Matrix库的几个函数
基本用法，仅限像素
Matrix myLeds = Matrix（DIN，CLK，LOAD，numChips）;
使用您选择的名称创建Matrix对象的实例。DIN，CLK和LOAD是连接这些信号的引脚号。如果连接了多个单独连接的MAX7219芯片，则可以创建多个对象。
myLeds。clear（）;
清除整个显示屏。
myLeds。setBrightness（15）;
设置显示亮度，从0到15（最亮）。
myLeds。write（x，y，value）;
更改单个像素。对于关闭，值应为LOW，对于on，值应为HIGH。
基本用法，使用Sprite
Sprite myIcon = Sprite（宽度，高度，B11000，B11000，B11111，B11111）;
创建一个精灵对象。您可以根据需要创建任意数量的精灵，每个精灵都有一个唯一的名称。宽度应与每个数据值中的位数匹配，高度应与数据值的数量匹配。
myLeds。write（x，y，myIcon）;
在显示屏上绘制一个闪烁的精灵。
Sprite库允许创建与Matrix库一起使用的图像精灵
Sprite
启动LCD库。
width（）
返回精灵的宽度（以像素为单位）。
height（）
返回精灵的高度（以像素为单位）。
write（）
将数据写入精灵的x，y位置。
read（）
返回存储在sprite的x，y位置的数据。
