HI I'm using like the following code.

void InitQQVGA() { QQVGA RGB444 WriteReg(REG_CLKRC,0x80); WriteReg(REG_COM11,0x0A) ; WriteReg(REG_TSLB,0x04); WriteReg(REG_COM7,0x04) ; WriteReg(REG_RGB444, 0x02); WriteReg(REG_COM15, 0xd0); WriteReg(REG_HSTART,0x16) ; WriteReg(REG_HSTOP,0x04) ; WriteReg(REG_HREF,0x24) ; WriteReg(REG_VSTART,0x02) ; WriteReg(REG_VSTOP,0x7a) ; WriteReg(REG_VREF,0x0a) ; WriteReg(REG_COM10,0x02) ; WriteReg(REG_COM3, 0x04); WriteReg(REG_COM14, 0x1a); WriteReg(0x72, 0x22); WriteReg(0x73, 0xf2);

COLOR SETTING WriteReg(0x4f,0x80); WriteReg(0x50,0x80); WriteReg(0x51,0x00); WriteReg(0x52,0x22); WriteReg(0x53,0x5e); WriteReg(0x54,0x80); WriteReg(0x56,0x40); WriteReg(0x58,0x9e); WriteReg(0x59,0x88); WriteReg(0x5a,0x88); WriteReg(0x5b,0x44); WriteReg(0x5c,0x67); WriteReg(0x5d,0x49); WriteReg(0x5e,0x0e); WriteReg(0x69,0x00); WriteReg(0x6a,0x40); WriteReg(0x6b,0x0a); WriteReg(0x6c,0x0a); WriteReg(0x6d,0x55); WriteReg(0x6e,0x11); WriteReg(0x6f,0x9f);
