When copying library files like gfx_mk.c to your own project you prevent that from working. We strongly advice against doing that.

Sorry, but I couldn't find another solution how to include your library in Eclipse project. I tried many approaches.

They are not useless

Maybe. But in my case, I had found the required parameters before understood what these scripts are doing.

I understand that this is some kind of piggery, but is it some image resize mechanism in library?

I found solution. Protect 'disk_read' function:

DRESULT disk_read(BYTE lun, BYTE *buff, DWORD sector, UINT count)
{
	DRESULT res = RES_OK;
#if FREERTOS_IS_USED
	taskENTER_CRITICAL();
#endif
	if (BSP_SD_ReadBlocks((uint32_t*) buff, (uint64_t) (sector * BLOCK_SIZE), BLOCK_SIZE, count) != MSD_OK)
		res = RES_ERROR;
#if FREERTOS_IS_USED
	taskEXIT_CRITICAL();
	osDelay(1);
#endif
	return res;
}

And some final question.

Cause I protected whole drawing function:

		taskENTER_CRITICAL();
		received_img_error = gdispImageDraw(&myImage, 0, 0, image_width, image_height, 0, 0);
		taskEXIT_CRITICAL();

As you see, while image is in drawing process, all other threads are stopped, cause scheduler is freezed.

As I could understand, function 'gdispImageDraw' loads image to display line by line (the same mechanism as in emWin), so for my purposes it will be more suitable to protect just SD reading process, not whole function. How can I implement such behavior?

GUYS I LOVE YOU!!!!

SO MUCH!!!!

IT CYCLING IMAGES WITHOUT ANY TROUBLES!!!!!

The same trouble as with emWin. User should protect image drawing process:

	taskENTER_CRITICAL();
	received_img_error = gdispImageDraw(&myImage, 0, 0, 300, 225, 0, 0);
	taskEXIT_CRITICAL();

Ok guys, finally I wrote my IO functions for your FATFS, and its working.

But I couldn't use external to uGFX FATFS lib, and this definitely a bug. Hope you will fix it.

Will see what shows next tests.

I tested FATFS again and it's working:

My code for such test is the next:

/*From FATFS*/
	FIL ImgFile;
	FRESULT res;
	FATFS fileSystem;

	/*Debug*/
	char buffer[64] = { 0 };

	/*From uGFX*/

	GFILE* imgFile;
	coord_t swidth = 320,
			sheight = 240;

	static gdispImage myImage;
	MX_FATFS_Init();

	if (f_mount(&fileSystem, (TCHAR const*) SD_Path, 0) == FR_OK) { //FATFS mount drive

		/*Test for file existence*/
		res = f_open(&ImgFile, file_name[0], FA_OPEN_EXISTING | FA_READ);
		f_close(&ImgFile);
		/*End test for file existence*/

		imgFile = gfileOpen(file_name[0], "rb");
		received_error = gdispImageOpenGFile(&myImage, imgFile);
		gdispImageDraw(&myImage, 0, 0, swidth, sheight, 0, 0);
		gdispImageClose(&myImage);
	}
	gdispFillArea(0, 0, WINDOW_WIDTH, WINDOW_HEIGHT, Blue);
	sprintf(buffer, "Received error %x", (int) received_error);
	gdispDrawString(0, 0, buffer, font, White);
	gdispDrawString(0, 20, "Р—Р°РїСѓС‰РµРЅРѕ!!!", font, White);

October 12, 2016

Hi, Joel I did as you asked.

I have next error: GDISP_IMAGE_ERR_NOSUCHFILE

I divided my code a little, as you can see:

gdispImageError received_error;
	GFILE* imgFile;
	coord_t swidth = 320,
			sheight = 240;
	FATFS fileSystem;
	static gdispImage myImage;
	MX_FATFS_Init();
	if (f_mount(&fileSystem, (TCHAR const*) SD_Path, 0) == FR_OK) { //FATFS mount drive
		imgFile = gfileOpen(file_name[0], "rb");
		received_error = gdispImageOpenGFile(&myImage, imgFile);
		gdispImageDraw(&myImage, 0, 0, swidth, sheight, 0, 0);
		gdispImageClose(&myImage);
	}

But I tried booth approaches, with the same result.

Hello, Joel.

I tested these options. I found it in 'gfile_options.h' but couldn't found it in 'gfxconf.h'. So I added these options by myself - my 'GFILE' section looks like:

///////////////////////////////////////////////////////////////////////////
// GFILE                                                                 //

//#define GFILE_NEED_PRINTG                            FALSE
//#define GFILE_NEED_SCANG                             FALSE
//#define GFILE_NEED_STRINGS                           FALSE
//#define GFILE_NEED_FILELISTS                         FALSE
//#define GFILE_NEED_STDIO                             FALSE
//#define GFILE_NEED_NOAUTOMOUNT                       FALSE
//#define GFILE_NEED_NOAUTOSYNC                        FALSE

//#define GFILE_NEED_MEMFS                             TRUE
//#define GFILE_NEED_ROMFS                             FALSE
//#define GFILE_NEED_RAMFS                             FALSE
//#define GFILE_NEED_FATFS                             TRUE
//#define GFILE_NEED_NATIVEFS                          FALSE
//#define GFILE_NEED_CHBIOSFS                          FALSE

//#define GFILE_ALLOW_DEVICESPECIFIC                   FALSE
//#define GFILE_MAX_GFILES                             3

After that I tried to implement this code:

char* file_name[] = {
		"1_300x225_16bpp.bmp",
		"2_300x225_16bpp.bmp",
		"3_300x225_16bpp.bmp",
		"4_300x225_16bpp.bmp",
		"5_300x225_16bpp.bmp",
		"6_300x225_16bpp.bmp",
		"7_300x225_16bpp.bmp",
		"8_300x225_16bpp.bmp",
		"9_300x225_16bpp.bmp",
		"10_300x225_16bpp.bmp",
		"11_300x225_16bpp.bmp",
		"12_300x225_16bpp.bmp",
		"13_300x225_16bpp.bmp",
		"14_300x225_16bpp.bmp",
		"15_300x225_16bpp.bmp",
};

static gdispImage myImage;
FATFS fileSystem;
FIL ImgFile;
void GUI_thread(void const * argument) {
	gfxInit();
#if GFX_USE_GDISP && GDISP_NEED_TEXT
	font_t font = gdispOpenFont("ISOCPEUR Regular 20");
	gwinSetDefaultFont(font);
#if (DISPLAY_ORIENTATION == 0)
	gdispSetOrientation(GDISP_ROTATE_0);
#elif(DISPLAY_ORIENTATION == 90)
	gdispSetOrientation(GDISP_ROTATE_90);
#elif(DISPLAY_ORIENTATION == 180)
	gdispSetOrientation(GDISP_ROTATE_180);
#elif(DISPLAY_ORIENTATION == 270)
	gdispSetOrientation(GDISP_ROTATE_270);
#endif //DISPLAY_ORIENTATION

	coord_t swidth = 320,
			sheight = 240;
	// Set up IO for our image
	 MX_FATFS_Init();
	if (f_mount(&fileSystem, (TCHAR const*) SD_Path, 0) == FR_OK) {
		gdispImageOpenFile(&myImage, file_name[0]);
		gdispImageDraw(&myImage, 0, 0, swidth, sheight, 0, 0);
		gdispImageClose(&myImage);
	}
	gdispFillArea(0, 0, WINDOW_WIDTH, WINDOW_HEIGHT, Blue);
	gdispDrawString(0, 0, "Initialized!", font, White);
	gdispDrawString(0, 20, "Р—Р°РїСѓС‰РµРЅРѕ!!!", font, White);
	CreateGUI();
#endif //GFX_USE_GDISP && GDISP_NEED_TEXT
	for (;;)
			{
		gfxSleepMilliseconds(500);
	}
}

I mounted SD successfully (as always, STM's CubeMX FATFS implementation works pretty reliable).

But after i tried to fill 'gdispImage' structure, it doesn't happen - look for screenshot:

No hardfault, no any errors, it just not loads.

Can you give me some tip how to resolve this issue?

I understand, that in case of using uGFX FATFS library I should write complete driver to access SD card through SDIO, and I don't want to do it,

especially when this job had made already by STM's engineers.

B.R. Constantine.

1) I looked inside 'gfx_mk.c', and all what I've found is several file definitions.

From your previous post:

Quote

The problem is that upgrading to a newer version would require you to copy the file again

I'm not sure that you change file names for every new library release. On present moment it looks pretty stable.

2) I successfully build GUI under FreeRTOS based on your library in Eclipse. Tomorrow I'll try to describe whole process on my site.

3) SSD1963 driver pretty good. I changed nothing in code, except 'board' porting.

3.1) I think this is useless:

#define CALC_PERIOD(w,b,f,p) (p+b+w+f)
#define CALC_FPR(w,h,hb,hf,hp,vb,vf,vp,fps) ((fps * CALC_PERIOD(w,hb,hf,hp) * CALC_PERIOD(h,vb,vf,vp) * 1048576)/100000000)

October 8, 2016

If you worked in Eclipse for a long time, you should know that its errors not really mirroring what really happens))

October 8, 2016

Yes, Joel, absolutely.

It is pretty obvious in Eclipse, in project explorer you see all files of your Project directory.

October 8, 2016

Joel, I tried as you recommended.

That is the error:

...

Src/usbd_desc.o: In function `gfxInit':
D:\MY_WORKS\STM_projects\STM_HYDROFILTER_Eclipse_uGFX\Debug/./../ugfx/src/gfx.c:84: multiple definition of `gfxInit'

...

And some other useless warnings (not from uGFX library).

October 8, 2016

Hello, Joel.

I tried several approaches, but Eclipse/GCC environment is pretty capricious, and in most cases I catch different errors while building.

Only this reached success:

Add uGFX:
1. Copy 'uGFX' library folder to your Eclipse project folder
2. Add 'uGFX' to C/C++ Build pathes:
Properties for $Your_project -> C/C++ Build -> Settings -> Tool Settings -> Includes
add next pathes:
   ../ugfx
   ../ugfx/src
3. Copy 'gfx_mk.c' to '$Your_project/Src from ugfx/src'
4. Copy 'gfxconf.h' to '$Your_project/Inc' and config it.
5. Add next inclusions in 'main.c':
   #include "gfx.h"
   #include "gfxconf.h"

--

Most common errors is: "redefinition of gfxInit ..."

Later I will try again approach that you have offered, maybe I will find some solution.

B.R. Constantine.

Could somebody place this words in the frame at the enterance of this site:

Manual How to implement uGFX lib in existing Eclipse project with autotool makefile.

Copy ugfx lib folder to your Eclipse project tree and exclude it from build( click right button on folder and choose Resource Configurations).
Copy gfx_mk.c to your src from ugfx/src. Now all necessary sources and headers of ugfx include to build.
Copy gfxconf.h to your include dir and config it.
Choose or create necessary drivers and board files (BSP). You can choose them from ugfx/drivers and ugfx/boards. Copy necessary folders to your project tree and check including them to build. For example, f7-discovery(LCD + Touch Screen) requires folowing drivers: ugfx/drivers/gdisp/STM32LTDC and ugfx/drivers/ginput/touch/FT5336. Also you can take something usefull from board files ugfx/boards/base/STM32F746-Discovery
Specify following include paths:

"../ugfx"
"../dviver1 folder"
"../dviver2 folder"
"../board folder"

Thanks a lot Victor its working.

Thanks Joel.

I like you guys!

I always think the same:

#define Magenta Fuchsia

even if everybody say that this is not.

September 30, 2016

YES!

I just replace all mess code that is shipped with library (look file 'gdisp_lld_ILI9325.c') and everithing works!!!

Dear uGFX command. I'm not recommending you provide hardware code for LCD controllers. It is a way of errors.

Take code that I provided to you.

September 30, 2016

I'm trying to initialize display with ILI9325 and I've found that this is impossible.

I begin to check this driver and found completely strange initialization sequence. Code is complete mess - no register names, no values clues. Pretty bad programming style.

Did anybody had a success with this controller and uGFX's driver?

I have mine initialization routine, that works perfect by itself and with emWin. Look attachment.

Hello guys!)

Could somebody clearly explain what these two functions should do:

systemticks_t gfxSystemTicks(void){}

and

systemticks_t gfxMillisecondsToTicks(delaytime_t ms){}

/*

I'm using STM32 MCU with its awkward-to-handle HAL. And trying to build bare hardware)) project from this article:

https://wiki.ugfx.io/index.php/Using_Keil_µVision_5_MDK-ARM

*/

In HAL this function: HAL_GetTick() returns ticks, One tick == one millisecond.

It is obvious from this code - look file stm32fXxx_hal.c:

**
  * @brief This function provides accurate delay (in milliseconds) based 
  *        on variable incremented.
  * @note In the default implementation , SysTick timer is the source of time base.
  *       It is used to generate interrupts at regular time intervals where uwTick
  *       is incremented.
  * @note ThiS function is declared as __weak to be overwritten in case of other
  *       implementations in user file.
  * @param Delay: specifies the delay time length, in milliseconds.
  * @retval None
  */
__weak void HAL_Delay(__IO uint32_t Delay)
{
  uint32_t tickstart = 0;
  tickstart = HAL_GetTick();
  while((HAL_GetTick() - tickstart) < Delay)
  {
  }
}

It will be the same for any STM32 MCU.

So I try to implement it like this:

systemticks_t gfxSystemTicks(void){
        return ((systemticks_t)(HAL_GetTick()));
    }
        
    systemticks_t gfxMillisecondsToTicks(delaytime_t ms){
        return ((systemticks_t)ms);
    }

Because I suppose that 'gfxSystemTicks' provides system time for GUI library.

And 'gfxMillisecondsToTicks' converts some mysterious internal GUI ticks into millisecond.

I can compare this with emWin - there was just one variable 'extern volatile GUI_TIMER_TIME OS_TimeMS;'

that you should increment every millisecond. It serves for emWin like a command to refresh screen.

Hello, uGFX team.

Is it possible to find some manual about your library in some printable view? I prefer PDF, but will be glad to any type.

Most of my programming skills I received from Moscow metro. Every day I spend aprox. 3 hours in metro, and all this time I'm reading some special literature.

That is how I study emWin, FreeRTOS and NIOS II. It will be very helpful to have uGFX manual in printable view.

If it didn't created yet, I have some advise how it should look like.

This manual shouldn't be comprehensive review of all library including source code.

Just theory of operation, some examples and brief API description. All this aprox. on 300 - 500 pages, not more.

B.R. Constantine.
