Posted on August 19, 2014 at 16:44 I include emwin and FreeRTOS library and write GUI_Init(); function. I want to see 'hello world' on LTCD but didnt. firstly, I saw white screen after display has turned black increasingly. I'm giving code below. I would be glad if you could help.
#include ''main.h''
#include ''GUI.h''
#include ''stm32f4xx.h''
#include ''stm32f429i_discovery_lcd.h''
void TaskMask();
int main()
{
RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_CRC,ENABLE);
TaskMask();
}
void TaskMask()
{
int xPos, yPos;
GUI_Init();
SDRAM_Init();
GUI_Clear();
GUI_SetFont(&GUI_Font8x15B_ASCII);
GUI_SetBkColor(GUI_RED);
GUI_DispStringAt(''celalettin'',4,5);
xPos = LCD_GetXSize() / 2;
yPos = LCD_GetYSize() / 3;
GUI_SetFont(GUI_FONT_COMIC24B_ASCII);
GUI_DispStringHCenterAt(''Hello world!'', xPos, yPos);
}
