I am trying to use the MI0283QT-17CP1 2.8' TFT LCD with the ILI9341V driver using the serial 8080 8 bit data protocol. this is my initialization code:

I am trying for start to draw the all screen in red (5-6-5 RGB format) and can't seem to draw anything... I already checked all the HW lines such as reset, CS, data/command and all the data lines. Did anybody worked with this settings and can tell me what I am doing wrong? Thanks, Avner
ok, so I found the answer, it wasn't in the initilaiztion code, but in the coloring of the screen. forgot to add a Gram command that sets the writing of data to the screen sram. so now my coloring function is like this:
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);
}
}
I hope this will help others.
