利用单片机设计一个显示温度的系统，主要采用的是静态显示的方式...

采用80C51单片机为控制核心，利用超声波传感器检测道路上的障碍，控制电动小汽车的自动避障，快慢速行驶，以及自动停车，并可以自动记录时间、里程和速度，自动寻迹和寻光功能。-80C51 single-chip microcomputer used for the control of the core, the use of ultrasonic sensors detect obstacles on the road, control of electric cars automatic obstacle avoidance, fast low traffic speeds, as well as the automatic parking, and can automatically record time, mileage and speed, automatic track finding and searching optical function.

C51库只提供长整形乘法，对于超过长整形的计算只能自己编辑软件。-C51 for only provide long-plastic multiplication, long plastic over the calculation only their own editing software.

是protel的讲义，应该有利于大家的学习-Yes protel lectures, should be conducive to our learning

通过DS18B20读取温度（范围-55C~125C，精确到小数点后一位），通过4位数码管显示出来。 当温度为正且百位为零时，不显示，当温度为负时百位显负号。当温度百位和十位都为0时0都不显示。-Read through the DS18B20 temperature (range-55C ~ 125C, accurate to one decimal), through four digital tube display. When the temperature is zero and 100, do not show, when the temperature is significantly negative at minus 100. When the temperature is 100 and 10 are not displayed 0:00.

method to setup svn, may be can help to you

DAC1230是一个12位的模数转换的芯片!而使用时候是在8位的单片机上运行,所以需要注意高四位和低八位的写入时序-DAC1230 is a 12-bit analog-digital conversion chips! Use of time in the 8-bit single-chip run, so it is necessary to pay attention to the high four and low eight write timing

利用430做的一个产生时钟脉冲的程序，可以调的！-430 make use of a clock pulse generated procedures, you can tune in!

是一个在液晶上画斜线的C51的程序，希望对大家有帮助！-is a picture of the LCD slash the C51 process, we want to help!
