Re: Custom apps outside the tree
There is an inexistent, ignored entry in apps called external. By creating a symlink called external you should end up with no, as you called "poop". I assume that you mean no extra files or modifications in NuttX repositories.

Re: Touchscreen scaling/LVGL
Maybe additional IOCTL in touch display drivers, for example here https://github.com/apache/nuttx/blob/master/drivers/input/ads7843e.c#L943 Two calls, one accepting calibration matrix, and another to remove it and come back to raw readings. In typical Linux there is an `xinput` command to do it https://wiki.archlinux.org/title/Calibrating_Touchscreen#Apply_the_Matrix. Am Di., 23. Mai 2023 um 20:37 Uhr schrieb Alan C.

Re: Touchscreen scaling/LVGL
It would be great if NuttX would offer calibration of touch screens out of the box. I am not sure where it should go, but I think it could be a wrapper that is used by many drivers. I think we have a similar situation with flash filesystems. There are multiple layers that stack on each other. For example here there is `ftl_initialize` (flash translation layer) and then `smart_initialize` (filesystem) https://github.com/apache/nuttx/blob/master/boards/arm/stm32/stm32f103-minimum/src/stm32_w25.c#L266 Regarding the calibration itself, you probably know how to implement it, but otherwise you might find this useful https://gitlab.com/nxtlabs/shared-libs/touch-calib-lib/-/wikis/home (explanation and implementation) Coming back to your question, how do other people do it? For me it was just user-space code, part of the application. Am Di., 23.

Re: CI tests (was: Re: [OT] Learning Makefiles)
Checking different configurations is an academic problem, I think they call it configuration sampling and it is part of variability modelling. There were some papers about sampling of Linux configurations. The simplest approach is to enable all possible, disable all possible, but it is not trivial. Each selection multiplies the number of configurations by the number of available options. That has very bad complexity. They use SAT solvers to generate many configurations instead of brute force. The goal is to sample configuration space in a uniform way. Am Mo., 22.

Re: [OT] Learning Makefiles
I see the following advantages of having CMake: - Everything is way more readable then the current Make files. - Easier on-boarding. - Less build-related bugs. - Less boiler-plate code. - Faster builds. - Great IDE integration. Adding CMake as an optional feature seems to be a great solution. Maintaining two systems for a while requires more work, but it would be a backward-compatible way to polish the solution. For trivial problems it is still just adding files to lists, right? For more complex issues, I am pretty sure that parties attached to Make will maintain it just fine and people who want CMake will fix it for themselves. The discussion so far was that: - Replacing Make breaks existing workflows. - CMake is less flexible. - Duplicated maintenance effort. By just adding CMake no workflows are broken If the new solution is able to recreate the previous build system, then it is flexible enough. I guess that overlapping maintenance effort is the only way to offer backward compatibility. I would like to point out that offering CMake is what people expect to have from a modern project and NuttX is currently not offering it. Am Fr., 19.

complains that
the process is not working.
Just to be sure I will test it today and maybe finish that documentation.

Re: ./tools/configure.sh | find -L | to follow symlinks
In general, you probably don't want to change files in the OS repository
just to attach your board.
I was supposed to document how to do this correctly, more than a half year
ago. I didn't, but what you need is described in this issue
https://github.com/apache/incubator-nuttx/issues/2206#issuecomment-721138548
The whole idea is to call `./config.sh` with a relative path. Other than
this you need to nest your board configuration in particular folder
structure. I don't remember exactly, but what is in that issue is correct
and supported.

Re: [Discuss] Migrate the build system to CMake
Quoting Sebastien: > It it's not broken, dont fix it. > - it works for its intended purposes > - it is pretty complex > - ALL USERS have become used to it Sebastien, what tools are you using for development? Make has such poor support for any tooling. Some IDE's understand it partially, some not at all. By using Make we are rejecting all the help that IDE's offer. NuttX code base is too large to work efficiently without it. Complex is not a feature I think. Yes, people are used to it, because they have to. The same way one can get used to winter or to walk in uncomfortable shoes. > No one will understand the build system anymore I have been looking at the current Make solution for the last few years and I wouldn't say I understand or control it either. Quoting Alin: > I like the cmake idea but we should also consider that cmake will have implications on all projects > that use the NuttX as a base for the SDK or custom projects. I am still stuck with NuttX 7.31 because of changes in the Make build system, so I understand what you are saying. My projects are small and I still don't have resources to migrate applications. I cannot even imagine how big of a burden it is, for developers of larger frameworks, but it shouldn't block progress. I think CMake will pay off over time. Quoting Nathan > Can't a CMake build be an OPTIONAL component for people who want to use it? Quoting Matias > Maintaining two build systems in parallel does not really make sense to me. Matias, just a question, does your work so far collide much with the current Make build system. I could take your branch and put the previous solution back next to your changes. It is hard to convince people to switch until they see that something works well. Quoting Juha > There is no problem to solve here but potential for massive breakage and extra burden > on companies using NuttX to develop real products. This is suggesting that everyone who considers CMake a good idea is an amateur. Yes, every change is a burden, but when projects don't develop, the look... well, like a Make build system. Quoting Ken > CMake is horrible. Don't do it. It's hard to use for beginners, and > hard to use for anyone who isn't just a strong advocate for it. Yea I don't like it either, I don't like either Make or CMake. I don't think that anyone likes them because they are just building systems, they are boring and unrewarding. But regarding beginners, I think you are wrong. One opens a project that uses CMake in an IDE and it works. Open a project that uses Make and it doesn't. After spending a lot of time trying to make it work, it is fine, but it is never perfect. Everyone who starts using NuttX needs to go through this. This is an unnecessary steep learning curve. We could say that this way, we filter out inexperienced people from producing noise in GitHub issues and the Internet in general, but with such an attitude it would be not right to call it an open source project anymore.

If I don't have experience with something I usually don't express my opinion. Don't feel that I am attacking you much, I just don't understand how this is a valid argument. Maybe you are just modest. It is hard to claim to be experienced with something even after many years of working with it. Yes, I also don't like CMake :) but I know what it brings, so I am fully in favor of it.

This is exactly what I thought when I read it. If some people didn't like it why did they wait for so long?

Also you should wait for the Earth to rotate a bit, so all people involved can wake up, think about it, finally argue a bit with each other. But I understand your disappointment when reading this. I would help you with CMake if I wouldn't be working 14 hours a day trying to finish delayed projects. Yet I was looking forward to a day when I could finally use it. In general I feel like you have a good hunch about good solutions and I am using a lot of them, either trying to update NuttX to a version where you already added something or cherry-picking like crazy.

Hello, I would suggest making merge request to the documentation inside repository. Confluence document could be copied there and then ascii art added. But it is my personal opinion. Not sure what was decided about confluence wiki. Yet, I had an impression that documentation should be gradually moved to the repository. Regarding ascii art itself, why not make a normal diagram. I think there is simple graphing syntax available called mermaid or you could attach svg. -- Maciej On Thu, 31 Dec 2020, 15:48 Grr, wrote: > Hello to all. > > I'm new into NuttX development and I made an ASCII-art function map of > NuttX initialization to hep update and improve > > https://cwiki.apache.org/confluence/display/NUTTX/NuttX+Initialization+Sequence > and I'd like to know of Brennan Ashton thinks it can be incorporated into > his document > > My map is based on startup for stm32f4discovery board and doesn't have > _all_ the functions but covers pretty much all the most important to give a > very good idea of initialization in a graphic manner > > I'd also like to know what's the best practice to update text of the > aforementioned document since there are some parts to be updated according > to this up-to-date map > > I read somewhere I cannot attach file here so please tell me how to share > it > > Thanks in advance >
Re: UPD send delay
In case of board I was working with, the network traffic was handled by low priority work queue. It is probably the same with your network driver. Such work queue has configuration. Maybe you need to change some parameters of it. It might help if you send here your configuration file, or part of it.

Re: sim target failures 10.0 branch
Hi Brennan, I would gladly join you with checking some of the boards in this table. For example I have some nostalgic relation with `hymini-stm32v` my first board :D Just removed the dust from it and flashed with NuttX 10. It is almost working :) (it was hanging on the missing SD card for a minute, what it shouldn't be doing, but started afterwards and displayed the NuttX logo) Maybe we could come up with a concept of board maintainers (people who check few boards of choice before release). There would be a table in documentation with a list of boards and maintainers on the side. It would be visible which are the orphans and maybe people would pick them over time. Am So., 25.

Re: Color ANSI support in nsh
There is a debug menu of NuttX configuration in which you can enable different levels of logging. You could add an option to differentiate colours based on debug level. I think this would be both great and doable. Then if it would be accepted, expose colorful logs to applications somehow. I wasn't using application level logging recently, just `printf|s. Don't know how it works now, but it should also be doable. On Mon, 17 Aug 2020, 13:34 Christian Catchpole, wrote: > Thanks everyone. There's obviously different levels of how far you take > it.

Re: Color ANSI support in nsh
I am confused a bit. Are you all guys talking about the same thing? If I understand correctly Christian just wanted to introduce colors to NSH. Colours in the terminal are not about looking good. Colours improve readability. The same text on the screen carries more information. This is why everyone is using syntax highlighting in the editor when programming. It is easier to spot red error and yellow warning than just all black text in terminal log. It would be great if there would be native option to enable this, without pdcurses.

Re: Markdown READMEs?
Sure, Matias. I was not addressing your proposition in any way. I was just commenting on existing format of READMEs. I am neutral regarding separate repository with documentation. At least at the moment, I need to sleep with the idea (more). Some if not all READMES will stay in the repository and I was suggesting reformatting them. Am Fr., 17.

Re: Markdown READMEs?
Regarding Markdown: I don't feel like I contribute here enough to have meaningful vote, but: Readmes in Markdown are present in almost every GitHub, GitLab project. In particular in almost every Python, Node.js, React/Angular/Vue project. Also quiclky looking at some C projects - https://github.com/lvgl/lvgl/blob/master/README.md - https://github.com/ARMmbed/littlefs/blob/master/README.md - https://github.com/warmcat/libwebsockets/blob/master/README.md `.md` extension stands for Markdown. It seems to be the de-facto standard. > Plain text is the best on cmd line environments (ssh/putty) Markdown is still a plain text. > I would second that: (1) plain text with no embedded tags, and (2) no new tools. No new tools are required. The only difference is that some editors and GitHub will display it in more readable way. It is almost like the previous text format that is already in the repo, it is just standardized and widely adopted. Syntax is non intrusive. It clearly separates code fragments with backticks. Renders headers and lists in a more readable way. Allows for a table, image and clickable link from time to time. It also allows separating code fragments and then it enables syntax-highlighting. This improves readability greatly. The format is actually simpler than the current one. Regarding RST format: It is a similar concept. It just seems to be a little bit more complex to help writing documentation of code in larger projects. I am seeing it for the first time, but I am also happy to help with Adam Feuer effort if you would decide to use this one. What I think would be great, is to pick any of this two standards. I was trying to parse existing documentation how it is now and it is problematic. The conventions are not always followed and fragments of code randomly glue to text when I am trying to retrieve paragraphs from it. My parsing issue is not relevant, but standardization is important. And Markdown is more readable, thanks to support from modern tools like VSCode or GitHub/Lab. While still being readable in Vim through SSH. Am Fr., 17.

Re: Markdown READMEs?
> what do you think about using Markdown for README files? Since the project was very conservative so far, I used regular expression to parse some existing files into Markdown. Although it is not completely reliable. I also think that markdown in repository would be great. Even trying to sneak in some first Markdown file already :D https://github.com/apache/incubator-nuttx-apps/blob/2fdd7529251919315bce62ceb0b130d7f135c506/graphics/lvgl/README.md > One of the reasons I really like the Zephyr docs... Yes, it is also my impression. This is why I am trying to create interactive documentation right now. Kconfig NuttX data is extracted using the same library as Zephyr does. Here are some existing READMES parsed into markdown http://nuttx-config.nxtlabs.pl/#/apps. To be more specific apps/*/README.txt files. I would like to add boards section as well in form of tiles with pictures and board configuration support comparison inspired by this https://node.green. Complete tree of READMEs with a search is also in my mind https://gitlab.com/nuttx-upm/kconfig-browser/web-ui/-/issues/25 How it works: currently there is a pipeline which runs for multiple tags/branches (master, releases/9.1, releases/9.0, ...) and extracts data into static JSON. Then Vue.js application is trying to render it. Pipeline triggers automatically weekly to keep the master fresh. Am Do., 16.

Re: NuttX 9.X C++11 Support
Right, newlib is C library. I feel dumb right now, because it seems I didn't know what I was using. But it is still something that C++ library provided by ARM GCC distribution was only working for me with both main package of ARM GCC and additional ARM newlib package installed. I was not digging into it because it was working. Maybe C++ library which they provide doesn't work without newlib. As Greg said, don't use it. I will also explore other options now.

Re: NuttX 9.X C++11 Support
I was using newlib. It is bundled with ARM GCC toolchain, at least on Ubuntu and Arch. Worked out of the box, except I remember having minor build issues from time to time, when adding additional headers. This question was appearing here in the past. I am also not sure what is the official answer. If I remember correctly many libraries work, but none of them is supported by NuttX. By not supported, I mean people are still trying to help with issues, but there is no official recommendation nor guarantee. C++ STL implementations are big projects, constantly changing and toolchains are not always sane in terms which headers they are trying to use. For example they may take a bit of NuttX libc, and mix it with a bit of its own headers. Then feed it to C++ STL giving unpredictable result in the end. I am not sure if anything that I am writing above makes sense :D In practice newlib was working, but probably not good for critical applications. I would also be happy to hear what is the official statement on it now. By the way, such GCC with newlib offers all higher C++ standards, not just C++11.

Re: NuttX config browser
They released today mentioned IDE https://os.mbed.com/blog/entry/mbed-studio-1-release It is literally vscode with few plugins. We could go the same way and do NuttX Studio :) For the beginning I could just provide instructions on how to use vscode with NuttX both for local and remote development. I was already using vscode for NuttX development, for some time, and it has good C/C++ support in comparison to other IDEs. With such instructions, we can identify what are the main issues and try to address them. Also PlatformIO and Mbed Studio plugins might be open-source, then we could just recommend them if they work or try to fork. Am Mo., 1.

Re: NuttX config browser
Hello Alan, A suggestion: when the user click on the option it should be nice to > see the Help for that option. Sure, I will add a side pane. Regarding online IDE. I was trying few times to switch to online development. The problem is that to debug or even to connect to nsh, one still needs local software and local copy of entire project. Which is against the basic reason why we would like to develop online. It is also a bit difficult to come up with own, custom online IDE. It is simply a lot of work, for a team of people. That being said I can easily imagine using existing online IDE to develop NuttX project. It could be just described how to do it efficiently. For example git repository can be cloned to GitLab and opened with their IDE. Then binary comes from pipeline which can be flashed to the microcontroller. Some simple client can be created which automates flashing. Still the issue of debugging remains. I will take a look at MBED and see how did they solve the issue. Am So., 31.

I will work on this configuration browser more and I am glad to contribute it if the community will find it useful. Regarding the other tools, I had one more project but I overcomplicated it and it ended up nowhere. I am still working on it from time to time, but I can't promise it will ever be production ready.

Re: MSYS2 build slow
Thanks for explanation. I went through that PR right now. I was just reporting as a good citizen :) I will check Issue pane next time before spamming.
NuttX config browser
Hello, On many occasions I want to lookup configuration options in NuttX and I found it inconvenient to run `menuconfig` for this. So I quickly created a small web interface and deployed it here http://nuttx-config.nxtlabs.pl It allows browsing and simple filtering of configuration entries. It searches in keys, titles and descriptions. Shows only keys and titles, for performance reasons. I would also like to add a side pane which shows more details about selected entry and allows jumping between related entries. Right now something is missing to make it human friendly. Am I not reinventing a wheel here? How do you handle this? Would community benefit from such UI?

Re: Should we relax precheck a little bit?
Are you sure that clang-format cannot indent macros? What about IndentPPDirectives: PPDIS_AfterHash It also treats the outmost macro in headers in a special way.
