• [MicroPython]TPYBoard智能小车“飞奔的TPYBoard装甲一号”


    智能小车作为现代的新发明,是以后的发展方向,他可以按照预先设定的模式在一个环境里自动的运作,不需要人为的管理,可应用于科学勘探等等的用途。智能小车能够实时显示时间、速度、里程,具有自动寻迹、寻光、避障功能,可程控行驶速度、准确定位停车,远程传输图像等功能。下面带大家做一个智能蓝牙小车,用手机APP来控制小车前进、后退、向左、向右、停止,本次蓝牙小车的设计在于探索蓝牙智能小车的设计理念及设计方法,学习一下PWM控制电机差速来控制小车的方向,下面就动手搞起来吧!!!!!

    1.效果展示

    给大家上视频连接,可以蓝牙控制,可以手柄控制哦

    2.材料准备

    TPYBoard v102 1块
    蓝牙串口模块 1个
    TPYBoard v102小车扩展板(包含4个车轮,4个电机)
    18650电池 2节
    数据线 1条
    杜邦线 若干
    蓝牙APP (http://old.tpyboard.com/download/tool/190.html)

    3.蓝牙模块

    蓝牙( Bluetooth):是一种无线技术标准,可实现固定设备、移动设备和楼宇个人域网之间的短距离数据交换(使用2.4-2.485GHz的ISM波段的UHF无线电波)。
    我们在此使用的蓝牙模块(HC-06)已经在内部实现了蓝牙协议,不用我们再去自己开发调试协议。这类模块一般都是借助于串口协议通信,因此我们只需借助串口将我们需要发送的数据发送给蓝牙模块,蓝牙模块会自动将数据通过蓝牙协议发送给配对好的蓝牙设备。

     

    4.单片机-TPYBoard v102

    TPYBoard v102 是遵循MIT协议,由TurnipSmart公司制作的一款MicroPython开发板,它基于STM32F405单片机,通过USB接口进行数据传输。该开发板内置4个LED灯、一个加速度传感器,可在3V-10V之间的电压正常工作。让你会Python就能做极客, 用Python控制硬件,支持Python语言的开发板。比树莓派更小巧,更简单,更便宜,比Arduino更强大,更加容易编程。

     

    小车扩展板
    以TPYBoard v102开发板为主控板,小车扩展板具有四路PWM调速电机、8个可控LED、1个蜂鸣器、5路舵机接口、1个蓝牙接口、1个PS2无线接口、引出TPYBoard v102开发板全部针脚,可装载循迹模块、超声波模块、机械手臂、红外接收头,兼容入门级电机和专业级电机,两节18650单独供电。

     

    源代码
    我们只需要把TPYBoard v102 插小车扩展板上,把蓝牙模块插上,把程序写入就行,下面是main.py源程序
