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.

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: 8位单片机与DS18B20并行双向通信。
Quartus II 8.1项目工程文件.
主源程序文件为DS18B20.v,里面有详细注解。
例子：
DS18B20 数据地址 0xf000（ROM=0） DS18B20 ROM指令地址 0xf001（ROM=1）
外部电源供电且只有一DS18B20的读取法：
发送CC到0xf001,
等待busy=0说明器件已准备好,
读0xf001的Bit1=1说明存在器件,Bit0=1为控制忙(可以省略此步）
发送44到0xf000,
等待busy=0，
发送CC到0xf001，
等待busy=0，
发送BE到0xf000，
等待busy=0，
空读一次，
等待busy=0，
然后读到的就是DS18B20内部数据了.读一次必须等待busy=0，否则控制器将拒绝所有操作。
搜索ROM：
发送F0或EC到0xf001,
等待busy=0说明器件已准备好,
读0xf001的Bit1=1说明存在器件,Bit0=1为控制忙(可以省略此步）
空读0xf000，（第1次）
等待busy=0，
读0xf000，Bit0是DS18B20发送位的信息，Bit1为DS18B20发送位的补码信息
等待busy=0，
写0xf000，内容为路径。
等待busy=0，
。。。。。。
空读0xf000，（第64次）
等待busy=0，
读0xf000，Bit0是DS18B20发送位的信息，Bit1为DS18B20发送位的补码信息
等待busy=0，
写0xf000，内容为路径。
等待busy=0，
结束
-8-bit microcontroller with DS18B20 parallel two-way communication.
Quartus II 8.1 Project documents.
Primary source documents DS18B20.v, which detailed notes.
Example:
DS18B20 Data Address 0xf000 (ROM = 0) DS18B20 ROM instruction address 0xf001 (ROM = 1)
An external power supply and only a DS18B20 read method:
Send CC to 0xf001,
Wait for busy = 0 shows the device is ready,
Read 0xf001 the existence of Bit1 = 1 shows the device, Bit0 = 1 for the control of busy (you can omit this step)
Send 44 to 0xf000,
Wait for busy = 0,
Send CC to 0xf001,
Wait for busy = 0,
Send BE to 0xf000,
Wait for busy = 0,
Blank reading time,
Wait for busy = 0,
Then read is DS18B20 internal data. Read one must wait for the busy = 0, otherwise the controller will reject all operations.
Search ROM:
Send F0 or EC to 0xf001,
Wait for busy = 0 shows the device is ready,
Read 0xf001 the existence of Bit1 = 1 shows the device, Bit0 = 1 for the control of busy (you can omi

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。

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.
