Very nice. I ended up destroying the connector on my 6100. Watch if you try to unplug it from the board. It's definitely a pretty little LCD and not too hard to develop for. Main problem I've seen is the complaints about the different versions.

If anyone finds a really cheap source, I might get another one or two, but right now I haven't found a need to replace my old broken one.

I'm tired like crazy..I'll post links in a little bit

Ok im working in VB6 and so far i can open a image and get the RGB of each pixel. Im not sure if im converting it correctly since i havnt tried it yet. But since the RGB is 4-4-4 for this LCD to be 12bit .... Im diving the 255,255,255 by 17 each this way the max of 255 is turned into 15(F)(1111) which is 4 bits.

I hope this works heh.. Now i have to code the creation on data bytes. I need to connect every 2 parts together to make one byte and if then append a 0 to the end if need be (odd amount of pixel data)

Wish me luck. Remember all the code and stuff will be shared and posted when complete or if i quite (most likely complete :D )

RGB and black? What the heck colour pallet are you using?
RGB at all FFs is white, RGB at all 00s is black, if you have a fourth colour it's either an alpha channel a mask or you badly mistyped something.

heh i mean im trying RED, GREEN, BLUE, WHITE and BLACK color image...


I ran into a issue::
MAX = unsigned long
the width and height = unsigned char
Code:
    max = width * height;

My problem is if width = 50 and height = 50 max should = 2500 but it = 196

any thoughts????

dude for this display it uses 4 bit color for each RGB so
RED = 4 bit
GREEN = 4 bit
BLUE = 4 bit

Now if pixel 1 is solid red you get F0,0
and if pixel 2 is solid blue you get 0F,0

but as decimals so thats.... 240,0,240 the way the lcd works is it will read the 2 bytes like

RRRRGGGG,BBBBRRRR,GGGGBBBB = 11110000,0000,11110000

you see?

That makes even less sense atom....
RGB....
All 00s == black. All FFs == white. There should be no separate bytes other than R G and B.

hey guys this is killing me:

Code:
void LCDWriteBMP(unsigned rom char *bmp, unsigned char x, unsigned char y, unsigned char width, unsigned char height) {
unsigned int j;
unsigned int maxPix;
unsigned int xmin, xmax, ymin, ymax;
unsigned int i;

    maxPix = 0;

    //maxPix = (width * height);
    for(j = 0; j < height; j++) {
        maxPix += width;
    }

    xmin = x;
    xmax = x + width;
    ymin = y;
    ymax = y + height;

    LCDCommand(PASETP);
    LCDData(ymin);
    LCDData(ymax);

    LCDCommand(CASETP);
    LCDData(xmin);
    LCDData(xmax);

    LCDCommand(RAMWRP);

    for(j = 0; j < maxPix; j++) {
        LCDData(*bmp++);
    }
}

The above might work well... I call it like:

LCDWriteBMP(bmp444,20,20,50,50);

for some reason the values are mixed up or wrong..

The calculation is being done in unsigned char (i.e. multiples of 256 are being dropped in the result), put another way:

2500 = hex 9C4

Hex C4 = 196

You need to force the calculation to be done in unsigned long
max = width;
max = max * height;
would probably do it or you could probably use explicit type casts.

the issue was it wasnt getting the data from the call but i fixed it somewhat;

Code:
    width = *bmp++;
    height = *bmp++;

    for(j = 0; j < height; j++) {
        maxPix += width;
    }

but ill try your suggestion for the math tho

UPDATE:

Code:
    width = *bmp++;
    height = *bmp++;

    maxPix = height;
    maxPix = maxPix * width;

Works well! thanks
