I am trying to use the color keying feature of the K70 LCDC without success. I am using the tower system, I can display things on the LCD (our own) without any issues, using the graphics window and background.
What I have is a graphics window of 100 lines with a group of red lines in the middle, from my understanding if I enable color keying correctly these red lines should become transparent... is this correct? If so then below is the code I am using to enable color keying:
// set LCD graphic window control
LCDC_LGWCR_GWAV(0x9f) | // alpha-transparent value (0xFF is opaque)
LCDC_LGWCR_GWCKE_MASK | // Colour Keying enable
LCDC_LGWCR_GWCKR(0x3f) | // Red colour keying
If anybody has used color keying successfully I would appreciate any help or ideas as to why mine doesn't. Apologies if I have missed any information that may help.
