00:43 <re_irc> <yruama_lairba> directly passing multipliers/dividers is much nicer, but you may loose portability

00:44 <re_irc> <yruama_lairba> i saw a "require" method on stm32f4xx that panics if the actual frequncy doesn't match

00:44 <re_irc> <dirbaio> stm32-rs hals for different families are so different there's not much portability anyway 🤣

00:46 <re_irc> <yruama_lairba> dibaio, you may have difference in clock setup across the same family

00:46 <re_irc> <dirbaio> within a single familiy rcc is (almost) always the same

00:46 <re_irc> <Lachlan Sneff> Require would be nice, better if that’s the default

00:47 <re_irc> <yruama_lairba> on F4xx families, there is big difference for the I2s clock generation

00:48 <re_irc> <yruama_lairba> for rcc clock, i always wonder if it is necessary to "freeze" clock

00:51 <re_irc> <yruama_lairba> for example, for i2s again, it would be nice for some advanced application to "own" the i2s clock tree to have a wider choice of sampling frequency

00:53 <re_irc> <yruama_lairba> but there not even yet a working hal for i2s :p

00:53 <re_irc> <yruama_lairba> need to go, bye

10:02 <re_irc> <thejpster> I had a productive few days stuck in my room due to COVID-19: https://twitter.com/therealjpster/status/1516131936586145795?s=20&t=PmwPcEwNtno9dBDgISamiw

10:03 <re_irc> <thejpster> Had to cache the glyphs to get 60 FPS though. And I can't work out how to re-colour a texture on the fly, so I actually cache 16 copies of each glyph - one for each foreground colour.

11:04 <re_irc> <James Munns> Hah! I think indirectly COVID has been a boon to Rust OS development

11:04 <re_irc> <James Munns> MnemOS got imagined while I was actively sick, and written while I was recovering, and I know Eliza put in a bunch of work on Mycelium under the same conditions

16:26 <re_irc> <Radu> Hello, as Rust is good for system programming, what kind of personal projects can I make as a beginner? Do you have any ideeas/recomandations?

16:27 <re_irc> <Radu> * ideeas/recommendations?

16:28 <re_irc> <Radu> -kind of

16:28 <re_irc> <K900> Blinking a LED is the usual starting point

16:28 <re_irc> <K900> From there, really just look at what is available and seems fun to you

16:32 <re_irc> <Radu> Thank you

16:32 <re_irc> <ryan-summers> blinky LED is the hello world of embedded - highly recommended

16:40 <re_irc> <Radu> Good to know it, fortunately, rust has a lot of books and resources to learn. I didn't enter very deep in embedded but as I understand, you can design your own boards, with your chip and components and then write code for it. Right?

16:41 <re_irc> <marmrt> That's how it goes

16:41 <re_irc> <newam> Radu: Yeah, there's nothing rust-specific about the hardware. Anything ARM Cortex-M or RISC-V based that runs C can run rust too.

17:00 <re_irc> <Radu> Do you have any resources to learn about those types of chips: cortex,msp430, RISC-V

17:16 <re_irc> <Lachlan Sneff> The CAN bus is working, thank you everyone!

17:17 <re_irc> <Lachlan Sneff> There's something weird going on with specifying the clock tree configuration directly though. The PLLMUL in the clock config gets 2 added to it within the HAL, so in mxcube you'd specify 9, but in stm32f1, you specify 7

17:20 <re_irc> <burrbull> Lachlan Sneff: Open issue, please

17:20 <re_irc> <Lachlan Sneff> Will do
