hi shay,

i think you arent looking for a linux splashscreen (as you posted in the NO
OS forum)
so you can upload a picture in the bootloader. im sure theres a option in
the original supervivi, dont know for uboot. must be a "565" image

but here is a little tutorial:

if your os / firmware dont write in the framebuffer the logo will stay at
the lcd "forever"


i need an application that can convert GIF MPEG etc to RGB565 
or samone can help me please how can i write a text on the screan
i know how to show backgraund but not a txt without os.

Best regards.

hi Shay,

Do u have a DVD with you Friendly ARM. There will be ADS1.2, install it and
open the ucos 2 example. Here you will find a file Font_Libs.c. There on
the top u see 

const unsigned short __CHS[]

This is basically CHINESE font. In this file search for __VGA[] keyword. It
is 16 x 8 pixel font. U can also get code from ucos2, how font be written
on the screen. I have printed it with a fine apple background. while cursor
also blink twice in a second and there is no bitmap path error while I
blink cursor or write char or erase char.

 This is the main routine which uses font file as __VGA[]

void Lcd_PutASCII(unsigned int x,unsigned int y,unsigned char ch,unsigned
int c,unsigned int bk_c,unsigned int st)
  unsigned short int i,j;
  unsigned char *pZK,mask,buf;

  pZK = &__VGA[ch*16];
  for( i = 0 ; i < 16 ; i++ )
    mask = 0x80;
    buf = pZK[i];
        for( j = 0 ; j < 8 ; j++ )
            if( buf & mask )
                if( !st )
            mask = mask >> 1;

Best regards.

Very interesting thread and honestly I also do not know how it is possible
to convert GIF MPEG etc to RGB565 but I would love to know it. I do have a
lot of flower pictures because I often use flowers on line free delivery ( ) and every time I receive
flowers I shoot a photo and now I also want to convert them but I do not
know how I can do this.
