I'm trying to send a bitmap to an LCD and have not been successful yet and looking to see if someone can give me a hand here.

PIC18F452 is being used.
SED1330 LCD controller.

Code: 
unsigned rom char logo1_bmp [1188] =
{    0x00, 0x00, 0x00, 0x00, 0x00, 0x1c, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,

Re: sending bitmap to LCD

Hi

can you also post the function lcdSendData();

right now it isnt very clear because lcdSendData() must accept a byte from the saved bmp array.

lcdSendData((bmp[variable]); is a more likely usage.

if you can post some more details of the code you are trying to use, I might be able to help you.
 

Re: sending bitmap to LCD

Here it is:

Code: 
void lcdSendCommand(unsigned  char command )
{
   	GLCD_RD = 1;
    GLCD_COMMAND = 1;
    GLCD_CS = 0;
    GLCD_WR = 0;
    GLCD_DATA  = command;
Delay1TCY();
Delay1TCY();
    GLCD_CS = 1;
    GLCD_WR = 1;
    GLCD_COMMAND = 0;
}

/******************************
*   Send Data to Controller   *
*******************************/

void lcdSendData(unsigned char value )
{ 
	GLCD_RD = 1;
    GLCD_COMMAND = 0;
    GLCD_CS = 0;
    GLCD_WR = 0;
    GLCD_DATA    = value;
Delay1TCY();
Delay1TCY();
    GLCD_CS = 1;
    GLCD_WR = 1;
}
 

Re: sending bitmap to LCD

Hi

Before trying to write to LCD - check that LCD controller work as expected.

Try writing and reading from a scrap register(GPIO register)

Also test whether the PLL lock to programed frequency

try writing a single pixel and look for it on the LCD

Whether you pass all this test - your LCD is ready to accept data for display

All the best

Re: sending bitmap to LCD

try and change lcdSendData((bmp+j+(40*i)));
to:
lcdSendData((bmp[j+(width*i)]);

or

lcdSendData((bmp[i+(width*j)]);

I am not sure on how you want to display the image.
