[ARM] Displaying array to LCD ?

[bianchi77]

Guys,

Does anyone of you know on how to display array of bitmap to TFT LCD ?

I tried :

void LCD_DrawBMPFromFile()
 {											 
   	char temp_buffer[100],line[512];
	int count,bmpData,bmpAddr;

  	const int icon[220] =
    {
	0x42,0x4D,0xC6,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x76,0x00,0x00,0x00,0x28,0x00,0x00,0x00,0x0A,
	0x00,0x00,0x00,0x0A,0x00,0x00,0x00,0x01,0x00,0x04,0x00,0x00,0x00,0x00,0x00,0x50,0x00,0x00,0x00,
	0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,
	0x00,0x00,0x00,0x80,0x00,0x00,0x80,0x00,0x00,0x00,0x80,0x80,0x00,0x80,0x00,0x00,0x00,0x80,0x00,
	0x80,0x00,0x80,0x80,0x00,0x00,0x80,0x80,0x80,0x00,0xC0,0xC0,0xC0,0x00,0x00,0x00,0xFF,0x00,0x00,
	0xFF,0x00,0x00,0x00,0xFF,0xFF,0x00,0xFF,0x00,0x00,0x00,0xFF,0x00,0xFF,0x00,0xFF,0xFF,0x00,0x00,
	0xFF,0xFF,0xFF,0x00,0xFF,0xFF,0xFF,0xFF,0xFF,0x00,0x00,0x00,0xFF,0xFF,0xFF,0xFF,0xFF,0x00,0x00,
	0x00,0xFF,0xFF,0xFF,0xFF,0xFF,0x00,0x00,0x00,0x99,0x99,0x99,0x9F,0xFF,0x00,0x00,0x00,0x99,0x99,
	0x99,0x9F,0xFF,0x00,0x00,0x00,0x99,0x99,0x99,0x9F,0xFF,0x00,0x00,0x00,0x99,0x99,0x99,0x9F,0xFF,
	0x00,0x00,0x00,0x99,0x99,0x99,0x9F,0xFF,0x00,0x00,0x00,0x99,0x99,0x99,0x9F,0xFF,0x00,0x00,0x00,
	0x99,0x99,0x99,0x9F,0xFF,0x00,0x00,0x00};


  //write LCD RAM here
			LCD_WriteRAM_Prepare(); /* Prepare to write GRAM */
		  	LCD_Clear(Yellow);
		 for (bmpAddr; bmpAddr < 100; bmpAddr += 2)
		  {
		    bmpData = (uint16_t)(*(icon + bmpAddr)) + (uint16_t)((*(icon + bmpAddr + 1)) << 8);
		    LCD_WriteRAM( bmpData );
		  }


 __inline void LCD_WriteRAM(uint16_t RGB_Code)					 
				 
{
  /* Write 16-bit GRAM Reg */
  LCD_RAM = RGB_Code;
}

but got no response, any clues ? thanks

What TFT is it? Have you tried a hello world code to make sure there is communication?

It's SD1289, I have tested with GUI_Text and it's working fine...any clues ? thanks
