uOLED-128 and sending BMP
PostPosted: Sat Oct 31, 2009 4:38 am     Reply with quote
Trying to output a 256 color BMP converted over by using bmp2c but my problem is, when outputted to the LCD the image is off by 180? degrees and mirrored.

I can fix it by rotating and flipping the image before hand but I'd like a perm fix but I don't know how to do it?

Code:

putc(0x40); // send 'I' command
putc(0);
putc(0);
putc(128);
putc(128);
putc(0x08); //  256color mode, 8bits/1byte per pixel

for(i=0; i<16384; i++)
   putc(rawData1[i]);
}



Here is the rawData1 ...

Code:

for(i=16384; i>0; i++)
   putc(rawData1[i-1]);
}


Is that a quick fix? Or doesn't it flip the image properly?

No, my quick fix is to use an image editor and flip and rotate the image then run it thru bmp2c. It is a hassle to do that everytime I edit the image and save it.
