10、AB键与玫瑰曲线
玫瑰曲线，按A加1，按B开始

玫瑰曲线，基本的意思是：平面内，围绕某一中心点平均分布整数个正弦花瓣的曲线。数学公式是：ρ=a*sin(nθ),a为定长,n为整数（不一定是花瓣数）。

由于这个图形不是由直线组成，所以，掌控板上的所有绘图函数均无法使用，只能使用其中的像素点显示功能。命令如下：
display.pixel(50,0,1)
这个命令中：display.pixel(x, y [,c ]) x , y 为点坐标(x,y)。当如果未给出c，则获取指定像素的颜色值。如果给出c，则将指定的像素设置为给定的颜色，由于掌控板用的是黑白屏幕，所以用1代表点亮就可以了。

12、AB按键秒表计时器

秒表主要是用来统计秒数的。它有一般有两个按键。A键和B键。

第一次按下A键时，开始计时。

第二次按下A键时，暂停计时。

再按下A键时，继续上一步暂停的计时。

按下B键，归零。
