Im trying to invert characters on this Nokia-LCD
it inverts the whole Display,but I only want to invert some sentences or chars like on this picture
In the german section of this forum I got this hint :
" In the program you have a variable who store the value of every char (5 bytes). This function writes these 5 bytes in the RAM and then transfer it to the display
Try to create (copy) a function who invert this value. Use for this a XOR with 255."
Im sorry, but Im not that C-Pro and want to ask if anyone can explain me that with some democode or something...
