MI0283QT-17CP1 LCD mit ILI9341V Controller

Question

Ich versuche, das MI0283QT-17CP1 2,8 'TFT LCD mit dem ILI9341V Treiber zu verwenden, der das serielle 8080 8 Bit Datenprotokoll verwendet. dies ist mein Code für die Initialisierung:

ich für Start bin versucht zu ziehen scheinen, die alle Bildschirm in rot (5-6-5 RGB-Format) und kann nichts zu zeichnen ... ich bereits geprüft alle HW-Leitungen wie Reset, CS, Data/Command und alle Datenleitungen. Hat jemand mit diesen Einstellungen gearbeitet und kann mir sagen, was ich falsch mache? Danke, Avner

Answer 1

ok, also fand ich die Antwort, es war nicht im Initialisierungscode, aber in der Farbgebung des Bildschirms. habe vergessen, einen Gram-Befehl hinzuzufügen, der das Schreiben von Daten auf den Bildschirm sram setzt. so jetzt meine Färbung Funktion ist wie folgt:

void LCD_MNG_FillRect(uint16_t Xpos, uint16_t Ypos, uint16_t Width, uint16_t Heigth, LCD_COLORS_NAMES Color) 
{ 
     uint32_t Index; 
     uint16_t DisplayColor; 
     uint32_t Size = (uint32_t)(Width * Heigth); 
     LCD_InitDrawImage(Xpos, Ypos, Width, Heigth); 
     DisplayColor = LCD_MNG_CreateColor565((uint8_t)LCD_ColorsList[(int)Color].Red, (uint8_t)LCD_ColorsList[(int)Color].Green, (uint8_t)LCD_ColorsList[(int)Color].Blue); 
     LCD_Send_Command(ILI9341_GRAM); // this was missing... 

     for (Index = 0; Index < Size; Index++) 
     { 
       LCD_DisplayNextPoint(DisplayColor); 

     } 
} 

Ich hoffe, das andere zu helfen.
