控制器应用
使用教程
首先我们先单独学习上层板的应用。
加速度计&陀螺仪
MiniQ 2WD Plus集成加速度计，陀螺仪功能。加速度计&陀螺仪数据的读取是通过IIC获取的，输出的数据是相对于X,Y,Z轴的，如果想要获取相对于坐标系的角度值，则要进行换算。当然，由于加速度计过于灵敏，相信很多小伙伴也遇到这样的困难，模块一点儿小抖动，数据的拨动幅度就很大，这里用一个简单的例子，用陀螺仪的数据进行角度修正，并采用软件滤波器滤波，得到相对稳定的角度数据。实验结果可以通过串口助手观察到。左侧数据代表通过加速度计计算得出的角度，右侧为结合加速度计和陀螺仪最终得出的小车倾斜角度，为了尽量避免负数，我们假定水平放置的MiniQ 2WD Plus上层板角度为90°，使得得到的数据范围在0~180°之间。当然，你也可以修改显示的数据，以及角度范围。

综合应用
miniQ 2WD PLUS & miniQ 2WD
MiniQ 2WD与PLUS上层板是天生的一对。MiniQ 2WD PLUS 和 MiniQ 2WD采用IIC通信，通过Gadgteer连接上下板。MiniQ 2WD PLUS作为IIC主机，MiniQ 2WD作为IIC从机，MiniQ 2WD PLUS通过无线接收命令数据，然后解析，通过IIC发送命令MiniQ 2WD小车底板，作出相应的动作命令。
这里特别说明一下在“运动功能”中，有“巡线模式”、“寻光模式”、“壁障模式”、“遥控模式”，其中的巡线模式中的传感器参数是可以调节的，也就是说，小车可以根据每次使用的巡线场景不同而进行实地调节的。具体操作如下，在进入到巡线模式后，小车并没有直接进入巡线，而是要先进行调节，调节按钮采用底层小车前端的KEY1、KEY2、KEY3三个按钮控制，按下KEY1，对第一个巡线传感器调节（从小车的左侧往右数，第一个巡线传感器），然后KEY2、KEY3是对传感器的值进行调节，不断按下KEY2，直到RGB灯变为红色，（如果接着按KEY3，RGB灯又会变为绿色）按下KEY1确定继续调节第二个。注意：中间那个传感器变为红色后，按下KEY3让它变为绿色，因为我们中间要用来巡黑线的。就这样一次调节完五个传感器。当然，我们在调节的时候，是将小车放在线上的。当五个传感器调节完成后，继续按下KEY1键，小车退出调节模式，而进入正常的巡线模式，如果想再次调节，则再次按下KEY1键，依照前面说的进行调节。遥控模式下使用的遥控器是MiniQ 2WD附带的红外遥控器，使用时“开关”、“VOL+”、“VOL—”、“上一曲”，“下一曲”键分别代表“停止”、“前进”、“后退”、“左转”、“右转”。
下面是样例代码，整个例程还需要直插“LCD12864显示屏扩展板”作为显示器，并使用该显示器扩展版上的集成摇杆进行操作。该样例展示了MiniQ 2WD常用功能：蜂鸣、灯光、巡线、寻光、红外壁障，遥控功能。通过该样例可以更
直观的感受产品的强大以及学习产品的使用方法
注意：程序分两部分，须分别烧录在miniQ 2WD Plus上层板和下层小车中。
