### Rainbow ### Rainbow
Displays a simple moving rainbow pattern over a strip of fixed length. Displays a simple moving rainbow pattern over a strip of fixed length.
Make sure the '''F_CLK''' is set to the actual frequency present on the hardware for '''clk'''. Make sure the `F_CLK` is set to the actual frequency present on the hardware for `clk`.
To set the length, change the '''LENGTH''' constant. To change the speed of the animation, change the '''F_SYSTICK''' constant. To change the length of one iteration of the rainbow, set the '''INCREMENT''' constant. To change the maximum brightness, change the '''PIXDATA_MAX''' constant while making sure that it is a multiple of '''INCREMENT'''. To set the length, change the `LENGTH` constant.
