Hi everyone

I'm trying to display on LM19264k LCD which is controlled by 3 controllers of type S6B0108 I'm usingthree instances of GUIDRV_SPage display driver of emWin and a GUIDRV_DIST driver of emWin. I'm able to display on the LCD, the problem is that when I tried to display my name ''Salahuddin'' on the LCD using

GUI_DispStringAt(''Salahuddin Ashraf'', 0, 0);

my name was displayed 4 timesvertically and 3 timeshorizontally .. and it was overlapped like this ''Ashrafdin'' here's my code // // Physical display size (128 x 64) // #define XSIZE_PHYS 192 #define YSIZE_PHYS 64 // // color conversion // #define COLOR_CONVERSION GUICC_1 // // Display driver // #define DISPLAY_DRIVER GUIDRV_SPAGE_1C0 // // Buffers / VScreens // #define NUM_BUFFERS 1 // Number of multiple buffers to be used #define NUM_VSCREENS 1 // Number of virtual screens to be used /********************************************************************* * * Public code * ********************************************************************** */ /********************************************************************* * * LCD_X_Config * * Purpose: * Called during the initialization process in order to set up the * display driver configuration. * */ void LCD_X_Config(void) { CONFIG_SPAGE Config = {0}; GUI_DEVICE *pDevice, *pDevice0, *pDevice1, *pDevice2; GUI_PORT_API PortAPI = {0}; GUI_RECT Rect0, Rect1, Rect2; // // At first initialize use of multiple buffers on demand // #if (NUM_BUFFERS > 1) GUI_MULTIBUF_Config(NUM_BUFFERS); #endif // // Set display driver and color conversion for 1st layer // On success the function returns a pointer to the created device object, // otherwise it returns NULL // pDevice = GUI_DEVICE_CreateAndLink(GUIDRV_DIST, COLOR_CONVERSION, 0, 0); // // Display driver configuration, required for Lin-driver // if (LCD_GetSwapXY()) { LCD_SetSizeEx (0, YSIZE_PHYS, XSIZE_PHYS); LCD_SetVSizeEx(0, YSIZE_PHYS * NUM_VSCREENS, XSIZE_PHYS); } else { LCD_SetSizeEx (0, XSIZE_PHYS, YSIZE_PHYS); LCD_SetVSizeEx(0, XSIZE_PHYS, YSIZE_PHYS * NUM_VSCREENS); } LCD_SetVRAMAddrEx(0, (void *)VRAM_ADDR); // // Create first display driver // pDevice0 = GUI_DEVICE_Create(DISPLAY_DRIVER, COLOR_CONVERSION, 0, -1); // // Configuration of first driver // // // Driver configuration // Config.FirstSEG = 0; Config.FirstCOM = 0; GUIDRV_SPage_Config(pDevice0, &Config); // // Configure hardware routines // PortAPI.pfWrite8_A0 = vWriteCommand; PortAPI.pfWrite8_A1 = vWriteData; PortAPI.pfWriteM8_A1 = vWriteDataM; PortAPI.pfRead8_A1 = u8ReadData; PortAPI.pfRead8_A0 = u8ReadStatus; GUIDRV_SPage_SetBus8(pDevice0, &PortAPI); // // Controller configuration // GUIDRV_SPage_Set1510(pDevice0); // // Create second display driver // pDevice1 = GUI_DEVICE_Create(DISPLAY_DRIVER, COLOR_CONVERSION, 0, -1); // // Configuration of second driver // // // Driver configuration // Config.FirstSEG = 0; Config.FirstCOM = 0; GUIDRV_SPage_Config(pDevice1, &Config); // // Configure hardware routines // PortAPI.pfWrite8_A0 = vWriteCommand; PortAPI.pfWrite8_A1 = vWriteData; PortAPI.pfWriteM8_A1 = vWriteDataM; PortAPI.pfRead8_A1 = u8ReadData; PortAPI.pfRead8_A0 = u8ReadStatus; GUIDRV_SPage_SetBus8(pDevice1, &PortAPI); // // Controller configuration // GUIDRV_SPage_Set1510(pDevice1); // // Create third display driver // pDevice2 = GUI_DEVICE_Create(DISPLAY_DRIVER, COLOR_CONVERSION, 0, -1); // // Configuration of second driver // // // Driver configuration // Config.FirstSEG = 0; Config.FirstCOM = 0; GUIDRV_SPage_Config(pDevice2, &Config); // // Configure hardware routines // PortAPI.pfWrite8_A0 = vWriteCommand; PortAPI.pfWrite8_A1 = vWriteData; PortAPI.pfWriteM8_A1 = vWriteDataM; PortAPI.pfRead8_A1 = u8ReadData; PortAPI.pfRead8_A0 = u8ReadStatus; GUIDRV_SPage_SetBus8(pDevice2, &PortAPI); // // Controller configuration // GUIDRV_SPage_Set1510(pDevice2); // // Add display drivers to distribution driver // Rect0.x0 = 0; Rect0.y0 = 0; Rect0.x1 = 63; Rect0.y1 = 63; GUIDRV_Dist_AddDriver(pDevice, pDevice0, &Rect0); Rect1.x0 = 64; Rect1.y0 = 0; Rect1.x1 = 127; Rect1.y1 = 63; GUIDRV_Dist_AddDriver(pDevice, pDevice1, &Rect1); Rect2.x0 = 128; Rect2.y0 = 0; Rect2.x1 = 191; Rect2.y1 = 63; GUIDRV_Dist_AddDriver(pDevice, pDevice2, &Rect2); // // Set user palette data (only required if no fixed palette is used) // #if defined(PALETTE) LCD_SetLUTEx(0, PALETTE); #endif } Can anyone tell me how to fix this and how to write on the LCD like just one LCD not three similar LCDs ?
