04:52 <djdisodo[m]> error messages fill up memory

04:53 <djdisodo[m]> is there a way i can just print some kind of code from microcontroller and compare that code with dictionary to check error message

05:02 <M9names[m]> sure! that's what defmt does internally, if you don't mind the dictionary being in your elf file defmt's a good option

05:10 <M9names[m]> this is obviously not exclusive to defmt though - I watched a talk from an intel engineer (can't remember which one) for C firmware where they write out all the error messages including formatting string in some format, and use codegen to get the impl in code for packing the string index and the data, as well as generating the tool for decoding this data.

05:10 <M9names[m]> if you just want prebaked strings with no data you can do a simple index lookup instead, but usually for debugging you want some runtime values as well.

07:47 <sourcebox[m]> ryan-summers: What do you think about having a dummy UsbBus implementation in usb-device? This would allow to make example that actually build. E.g. the usbd-serial readme example would just need `usb_bus` to be assigned to such a dummy bus instance to compile.

07:52 <zachariasfrings[> Hello, i want to program my raspberry pico with rust. I am looking and two different options. rp-hal (https://github.com/rp-rs/rp-hal) and embassy. What exactly is the difference between the two and which one should I use for a small Uni-Project?

08:42 <badyjoke[m]> <zachariasfrings[> "Hello, i want to program my..." <- AFAIK, the main difference is that embassy will let you do multitasking using async/await. It depends if you want to have multitasking for you project . If I remember correctly you can use embassy-rp without using asyn/await. dirbaio Will have agreater knowledge than me.

08:48 <badyjoke[m]> Oh and rp-rs has a BSP for the raspberry pico, if you want something to use directly without going throught configurations

09:13 <M9names[m]> I would not choose one over the other based solely on BSP availability

09:14 <M9names[m]> the BSP does not provide much for Pico, anyway - there's not much on the board!

09:20 <dirbaio[m]> the led 😎

09:20 <M9names[m]> yeah, and the flash chip

09:21 <dirbaio[m]> yeah the bsp basically renames "PIN_25" to "LED" :P

09:21 <M9names[m]> if it's a Pico W the answer is easy - use embassy-rp. rp2040-hal has no support for the wifi chip, which means it also can't blink the LED on board.

09:21 <M9names[m]> if you want to use async, use embassy-rp.

09:22 <M9names[m]> otherwise... you can totally get the job done with either. but i think given you've already expressed a dislike for boilerplate you'll probably hate the generics in rp2040-hal

09:22 <M9names[m]> so, uh, try embassy-rp first and switch if you decide you hate it?

12:55 <Mathias[m]> For people at Oxidize Conference (or in Berlin), let's meet at 7 PM outside the venue for a Rust Embedded social.

14:20 <PinballWIzard[m]> Am I right? I am interested in using COBS in case....

14:20 <PinballWIzard[m]> Hi jamesmunns dropping a question here about using UART with postcard-rpc: you told that there's no way atm to use the nice dispatch macro, but I could compose my dispatcher also with UART also with :

14:20 <PinballWIzard[m]> https://docs.rs/postcard-rpc/0.5.0/postcard_rpc/struct.Dispatch.html#method.add_handler

15:54 <sirhcel[m]> Anyone interested in eating out and having a beer later near oxidize conf? Meet Mathias and me at the conference drink. 🍻

17:53 <JamesMunns[m]1> <PinballWIzard[m]> "Hi jamesmunns dropping a..." <- Yeah, the name is confusing, that's the "old" dispatcher, if you aren't using async it should work well, but won't work very well for async.

18:15 <embassy-learner[> <JamesMunns[m]1> "Yeah, the name is confusing..." <- Hi @jamesmunns:beeper.com thanks first of all! I am still pinball_wizard this will be my matrix account the other one was a quick one now trashed......
