用cvavr自带的库函数做的ds18b20带lcd显示的程序，时序很准，可传输400多米-Built-in library functions with cvavr do ds18b20 with lcd display program, timing is very accurate and can be transmitted more than 400 meters

AVR，温度计加时钟芯片，有1302和PCF8563,有PCB和原理图及程序。使用18b20测温。编程环境为CVAVR。一个产品。-use ds1302 and pcf8563 with AVR chip to measure temperature and display time.

这是我用mega16调的ds1302程序代码，编译软件用的cvavr，希望对大家有帮助-This is my tune with mega16 ds1302 code, the compiler software used cvavr, we hope to help
