All lcd's support writing pixels. I believe your write_pixel procedure is currently named plot_pixel, but it should be renamed. This procedure is to set one pixel on the screen.
Some don't support reading pixels, and so there should be no procedure defined which is ok. A library can use "if defined(lcd_write_pixel) then" Matt.
