Posted on May 07, 2015 at 17:54Hello,
I have managed to compile and run the stm32cubef4 libs, together with STemWin V5.26. I use the STM324x9I-Eval board with MB1046B display board. I can run all the included examples, plus the sample available on the Segger site.
The one i try to use in my project is ALPHA_Bargraph. It seems to run fine, with the
exception of the 'Draw alpha effect':
Rect.x0 = xPos;
Rect.x1 = xPos + 3;
Rect.y0 = yPos;
Rect.y1 = yPos + 122;
GUI_SetClipRect(&Rect);
GUI_SetColor(0xd99100);
GUI_SetAlpha(168);
GUI_FillRoundedRect(xPos, yPos, xPos + 172, yPos + 122, 4);
GUI_SetClipRect(NULL);
GUI_FillRect(xPos + 4, yPos + 1, xPos + xBlend, yPos + 122 - 1);
GUI_SetAlpha(0);
Commenting out the above code seems to speed up the displaying of the bar elements, but when enabled i don't see the blue rectangle that moves in the foreground when i run the Windows executable for this sample.
I have tried to check the configuration values, increase the available RAM for the library, etc, with no luck.
Here some of those settings:
#define GUI_NUMBYTES (1024) * 1024
unsigned long *mem = (unsigned long *)0xC0000000;
....
GUI_ALLOC_AssignMemory(mem, GUI_NUMBYTES);
....
#define GUI_NUM_LAYERS 2
#define GUI_OS (0)
#define GUI_SUPPORT_TOUCH (0)
#define GUI_SUPPORT_MOUSE (0)
#define GUI_WINSUPPORT (1)
#define GUI_SUPPORT_MEMDEV (1)
#define GUI_SUPPORT_DEVICES (1)
....
define XSIZE_PHYS 480
#define YSIZE_PHYS 272
#define NUM_BUFFERS 2 /* Number of multiple buffers to be used */
#define NUM_VSCREENS 1 /* Number of virtual screens to be used */
#define GUI_NUM_LAYERS 2
#define LCD_LAYER0_FRAME_BUFFER ((int)0xC0200000)
#define LCD_LAYER1_FRAME_BUFFER ((int)0xC0400000)
Maybe there is an extra configuration somewhere i have missed ? Thank you.
Regards, Chris
