I have been using the EB043 glcd, with no problems.
but now I wish to dispay an image on the LCD. what would be the process for this ?(132x132)
Im using an 18f4550(mchpusb) but I figure the size of the array would be to large so I think I would have to use an MMC/sd card for the DATA.
I thought I could plot each pixel, but how to get the colour right has me stuffed. The programs on the net I found to convert pictures seam to have 1 number (ie 0x00) per pixel. ?
here is an example of a 16x16 pixel bitmap?

Code: Select all

#define image_width (16)
#define image_height (16)


unsigned char bitmap[]= 
{
0xE0, 0xE0, 0xE0, 0xE0, 0xE0, 0xE0, 0xE0, 0xE0, 0xE0, 0xE0, 0xE0, 0xE0, 0xE0, 0xE0, 0xE0, 0xE0,

Is something like this possible, or am I look at this the wrong way
Anyone managed to display a picture on a glcd using flowcode?. If you have any ideas or input PLEASE POST.

OK OK
So I found the C code examples. and have been playing around with Lcd_Drawimage. I changed it to make 2 different coloured lines on the lcd.

Code: Select all

void Lcd_drawimage (char X1, char Y1)
{
	char i;
	Lcd_window(X1,Y1,X1+129,Y1+129);

	for (i=0;i<130;i++)			//1
	{
		Lcd_sendbyte(PARAM, 0xFF);//white
	}
	for (i=0;i<130;i++)
	{
		Lcd_sendbyte(PARAM, 0X00);//black
	}
	for (i=0;i<130;i++)
	{
		Lcd_sendbyte(PARAM, 0xFF);//white
	}
	for (i=0;i<130;i++)
	{
		Lcd_sendbyte(PARAM, 0X00);//black
	}


}

All I have to do now is replace the colour with the image info. How do I do this, some kind of array?
Like the charaters?

EDIT
Alright I got the picture sorted
here is a simple Picture (Actualy from a descktop Icon).

: nostromo1a.jpg (771 Bytes) Viewed 1514 times

The convertor said it was 16x16 but I could only get it to look right on 15x15.
the picture data is char bmp []
Snipet from GFX_LCD_functions.c

	char i;
	char j=0;
	Lcd_window(X1,Y1,X1+15,Y1+15);

	for (i=0;i<255;i++)
	

	{
		
		Lcd_sendbyte(PARAM, bmp[j++]);       // send data / increment bmp
	}
	for (i=0;i<4;i++)                                                // was missing a few pixels had to add this
	

	{
		
		Lcd_sendbyte(PARAM, bmp[j++]); .
	}

}

So because 16x16 is about the limit of the micro, how do I stream the info from say a MMC Card. I have a MMC card reader I Made and it works perfectly.
here is my demo code in full.
