 Mattias Grönlund | I have not seen the other ones, so I guess it is a new greenfield approach... | 19:57:06 |
| Mattias Grönlund | therealprof: Do you have any link to other approaches? | 19:58:36 |
 therealprof | Looking... | 19:58:53 |
| therealprof | https://github.com/HarkonenBade/cube-parse | 19:58:56 |
| Mattias Grönlund | Hmm, that one seems to try to provide some higher level interface, I have just tried to transform each available element/attribute to rust structs. Currently covering Mcu and IP documents, I am not sure if the other documents are of much interest. It seems like they mostly defines cubeMX API functions. | 20:02:25 |
 ra_kete | There is also currently a PR open for the stm32f3xx-hal that parses the CubeMX DB: https://github.com/stm32-rs/stm32f3xx-hal/pull/129 | 20:03:16 |
| ra_kete | Would be cool if that could use some other crate for the parsing instead of implementing that again | 20:03:42 |
| ra_kete | Especially for sharing between HALs | 20:03:54 |
| therealprof | Thanks, https://github.com/dbrgn/cube-parse was what I was looking for. | 20:04:43 |
| therealprof | I thought there was at least another one... | 20:04:57 |
| ra_kete | I think the F0 HAL also has one of these PRs open for a while | 20:05:32 |
| therealprof | Oh... | 20:06:14 |
| therealprof | Based on the same. | 20:07:18 |
| ra_kete | https://github.com/stm32-rs/stm32f0xx-hal/pull/29
But I was wrong, there is only relevant discussion there, no actual CubeMX parsing. And yes, that's also about cube-parse | 20:10:08 |
| ra_kete | cube-parse is pretty limited in what it does, it generates very specific GPIO mappings. I found it easier to write the parsing logic again than to fork it. But I have been thinking about librarifying the parsing, it just didn't fit into the experiment | 20:12:48 |
| Mattias Grönlund | Partly what I was after was to get the model/schema for the cubemx-db, to better understand what to expect to gain from it. | 20:14:42 |
| ra_kete | Maybe I'll have time to have a look at your crate and give some feedback this weekend. Sounds interesting :) | 20:15:54 |
| Mattias Grönlund | I had a quick look at pull/29 and realize that it generates code with the current macros. I have more and more started to believe that it would be better to generate code without any macros as that code is easier for the end user to work with... | 20:17:55 |
| Mattias Grönlund | Feedback is always welcome, I am just learning rust so I expect that things should be in some other way :-). | 20:19:10 |
| ra_kete | We definitely want to get away from the macros. But I wanted to introduce the GPIO features independently from a full-blown GPIO refactor, to keep the scope manageable. Once the GPIO gets refactored the codegen will change with it, but I'd like to ensure beforehand that the general idea actually works | 20:20:19 |
| Mattias Grönlund | I also think we should create some kind of stm32-hal which the different family-hal implementations could implement. Making it easier to share low level peripherals. | 20:20:57 |
| Mattias Grönlund | Yes, I got that feeling, and it is probably the right thing to do :-). | 20:21:38 |
| therealprof | In reply to @eldmgr:matrix.org
I also think we should create some kind of stm32-hal which the different family-hal implementations could implement. Making it easier to share low level peripherals. That's super-gnarly to do. But at least more and more projects are moving support for specific peripherals out of the hal impls with only a thin layer remaining. | 20:23:50 |
| Mattias Grönlund | I have tested to go quite a bit further with gpio on the macro path to have it work without any unsafe code, but my feeling is that it would be easier to do with code-generation from cubemx-db directly. | 20:27:42 |
| Mattias Grönlund | Yes it might be gnarly, but my hope was to find enough information in cubemx-db for it to work... So, I thought I should start and decode the cubemx-db to see what would be possible... | 20:30:40 |
| Mattias Grönlund | So, my next test will be to see if I can do some sort of code generation, as I said I am just starting to learn Rust. | 20:32:30 |
| therealprof | Every little bit helps! | 20:39:15 |
