Hi Martin,
I've not used the TS-7KV (I'm using a TS-7300).
The 7300 uses a 15-bit color scheme - RRRRRGGGGTBBBB - packed into a
16-bit value. The 'T' bit is optionally used a transparent toggle bit
when using some blit operations. I'm fairly sure the color is the
same for the 7KV, but I'm not sure about the transparent bit.
>From memory (for the TS-7300), I had to map the VIDCTRL and screen
map as two different locations. The screen is simply a 800x600 or
640x480 array of 16-bit values.
With regard to the VIDCTRL offsets, I'd have to look at my code. But
you have to be careful about the size of the register allocated by
mmap Reg[4] would move depending on the assigned size.
I'll see if I can dig out another example and post it in the files
section - I have a couple of weeks off but no board to test it on...
Regards,
PJE
