Description: 学习掌握单总线数字式温度传感器 DS18B20的64位激光ROM码的读出方法。读DS18B20 64位ROM码命令（33h）允许主机直接读出从机的64位ROM代码，而无须执行搜索ROM 过程。如果该命令用于多节点系统，则必然发生数据冲突，因为每个从机设备都会响应该命令。64 位激光ROM 从高位到低位依次由8 位CRC、48 位列号和8 位家族代码(28H)组成。-learning and mastering digital single bus DS18B20 64 laser ROM code to read out the side France. Reading DS18B20 64 orders ROM code (33h) allows mainframe directly read out from the plane of the 64 generation ROM code, and are not required to implement ROM search process. If the order for the multi-node system, the data was inevitable conflict, because each from the plane's equipment will respond to the order. 64 ROM laser from high to low followed by eight CRC, 48 ranks and eight family code (28H).

Description: 基于PIC16F877A的DS18B20一线总线多路测温系统（采用Proteus模拟）。
Proteus模拟电路图＋PIC C语言源程序（MPLAB V8.00）
这可不是用多I/O模拟的多路测温哦！看系统功能：
1）、由一线数据线寄生供电，采用MOSFET强上拉给DQ供电；
2）、上电自动搜索可用的传感器并做CRC校验（实现了Search ROM命令）；
3）、 报警下限可选择；
4）、轮询显示温度，通过LCD1602输出；
5）、 传感器中途拔出或温度越界均报警；
6）、 采用声光报警方式，可做为温度控制信号标志。
-PIC16F877A-based multi-channel bus of DS18B20 line temperature measurement system (using the Proteus simulation). Proteus analog circuit+ PIC C language source code (MPLAB V8.00) This is not using multiple I/O simulation of multi-channel temperature measurement Oh! See system functions: 1) by the parasitic power line data line, using MOSFET strong pull-up power supply to the DQ 2), power-on automatically search for available sensors and do CRC check (to achieve a Search ROM command) 3) alarm limit choice 4), polling shows the temperature, through the LCD1602 output 5), half-way pulled out or the temperature sensors are all cross-border police 6), using sound and light alarm mode can be used as the temperature control signal flags.

Description: DS18B20引脚功能
GND地，DQ数据总线，VDD电源电压
18B20共有三种形式的存储器资源，它们分别是：
ROM 只读存储器，用于存放DS18B20ID编码，其前八位是单线系列编码，后面48位是芯片唯一的序列号，最后8位是以上56位的CRC码。DS18B20共64位ROM
RAM 数据暂存器，数据掉电后丢失，共9个字节，每个字节8位，第1、2个字节是温度转换后的数据值信息，EEPROM 非易失性记忆体，用于存放长期需要保存的数据，上下限温度报警值和校验数据
-DS18B20 Function GND Ground pin, DQ data bus, VDD supply voltage 18B20 There are three forms of memory resources, they are: ROM read-only memory for storing DS18B20ID coding, the top eight single-family is encoded, followed by 48 is the chip serial number only, over the last eight is 56-bit CRC code. DS18B20 total of 64-bit ROM RAM data store, data loss after power-down, a total of 9 bytes, each byte 8-bit, 1, 2 bytes of temperature data converted value information, EEPROM non-volatile volatile memory for storage of long-term need to preserve data, upper and lower temperature alarm and calibration data
