四、模块命令介绍：
模块目前支持4种命令。命令格式为【cmd】【x】【y】【z】【r】【g】【b】【rsv】 其中cmd为命令，X,Y,Z分别代表三个轴的坐标值，r，g，b分别代表该坐标的红绿蓝三个颜色值，rsv为保留字节。 命令0×01：将整个光立方设置成某种颜色，X,Y,Z无效。 命令0×02：设置演示模式，X代表模式,Y,Z无效，r，g，b，rsv代表循环次数。目前3种演示模式。 命令0×03：设置某个点的颜色，X,Y,Z分别代表三个轴的坐标，r，g，b分别代表该坐标的红绿蓝三个颜色值。 命令0×04：从坐标（0,0,0）开始发送数据，，X,Y,Z，r，g，b，rsv无效。命令发送完成后后面跟着的是点的颜色数据。
