Description: 1.MCU:AT89S52芯片或AT89C52
2.晶振:12MHz
本程序带温度补偿，采用DS18B20测量温度
1.LCD1602液晶屏有显示后，才接入超声波模块。
2.注意超声波模块电源的极性。不清楚请参好淘宝的电路图
3.没有选用频率为12MHz晶振，用了别的频率晶振,单片机定时器的测量值与
发出的40KHz频率脉冲不对。
4.使用者经常误发出20KHZ脉冲当40KHZ脉冲。（40KHz频率脉冲，周期25us,
占空比为50 = 12.5us）
5.如果是用开发板调超声波模块,请检查开发板上的电路是否与超声波模块的
控制脚复用了, 若复用了,请通过跳线分开发板上的电路。
6如果使用的是万用板，请确定单片机的复位电路和晶振电路是否正常，同时
单片机的31脚（EA）记得 接高电平。-1.MCU:AT89S52 chip or AT89C52
2: 12MHz crystal
This procedure with temperature compensation, temperature measurement using DS18B20
1.LCD1602 LCD display, ultrasonic module to access.
2 note the polarity ultrasonic module power supply. Not clear please reference the good Taobao circuit diagram
3 does not use frequency of 12MHz crystal, with other frequency oscillator, timer value and measurement
The frequency of 40KHz pulses emitted by the wrong.
4 user often mistakenly sent 20KHZ pulse when the 40KHZ pulse. (40KHz pulse frequency, cycle 25us,
The duty cycle is 50 = 12.5us)
5 if it is adjustable ultrasonic module development board, please check whether the circuit development board and the ultrasonic module
Control pin multiplexing, if reuse, please by jumper circuit development board.
6 if you are using a universal board, please make sure to reset circuit and oscillator circuit of MCU is normal, and at the same time
MCU 31 feet (EA) remember with the high level. Platform: |
