13:45 <emmanuelsearch[m> Barging in with job offers 😀 Several positions opened today at Inria to develop embedded Rust building blocks for the RIOT operating system code base. More info [here](https://recrutement.inria.fr/public/classic/en/offres/2023-07034).

14:28 <AdamHott[m]> Wondering if anyone could take a look at this main.rs of 27 lines. I included the problem description in the README.md and there are pictures in references -> images folder.

14:28 <AdamHott[m]> https://github.com/CodingInGreen/microbit_bb_red_led/blob/master/README.md

14:28 <AdamHott[m]> https://github.com/CodingInGreen/microbit_bb_red_led/blob/master/src/main.rs

14:28 <Lumpio-> The links are 404 so either they're wrong or it's a private repo

14:29 <AdamHott[m]> oh thanks I'll make it public now!

14:29 <AdamHott[m]> ok it's public now!

14:34 <Lumpio-> My guess is that the pin is wrong - the pin numbers on many popular microcontroller boards don't necessarily correspond to the hardware pin numbers because whoever made them thought that would be simpler

14:35 <AdamHott[m]> Do you think I should just plug through all of the pins other than the 3V and 0Vs for that connection?

14:35 <Lumpio-> Try p0_02

14:35 <AdamHott[m]> In the code? or on the Edge Connector? or both?

14:35 <Lumpio-> In the code

14:36 <Lumpio-> I think p0_02 might correspond to the pin labeled "1" on that breakout according to this picture: https://images.elecfreaks.com/mageplaza/blog/post/uploads/2017/11/5-1.jpg

14:36 <AdamHott[m]> Ooh wow this is super helpful. Is that for the micro:bit V2?

14:39 <Lumpio-> I think this might be for V1, it doesn't say

14:39 <Lumpio-> https://tech.microbit.org/hardware/edgeconnector/#pins-and-signals this is probably a more official list

14:39 <Lumpio-> So I guess for V2 it might be p0_03?

14:40 <Lumpio-> If you click "V2" the table should show the hardware pin names under "MCU" and the breakout pin numbers under "s/w"

14:41 <AdamHott[m]> Ah yes!

14:41 <AdamHott[m]> This makes sense!

14:41 <Lumpio-> Looks like they totally rearranged the pins between versions for some reason

14:41 <AdamHott[m]> Yeah, must have been added functionality

14:43 <AdamHott[m]> Hey thanks so much for your help!

14:44 <Lumpio-> Did you get it to work?

14:45 <AdamHott[m]> I'll have to clear the table and reconnect! Will take but a sprig of a moment.

14:46 <Lumpio-> Well, good luck!

14:46 <AdamHott[m]> THANK YOU!

14:57 <AdamHott[m]> <Lumpio-> "Well, good luck!" <- It works! Yayy!

15:05 <Lumpio-> Nice!

15:07 <Lumpio-> You'll find that the same pin can sometimes have 3 or more numbering schemes - one based on hardware port numbers, one based on physical chip pin numbers, and one based on whatever connector or board you're using

15:07 <Lumpio-> Can get confusing at times

15:17 <AdamHott[m]> How do you sort through that, just trial and error?

16:22 <Lumpio[m]> Adam Hott With documentation - like the table I linked, chip datasheets and sometimes even schematics

16:22 <Lumpio[m]> Sometimes people will unfortunately just talk about "pin 3" and then you'll have to make an educated guess as to which numbering it is.

16:29 <JamesMunns[m]> <AdamHott[m]> "How do you sort through that..." <- Yeah, when possible, it's usually worth checking the schematics to see. Different docs tend to use different conventions

16:31 <Lumpio[m]> There's also "board support packages" or BSPs available for some boards that define names for the pins and have predefined configuration for some onboard peripherals

19:34 <AdamHott[m]> Thanks Lumpio and James Munns! Earlier there was a call for blog posts, I wrote this up on github, wondering if anyone would care to review? https://github.com/CodingInGreen/microbit_v2_red_led

21:51 <chxry[m]> Is it possible to use defmt-serial and usbd-serial together?

22:53 <StephenD[m]> dfu on windows is impossible. I guess I will only support linux

23:07 <sourcebox[m]> <StephenD[m]> "dfu on windows is impossible..." <- What are you trying to do? I've written a tool that allows to flash via DFU on Windows. https://github.com/sourcebox/dfu-buddy

23:08 <sourcebox[m]> But yes, Windows needs to have the drivers from ST installed.

23:09 <StephenD[m]> I'm using the libusb driver, and it shows up now but writing to it causes a libusb access error

23:09 <StephenD[m]> Should I just bite the bullet and get the ST drivers?

23:09 <sourcebox[m]> StephenD[m]: What tools are you using?

23:10 <sourcebox[m]> dfu-util?

23:10 <StephenD[m]> Sorry, power just went out. Super stormy here

23:10 <StephenD[m]> I will get back to you later though!

23:11 <sourcebox[m]> Will not be here anymore because it's already after midnight here.
