Hello and welcome to the µGFX community!

The way to do this is by creating a custom widget. You can find the corresponding documentation here.
Judging from the fact that you already linked the matrix operations API documentation I assume that you know that you need to draw a needle polygon and then transform it, is that correct?
In order for us to help you efficiently it would be helpful if you could tell us what you already know/understand and what exactly your questions/problems are. Otherwise we have to write down a complete guide here ^^

You might want to have a look at this custom widget that you can download from the downloads section that does more or less exactly that. It's a lot uglier than yours but the logic behind is the same. You might be able to just take and modify that.
Note that we are using a PNG image as a background / dial / scale. The one you show in your photo can be drawn manually using arcs and lines. That will require way less memory than rendering a PNG image.

Please don't hesitate to ask if you have any other questions. We're happy to help!

Edit: This is the real API documentation for the matrix operations: http://api.ugfx.io/group___g_m_i_s_c.html

Hello ;
I was not able to run the program.
https://wiki.ugfx.io/index.php/Using_Keil_µVision_5_MDK-ARM I made the instructions here but did not.

Is the correction correct?can you check?

ım using uKEIL V5.22 / WINDOWS 10 / STM32F746NG DISCOVERY KIT

Can you please tell us what doesn't work?
If you have compile time errors, please attach a text file containing the entire output of the build process to your next forum post.

Also, please do not use colored fonts, larger fonts or similar things in your forum posts.

That looks very strange - nothing comes to mind right now.
Have you tried making a clean build? You can do that in Keil µVision by clicking Project -> Clean Targets. Then make a new compile. It should restart from the very beginning this time. Can you attach a text file (like you did before, great!) with that clean build output log?

So far you are only getting one error:

..\ugfx\src\gfile/gfile_fs_rom.c(36): error:  #5: cannot open source input file "romfs_files.h": No such file or directory

This error means that the file romfs_files.h couldn't be found by the compiler.
The romfs_files.h file is required when you are using ROMFS (if GFILE_NEED_ROMFS is set to TRUE). If you don't actually use ROMFS then simply set it to FALSE. If you need ROMFS then create a file named romfs_files.h where you include all the converted ROMFS files (the files converted with file2c.exe).
You can find the corresponding documentation here: https://wiki.ugfx.io/index.php/ROMFS

Hi,

I think you misunderstood with the text files: Only attach text file containing large, generated things like your compiler output. Don't keep your actual explanations, what you did and questions in there. These things belong directly in your forum post. So to summarize: Stuff you want to say/ask -> Forum post    Larger text files that are relative (like compiler outputs, configuration files and similar) -> attach a text file to the same forum post.
That is very important, please re-read it carefully.

I'll quote your text file:

Quote

#define GFILE_NEED_NATIVEFS FALSE ///if � change to true this value � get "sys/types.h" error?

but � search in wiki "https://wiki.ugfx.io/index.php/Images" � dont want use rom, use native,cause native is good then roms.but � cant use.

 

� get error :

 

..\ugfx\src\gfile/gfile_fs_native.c(22): error: #5: cannot open source input file "sys/types.h": No such file or directory

 

#define GFILE_NEED_ROMFS FALSE (when true : search roms. when include roms )

Not enough information to list image symbols.

Not enough information to list the image map.

 

#define GFILE_MAX_GFILES 5

 

I do not know what i should do :(

You cannot use the NativeFS in your case. NativeFS is just a file system wrapper that allows using the native file system of the underlying system (if any). For example, when you're running your application on Windows or Linux, you can use NativeFS to directly access files on your computer's hard disk through GFILE. You are not using an underlying operating system that offers a native file system and hence you can't use NativeFS.

If you want to use files (eg. if your µGFX application wants to load images and other resources from files) then use ROMFS. It's the best option you have. It's super small & efficient and very easy to use. Otherwise you have to use FatFS or something else that is way more complex and way more resource intensive.

So, to summarize: If your µGFX application doesn't need access to files, simply turn the GFILE module off in your configuration file. If your µGFX application needs access to files, then simply use ROMFS in your case. Follow the documentation linked above, create your romfs_files.h files, add it to the project, convert all the files you need to access through ROMFS with file2c.exe, include the generated header files in romfs_files.h and you're done.

I did exactly what you said. And I got help from the link above :) It was really useful. But ı got same error("Error.txt")

ı search that error ı found but ı dont understand.Maybe you know what you mean (http://www.keil.com/support/docs/3724.htm)

 

I did not add the error list because the same ("Error.txt")

thnx.C  ya

It can be the same two variables. So I have to check the names of all the projects I have combined, but again the same fault.

 

The mind does not come any more. But I feel we will be successful at the end I hope

Can you please attach your Keil project as a ZIP or RAR archive so we can have a look? Please don't forget to clean the project first (Project -> Clean all targets) to keep unnecessary large binaries out of it.

We'll have a look at this, but that might take a few days. Stay tuned!

If you have any questions in the meantime please don't hesitate to ask. We're happy to help wherever we can.

We had no time to dive into this yet, I'm afraid.
I can't promise that we'll find time for that this week. If this is of importance due to a deadline of a commercial project or something like that please contact us if you want to get priority support (paid support).

This project is not paid for me. Just to learn. But if I make a project with money, I definitely ask you.

If it is a simple project is $ 25 ?

The project I sent you is your demon. But it did not work, so it is not a hard error for you :-)

I just had the time to download and try building the project. Did you even read the error message that you're getting? It tells you exactly what the issue is.
