/**************************************************************** 程序功能 将超声波模块、舵机安装好并连接好杜邦线。智能小车上电后,按下开发 板启动按键(靠近电源开关那个)小车开始避障碍运动。同时测到的距离 值会在OLED中显示出来。 接线说明: 电机驱动线: 开发板的PA2接小车底盘的M6 开发板的PA3接小车底盘的M5 开发板的PA4接小车底盘的M4 开发板的PA5接小车底盘的M3 开发板的PA6接小车底盘的M2 开发板的PA7接小车底盘的M1 超声波模块接线: 超声波模块的VCC接开发板的5V 超声波模块的GND接开发板的GND 超声波模块的Trig接开发板的PB1 超声波模块的Echo接开发板的PB0 舵机接线: 将舵机线接到小车底盘的舵机接口上(注意方向,舵机棕线是GND,红线是VCC, 橙线是信号线。它们分别对应小车底盘舵机接口上的GND,5V和S)。另外,舵机 的信号线需要一条单独的杜邦线连接到开发板的PA0。 电源线: 开发板的5V接小车底盘的5V 开发板的GND接小车底盘的GND 红外避障信号线: 开发板的PA13接小车底盘的H3 开发板的PA14接小车底盘的H4 (本实验采用红外避障作为超声波避障的辅助,所以红外避障信号线也要 连接)
