six months of development, has reached version 0.1 🥳

11:15 <re_irc> <@l​uojia65:m​atrix.org> This kernel is written in Rust, with async/await coroutine runtime used in kernel level, like drivers and file systems. The kernel provides async/await executor directly to user level.

11:15 <re_irc> <@l​uojia65:m​atrix.org> Please star our repository: https://github.com/HUST-OS/tornado-os

13:32 <re_irc> <@j​amesmunns:m​atrix.org> luojia65: could you please tweet about that (and mention `@rustembedded`)? I'd love to signal boost!

13:32 <re_irc> <@j​amesmunns:m​atrix.org> (also: congrats!)

13:37 <re_irc> <@n​ihal.pasham:m​atrix.org> luojia65: quick question - is `documentation` available in english?

15:00 <re_irc> <@y​atekii:m​atrix.org> Nice Faker is working on tonado-os :D

20:47 <re_irc> <@r​icharddodd:m​atrix.org> Quick question: EASY_DMA_SIZE was removed from embassy-nrf. What should I use instead?

21:38 <re_irc> <@d​irbaio:m​atrix.org> richarddodd: I think it was unintentional, when refactoring all chip-specific stuff into `chips/nrf52xxx.rs`. PRs welcome

21:38 <re_irc> <@d​irbaio:m​atrix.org> should be a simple `pub use chip::EASY_DMA_SIZE` or similar

21:39 <re_irc> <@r​icharddodd:m​atrix.org> I just did a different PR

22:11 <re_irc> <@r​icharddodd:m​atrix.org> I feel silly but i can't work out how to calculate softdevice RAM usage. Is there an easy way to work out how much RAM it will need with the default config?

22:36 <re_irc> <@r​icharddodd:m​atrix.org> Actually scrap that I'm getting `SdmIncorrectInterruptConfiguration`. Absolutely no idea why.

22:37 <re_irc> <@d​irbaio:m​atrix.org> there's no easy way to calculate RAM usage. If you give it too much / too little you'll get a warning/error saying exactly how much it needs

22:38 <re_irc> <@d​irbaio:m​atrix.org> `SdmIncorrectInterruptConfiguration` is when you have some interrupt enbled at a reserved priority level

22:38 <re_irc> <@d​irbaio:m​atrix.org> priorities 0, 1, 4 are reserved for the softdevice

22:39 <re_irc> <@d​irbaio:m​atrix.org> it may be interrupts managed by embassy-nrf, in which case make sure you have this https://github.com/embassy-rs/nrf-softdevice/blob/15d2549e63d491ef8c6fa8ab4385cedeb48fb496/examples/src/bin/ble_peripheral_onoff.rs#L128-L129

22:39 <re_irc> <@d​irbaio:m​atrix.org> or it may be interrupts you've enabled on your own, in whcih case make sure you set them to a non-reserved prio

22:47 <re_irc> <@r​icharddodd:m​atrix.org> Thanks I'll go through these. Don't know why I thought it was memory error - I probably need sleep.

22:48 <re_irc> <@r​icharddodd:m​atrix.org> Right it's probably the fact that I'm using `#[embassy::main]` rather than setting up the interrupts manually (with priority 2). I haven't check yet but sounds like that's what it is.

22:49 <re_irc> <@d​irbaio:m​atrix.org> ah yeah, default prio is 0 then

22:49 <re_irc> <@r​icharddodd:m​atrix.org> Thanks! :)

22:50 <re_irc> <@d​irbaio:m​atrix.org> you can still use a custom config with the main macro

22:50 <re_irc> <@d​irbaio:m​atrix.org> https://github.com/embassy-rs/embassy/blob/master/examples/stm32f4/src/bin/hello.rs#L23

22:53 <re_irc> <@r​icharddodd:m​atrix.org> yep changing irq prio fixed it :)

22:53 <re_irc> <@r​icharddodd:m​atrix.org> tbh writing it out manually isn't a problem - it's only a few lines of code and in exchange you get rid of macro magic

22:54 <re_irc> <@d​irbaio:m​atrix.org> yea.. macro magic is meh

22:55 <re_irc> <@r​icharddodd:m​atrix.org> Actually I can't talk - I spent a while [implementing a css parser as a proc macro](https://github.com/derekdreery/style)

22:56 <re_irc> <@d​irbaio:m​atrix.org> holy shit 🤣

22:57 <re_irc> <@r​icharddodd:m​atrix.org> I thought it worked well but it got exactly zero traction.

22:57 <re_irc> <@r​icharddodd:m​atrix.org> maybe the problem was the goal of the lib, rather than the quality

22:59 <re_irc> <@d​irbaio:m​atrix.org> fun.. it definitely seems useful for writing an SPA backed by rust+wasm... I've seen somewhere a similar macro for html-in-rust

23:01 <re_irc> <@r​icharddodd:m​atrix.org> (warning, this comment is OT and boring) the biggest problem I had was with how the lexer/tokenizer handled exponentials: most number can have arbitrary suffixes (so `2.0f32` is valid, and so is `2ff2cd`), but if you try to parse `2efc14`, say, then the lexer tries to parse an exponential (because of the `e`)...

23:01 <re_irc> ... and fails.

23:02 <re_irc> <@r​icharddodd:m​atrix.org> I was gonna have a go at refactoring the lexer, but it's a big job and I was already procrastinating from my actual work.

23:03 <re_irc> <@r​icharddodd:m​atrix.org> If you solved that problem, then you can have arbitrary alphanumeric sequences in your grammar and parse them from valid (to the tokeniser) rust source.

23:03 <re_irc> <@r​icharddodd:m​atrix.org> So hex colors, for instance, become possible

23:04 <re_irc> <@r​icharddodd:m​atrix.org> (the solution would be to push actually parsing the number past the point at which proc macros run)

23:22 <re_irc> <@h​armony:m​atrix.org> How tf do you pick a voltage regulator ic

23:22 <re_irc> <@h​armony:m​atrix.org> Need 3.7-4.2V to 3.3V with low energy loss ig

23:22 <re_irc> <@h​armony:m​atrix.org> OT:

23:22 <re_irc> <@h​armony:m​atrix.org> There are thousands
