"""
pyboard interface

This module provides the Pyboard class, used to communicate with and
control the pyboard over a serial USB connection.

Example usage:

let sectorArcPath = function(x,y,r,startAngle,endAngle){
    endAngle = startAngle + ((endAngle-startAngle)%360);
    let startX, startY, endX, endY;
    startX = x+r*Math.sin(startAngle*Math.PI/180);
    startY = y-r*Math.cos(startAngle*Math.PI/180);
    endX = x+r*Math.sin(endAngle*Math.PI/180);
    endY = y-r*Math.cos(endAngle*Math.PI/180);
    let b= startY < endY ? 1 : 0;
    let obtuse = Math.abs(startAngle-endAngle)>180?1:0;
    let startSmaller = startAngle<endAngle ? 1 : 0;
