Ultrasonic-display-LCD1602
- 調試要求: 1.MCU:AT89S52芯片或AT89C52 2.晶振:12MHz 調試注意: 本程序不帶溫度補償 1.LCD1602液晶屏有顯示後,才接入超聲波模塊。 2.注意超聲波模塊電源的極性。不清楚請參好淘寶的電路圖 3.沒有選用頻率為12MHz晶振,用了別的頻率晶振,單片機定時器的測量值與發出的40KHz頻率脈衝不對。 4.使用者經常誤發出20KHZ脈衝當40KHZ脈衝。(40KHz頻率脈衝,週期25us,占空比為50 = 12.5us)

- 本项目的关键是如何解决高速旋转的电路板如何供电,如何调时的问题。我采用电机电刷的原理,将旋转轴钻空,通过一只插头将电源的从反面引到前面的电路板上,而这个旋转的插头又与固定在背板上的两个铜片接触的。调时的问题有些困难,一是让电路板在旋转前与PC机相接,由电脑传送调时数据,这虽然可行但不方便。还有就是用遥控方法,但此方案在调试方面有很大的困难。 显示方式上,我采用平衡式的两排LED,这除了在旋转时能较好的保持平衡外,主要能利用两边交替显示方式,比单排要快一倍。 本装置不仅是一个时钟,
