Hey guys,

I'm at the moment on an internship and I set myself the task to draw something on the LCD-Display.
The problem is that I'm totally new in programming a board. I tried to use the driver included in the test software, but it doesn't work.
I used the idea of the driver and tried to build my own functions:

typedef volatile unsigned short REG16;
#define LCD_IR(baseAddr) (*((REG16 *)(baseAddr)))
#define LCD_D(baseAddr) (*((REG16 *)((unsigned int)(baseAddr) + (1 << 1))))

//defintion of R..H


void WriteReg( void *pLcdBase, int reg, int data)
{

LCD_IR(pLcdBase) = reg;
LCD_D(pLcdBase) = data;
}

void LCD_Initialize ( void *pLcdBase ) {
WriteReg(pLcdBase, R19H, 0x49); // OSCADJ=10 0000, OSD_EN=1 //60Hz
WriteReg(pLcdBase, R93H, 0x0C); // RADJ=1100

// Power on flow
WriteReg(pLcdBase, R44H, 0x4D); // VCM=100 1101
WriteReg(pLcdBase, R45H, 0x11); // VDV=1 0001
WriteReg(pLcdBase, R20H, 0x40); // BT=0100
WriteReg(pLcdBase, R1DH, 0x07); // VC1=111
WriteReg(pLcdBase, R1EH, 0x00); // VC3=000
WriteReg(pLcdBase, R1FH, 0x04); // VRH=0100

WriteReg(pLcdBase, R1CH, 0x04); // AP=100
WriteReg(pLcdBase, R1BH, 0x10); // GASENB=0, PON=1, DK=0, XDK=0, DDVDH_TRI=0, STB=0
delay(50);

WriteReg(pLcdBase, R43H, 0x80); // Set VCOMG=1
delay(50);

// Gamma for CMO 2.8
WriteReg(pLcdBase, R46H, 0x95);
WriteReg(pLcdBase, R47H, 0x51);
WriteReg(pLcdBase, R48H, 0x00);
WriteReg(pLcdBase, R49H, 0x36);
WriteReg(pLcdBase, R4AH, 0x11);
WriteReg(pLcdBase, R4BH, 0x66);
WriteReg(pLcdBase, R4CH, 0x14);
WriteReg(pLcdBase, R4DH, 0x77);
WriteReg(pLcdBase, R4EH, 0x13);
WriteReg(pLcdBase, R4FH, 0x4C);
WriteReg(pLcdBase, R50H, 0x46);
WriteReg(pLcdBase, R51H, 0x46);

//240x320 window setting
WriteReg(pLcdBase, R02H, 0x00); // Column address start2
WriteReg(pLcdBase, R03H, 0x00); // Column address start1
WriteReg(pLcdBase, R04H, 0x00); // Column address end2
WriteReg(pLcdBase, R05H, 0xEF); // Column address end1
WriteReg(pLcdBase, R06H, 0x00); // Row address start2
WriteReg(pLcdBase, R07H, 0x00); // Row address start1
WriteReg(pLcdBase, R08H, 0x01); // Row address end2
WriteReg(pLcdBase, R09H, 0x3F); // Row address end1

// Display Setting
WriteReg(pLcdBase, R01H, 0x06); // IDMON=0, INVON=1, NORON=1, PTLON=0
WriteReg(pLcdBase, R16H, 0xC8); // MY=1, MX=1, MV=0, BGR=1
WriteReg(pLcdBase, R23H, 0x95); // N_DC=1001 0101
WriteReg(pLcdBase, R24H, 0x95); // P_DC=1001 0101
WriteReg(pLcdBase, R25H, 0xFF); // I_DC=1111 1111
WriteReg(pLcdBase, R27H, 0x06); // N_BP=0000 0110
WriteReg(pLcdBase, R28H, 0x06); // N_FP=0000 0110
WriteReg(pLcdBase, R29H, 0x06); // P_BP=0000 0110
WriteReg(pLcdBase, R2AH, 0x06); // P_FP=0000 0110
WriteReg(pLcdBase, R2CH, 0x06); // I_BP=0000 0110
WriteReg(pLcdBase, R2DH, 0x06); // I_FP=0000 0110
WriteReg(pLcdBase, R3AH, 0x01); // N_RTN=0000, N_NW=001
WriteReg(pLcdBase, R3BH, 0x01); // P_RTN=0000, P_NW=001
WriteReg(pLcdBase, R3CH, 0xF0); // I_RTN=1111, I_NW=000
WriteReg(pLcdBase, R3DH, 0x00); // DIV=00
WriteReg(pLcdBase, R3EH, 0x38); // SON=38h
WriteReg(pLcdBase, R40H, 0x0F); // GDON=0Fh
WriteReg(pLcdBase, R41H, 0xF0); // GDOF=F0h
}

void LCD_WriteRAM_Prepare( void *pLcdBase )
{
LCD_IR(pLcdBase) = R22H;
}


void LCD_WriteRAM( void *pLcdBase, unsigned short color24 )
{
unsigned short color16 = RGB24ToRGB16(color24);
LCD_D(pLcdBase) = color16;
}



and I call it this way:

#define LCD_BASE_ADDR 0x62000000


LCD_Initialize((void *)LCD_BASE_ADDR);
LCD_On((void *)LCD_BASE_ADDR);

LCD_SetCursor((void *)LCD_BASE_ADDR, 0, 0);
LCD_WriteRAM_Prepare((void *)LCD_BASE_ADDR);
for (i = 0; i < (240 * 20); i++)
{
LCD_WriteRAM((void *)LCD_BASE_ADDR, 0xFF0000);
}



And nothing happens... what am I doing wrong?
