MSP-EXP432P4111: Can nout initialize the LCD ST7066U

Part Number: MSP-EXP432P4111

Hi,

I am trying to use an character LCD which controlled by ST7066U. I have MSP-EXP432P4111 and i am using IAR Workbench as compiler.I only have backlight and nothing more. Here is my code.

P4-Pin-0,1,2,3,5,6,6,7 are my data connections. P5 Pin0 is RS, P5 Pin1 is Enable. R/W is connected to ground. Thank you.

unsigned char CGRAM1[8] ={0x04,0x0E,0x15,0x04,0x04,0x04,0x04,0x04,};  
unsigned char CGRAM2[8] ={0x04,0x04,0x04,0x04,0x04,0x15,0x0e,0x04,};  
unsigned char CGRAM3[8] ={0x1f,0x11,0x11,0x11,0x11,0x11,0x11,0x1f,};  
unsigned char CGRAM4[8] ={0x0a,0x15,0x0a,0x15,0x0a,0x15,0x0a,0x15,};

	WriteIns(0x48);	  
	for(j = 0;j<8;j++){
	   WriteData(CGRAM4[j]); //data write to CGRAM
	}
}
