square(frequency, phase) Returns a function whose input is a time (in seconds) and whose output is a point on a square wave. You can create a 440 Hz square wave by mapping a time wave to this square function, using time.map(square(440))

• frequency Frequency of the square wave in Hertz (Hz) or cycles per second.
• phase (optional) Phase shifts the wave to the left or right. A phase of PI shifts the wave a half-cycle to the right. phase can either be a number or it can be a wave, as used in Frequency Modulation.

You can find the code for square in the synthesine library.
