五、原理图和接线说明
1、原理图 2、接线说明
需要注意的是系统连接完成后必须用TypeC口供电否则用下载器供电不能同时带起来LCD屏和舵机会出现LCD屏白屏闪烁的问题。 LCD显示引脚 VCC -- 3.3V GND -- GND CS -- PB11 Reset -- PB12 DC -- PB10 SDI -- PB15 SCK -- PB13 LED -- PB9 HC-SR04引脚 VCC -- 5.0V GND -- GND Trig -- PA5 Echo -- PA0 SG90引脚 VCC -- 5.0V GND -- GND PWM信号线 -- PA6 六、软件设计过程
1、cubemx配置
1时钟和系统 2GPIO配置PA5用于输出超声波传感器的发射信号PB9、PB10、PB11、PB12用于LCD屏的控制 3定时器配置TIM1用于产生微秒延时产生超声波的发射信号TIM2用于捕获超声波收到的信号从而计算出距离物体的距离TIM3用于产生PWM波用于控制舵机的转动 数据参数意义 此时产生PWM波形频率72M / (719 1)/ (19991) 50Hz 定时器周期1/50 20ms
4SPI设置 用于与LCD屏的通讯 5时钟树 2、程序代码 1main函数
