D4D_ORIENT_PORTRAIT180 buffer shifted by one line

[faghio]

It looks like line 234 of d4d_lcd_frame_buffer.c:

win_const1 = (signed long)(p_fbDesc->fb_start_addr + (p_fbDesc->lcd_x_max * win_x + p_fbDesc->lcd_x_max - win_y) * bpp_byte);

needs to be changed into:

win_const1 = (signed long)(p_fbDesc->fb_start_addr + (p_fbDesc->lcd_x_max * win_x + p_fbDesc->lcd_x_max - win_y - 1) * bpp_byte);

(-1 added) otherwise an LCD used with D4D_ORIENT_PORTRAIT180 orientation will show the first horizontal line of screen on the bottom (the whole screen is "rolled" up by 1 line).

Do you agree?

I have to be :-).

This orientation I never tested. If you can create push request, with the change.

Thank you Petr

Sorry I didn't finish my sentence :-)

So:

This orientation I never tested. If you can create push request, with the change_, then I will be more than happy._

Thank you
