Merhabalar. Bir projede PIC18F87K22 kullanarak SSD1963 barındıran TFT ekrana yazı yazdırmak istiyorum. İnternette zibilyon kadar STM32F için örnek kod yada driver olsada PIC için bulamadım. Kendi driver ımı kendim yazmakla başa büyük bela aldım . Fakat biraz ilerleme kaydettim. Şöyleki ekranın tamamına istediğim rengi basabiliyorum istediğim noktada 5x8 font kütüphanesinden 1 tane karakter basabiliyorum . Ama bu karakter basma olayını dizi olarak yapamadım . Yani sadece 1 karakter yazabiliyorum .  Bir cümle yazamadım. Kodlar aşşağıda. İlgili arkadaşlar yardımcı olursa çok memnun olurum teşekkürler.

Forumda konuşulan konulardan incelediğim kodlarla şuana kadar dikdörtgen ve çember çizebiliyorum. Fakat bir dizi şeklinde font.h dan dataları alıp yazdıramıyorum .
Kendi yazdığım kodda font5x8 kütüphanesinden çağırdığım dataları ekrana bastırabiliyorum ama 1 adet.
Tek 
void DrawChar(unsigned int X_pos, unsigned int Y_pos, unsigned int ASCII)
{
  	unsigned int i ,j;
	WindowSet(X_pos,X_pos+4,Y_pos,Y_pos+7);
	Write_Command(0x2c);

	for(i=7;i>=0;i--)
	  {
	   for(j=ASCII;j<ASCII+5;j++)
	   {
			if((font5x8[j]>>i)&0x01)
	    	SendData(0x000000);  
		else
			SendData(0xffffff);  	       
	   }
	 }

}

kendi yazdığım fonksiyonu aşşağıdaki gibi diziyi basabilen fonksiyonlara nasıl çevirebilirim? 

void LCD_DrawChar(uint16_t Xpos, uint16_t Ypos, const uint16_t *c)
{
  uint32_t index = 0, i = 0;

  for(index = 0; index <LCD_Currentfonts->Height; index++)
  {
    for(i = 0; i < LCD_Currentfonts->Width; i++)
    {
      if((((c[index]& ((0x80 << ((LCD_Currentfonts->Width / 12 ) * 8 ) ) >> i)) == 0x00) &&(LCD_Currentfonts->Width <= 12))||
        (((c[index] & (0x1 << i)) == 0x00)&&(LCD_Currentfonts->Width > 12 )))
      {
        LCD_WriteData(BackColor);
      }
      else
      {
        LCD_WriteData(TextColor);
      } 
    }
  }
}

hocam pointerları birtürlü düzgün kullanamadım daha basit anlatabilir misiniz mesela  const uint16_t *cc; ne oluyor
