Mad River

Hi @inmarket, I am using version 2.7, which I downloaded from the uGFX official site. isn't it the lastest version?

Based on the FreeRTOS port, I made like 70% of the ThreadX port. But there are some functions that I didn't understand. I attached the source code. Every question is marked with a // TODO Any advice or tip will be apreciated. gos_threadx.c gos_threadx.h

Hi, I am currenty working on a project which uses Synergy S3 as uController and ThreadX as RTOS, As ThreadX is not presented in the supported RTOS list, I will have to create a "ugfx/src/gos/gos_threadx.c" and "ugfx/src/gos/gos_threadx.h". Is there a guide on how to do it? If not, which tips can you give me to help me do it? Thank you!

@cpu20 @Joel Bodenmann It finally worked, even with the blink led project provided by Renesas. Thank you very much for your help and pacience. Now, probably I will need some help to port the low-level and MAYBE the RTOS (ThreadX), but I will open a new thread about it.

It worked now! But, in addition for your steps, I need to remove "gfx.h" from the filter list. Is it ok? Anyway, it worked for a clean GNU Hello World project. I will try again to do the same steps to my board (Renesas Synergy S3) using provided blink led project.

@cpu20 I am following your steps, from scratch. I did not understand "do not select the src map!" But, that is how it is now:

@cpu20 I excluded all files from the build, the only exception is the gfx_mk.c. It compiled. But the problem remains. It still seems that the TRUE is used correctly.

Hi @cpu20, Thank you for your reply. How should be the filter to exclude all files except the gfx_mk.c?

About the error related to the bool_t, seems like the TRUE in the config file is not working. I am using "#define GFX_USE_OS_RAW32 TRUE" in the config file. But in "gos.h" everything is grey. (Image attached). I am also trying to create the tick functions in my own code and it is not getting the TRUE correctly. (Image attached). EDIT: I attached a image that shows a compiler warning about the TRUE. In the image that shows my own code, in "if GFX_USE_OS_RAW32" the value of GFX_USE_OS_RAW32 is '0'. I think my compiler is not understanding the '-1' definition.

Done. Project is compiling well (only the /project/src). Done. Project still compiling. I could not find a way to include a single file to the build path. I only found a way to include a folder. So, I moved the "gfx_mk.c" from "/project/ugfx/src" to "/project/src". Is it a problem? The project is still compiling. EDIT: I am getting a error about the bool type, which I don't have in my project. "'bool_t' could not be resolved gfx.c /ugfx_project/ugfx/src line 18 Semantic Error" That is the line: static bool_t gfxInitDone = FALSE; Thank you all for the help!

Hi @Joel Bodenmann I managed to remove that error. I had to explicit add the include path "/ugfx/src/gdisp/mcufont" before "ugfx_project\src\ugfx". Now it is finding the correct file first. But I am getting a new error now: fatal error: 'linux/input.h' file not found gmouse_lld_linux_event.c /ugfx_project/src/ugfx/drivers/ginput/touch/Linux-Event line 10 I am not even using any drivers. As I said, I have copied/pasted the full ugfx folder to my project. I supposed that it should only try to compile the drivers selected in the gfxconfig.h. But it seems that it is trying to compile all files inside the folder. I think I should copy/paste only the needed folders, but I can't tell which ones are essencial. Can you help me with that?

Hi @cpu20 and @Joel Bodenmann Thank you both for your replies. As it seems easy, I will stay with the single-file-include approach. I did as the guide you mentioned, but it is still not compiling. These are EXACTLY the steps I made: 1. Loaded a example application which blinks a LED. 2. Downloaded the uGFX lib and extracted it. 3. Renamed it from "ugfx_2.7" to "ugfx" and copy/paste it as it is (full folder content) to the src directory of my project. The path is "ugfx_project\src\ugfx" 4. Created a gfxconfig.h inside "ugfx_project\src\ugfx". 5. Change "#define GFX_USE_OS_RAW32" from FALSE to TRUE. 6. Added "ugfx_project\src\ugfx" to the include path. 7. Tried to compile. I got that error in the font files: [file: DejaVuSans10.c] #include "mf_bwfont.h" #ifndef MF_BWFONT_VERSION_4_SUPPORTED #error The font file is not compatible with this version of mcufont. #endif As I could see, MF_BWFONT_VERSION_4_SUPPORTED is really defined in the "mf_bwfont.h". That file is located at: "ugfx_project\src\ugfx". The problem is that the "DejaVuSans10.c" is seeing another "mf_bwfont.h" which contain only this: /* This is a stub file to prevent having to include the mcufont * directory in the include path for funny compilers such as arduino * which don't support a user specified include path. * * It is not needed anyway as the files are already included. * * New versions of the font generator do not generate these include lines. */ So, I assumes that the MF_BWFONT_VERSION_4_SUPPORTED is not defined and crashes. What can I do to point to the correct "mf_bwfont.h" file?

Still can't compile it. If it can help, attached are some files generated by the compiler. makefile objects.mk sources.mk

I can use the makefile approach, I just don't know how. The instructions are not clear enough for me. Step-by-Step guide: Set the GFXLIB variable to the path pointing to the µGFX library root directory Include the main µGFX Makefile (/ugfx/gfx.mk) Add GFXSRC to the sources variable/list Add GFXINC to the include paths variable/list Include additional Makefiles of the µGFX library to include board files, drivers, ... Please, see the attached image. I think that is the right place to place the variables mentioned in the Step-by-Step guide. I have created the GFXLIB and pointed to the extracted folder. I am not sure what to do in steps 2, 3 and 4. Can you help me?

Hi @Joel Bodenmann! I am trying to do the "single-file-inclusion". As said in the documentation, I copied the gfx_mk.c to my project root directory. I am using e²studio (Renesas), which is a Eclipse based IDE. Is there a tutorial on how to configure this IDE to compile uGFX?

Hi, I just downloaded the uGFX library and tried to add it to a "blink led" project. But I am getting some compilation errors. (Print-screen attached). Seems like the files are not "seeing" eachother correcly. I have extracted the zip file to my project directory and added the following lines to the include list: "${workspace_loc:/${ProjName}/src/ugfx_2.7}" "${workspace_loc:/${ProjName}/src/ugfx_2.7/src}" I am not sure what configs should I set in the config file. (gfxconfig.h attached). Regarding the error, the MF_BWFONT_VERSION_4_SUPPORTED is defined in the mf_bwfont.h: /* Versions of the BW font format that are supported. */ #define MF_BWFONT_VERSION_4_SUPPORTED 1 gfxconf.h
