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
