squarewave8()

LIB8STATIC uint8_t squarewave8	(	uint8_t	in,
		uint8_t	pulsewidth = 128 )

Square wave generator.

Useful for turning a one-byte ever-increasing value into a one-byte value that is either 0 or 255. The width of the output "pulse" is determined by the pulsewidth argument:

if pulsewidth is 255, output is always 255.
if pulsewidth < 255, then
  if input < pulsewidth  then output is 255
  if input >= pulsewidth then output is 0

The output looking like:

255   +--pulsewidth--+
 .    |              |
 0    0              +--------(256-pulsewidth)--------

Parameters

in	input value
pulsewidth	width of the output pulse

Returns

square wave output
