I have a LM6733 LCD with touch screen which has a SED1330 controller. I'm looking into using a PIC24 to send commands/text to the controller, but my issue is with the programing. I have done some programing with the HD44780U so I'm kinda familiar with the little guys.

Here are the links to the LM6733 Module specs and the SED1330 Technical Manual.

I haven't been able to find any initialization code, in C, to start with and I'm trying to avoid having to start everything from scratch, but if that is what I have to do then I will. Any info/help will be appreciated.

So I have the following code to try and display a few lines on LM6733 LCD module, but I have not been lucky at it. Any help will be appreciated.

Code: 
void GLCD_Init(void)
{	
	Delay( Delay_50mS_Cnt );
  		lcdSndCmd(SYSTEM_SET);
  			lcdSndData(0x38);
  			lcdSndData(0x87); 		//Char width	           
  			lcdSndData(0x07);   			// Char height  	        	
 			lcdSndData(0x3F);     			// Chars per row     
  			lcdSndData(0x49);    			// Frame Frequency control 
 			lcdSndData(0x7F);          			// Lines per Graphic Screen
  			lcdSndData(0x80);      			// Virtual Screen Width low byte
  			lcdSndData(0x00);                   				// Virtual Screen Width high byte 
  
  		lcdSndCmd(SCROLL);
  			lcdSndData(0x00);   // P1
  			lcdSndData(0x00);   // P2
  			lcdSndData(0x40); 	// P3
  			lcdSndData(0x00);   // P4
  			lcdSndData(0x10);   // P5
  			lcdSndData(0x40);   // P6
			lcdSndData(0x00);   // P7
  			lcdSndData(0x04);   // P8
  			lcdSndData(0x00);   // P9 
			lcdSndData(0x30);	// P10

  		lcdSndCmd(HDOT_SCR);     
  			lcdSndData(0x5A);   // P1
  			lcdSndData(0x00);   // P2

  		lcdSndCmd(OVLAY);
  			lcdSndData(0x01); 	// P1

  		lcdSndCmd(DISP_DIS); 
			lcdSndData(0x56); 	// P1

		lcdSndCmd(CSRW); 
  			lcdSndData(0x00);   // P1       
  			lcdSndData(0x00);  	// P2

  		lcdSndCmd(CSR_FORM);
  			lcdSndData(0x04);   // P1
  			lcdSndData(0x86);   // P2      

 		lcdSndCmd(DISP_EN);     /* Display on*/
  			lcdSndData(0x14);          /* Do not switch on Cursor ( messes up Graphics ) */

  		lcdSndCmd(CSR_DIR_R);     /* shift cursor right */
  
  		lcdSndCmd(MWRITE);           
  			lcdSndData(0x20);
			lcdSndData(0x45);
			lcdSndData(0x50);
			lcdSndData(0x53);
}
