如何用I2C实现CY8C27 43-24PXI中的SHT10湿度传感器？

这是PSoC 5.2的问题，所以这不是一个好的组。管理员，你能改变我的职位吗？谢谢。



     以下为原文
  This is problem about PSoC 5.2 so this is not good group. Admin can you change my post location ? Thanks.

论坛是正确的，你正在谈论PSoC1和设计师5.2（我建议更新到5.3）。
当你给我们提供一个到传感器的数据表的链接时，它会帮助我们很多，所以我们可以考虑如何连接它。
鲍勃



     以下为原文
  The forum is the correct one, you are talking about PSoC1 and designer 5.2 (which I suggest to get updated to 5.3).
    It would help us a lot when you provide us with a link to the datasheet of your sensor, so we could consider how to get it connected.

看看这个地址：HTTP://www.
它们给出了与传感器接口的示例代码。
正如在其附注中所解释的，它是一个TWI接口，但它不是I2C兼容的，因为数据线在SCK高的时候移动。



     以下为原文
  Have a look to this address : http://www.sensirion.com/en/products/humidity-temperature/download-center/
    They give example code to interface with their sensor.
     
    As is explained in their Appnote, it is a twi interface but it's not I2C compliant since the data line move while SCK is high.

从数据表-
SHT1X的串行接口被优化用于传感器读出和有效功耗。传感器不能通过I2C协议解决；然而，传感器可以连接到I2C总线，而不干扰连接到总线的其他设备。控制器必须在协议之间切换。
看起来你必须创建自己的或端口协议。
问候，Dana。



     以下为原文
  From the datasheet -
     
    The serial interface of the SHT1x is optimized for  sensor
readout and effective power consumption. The sensor
cannot be addressed by I2C protocol; however, the sensor
can be connected to an I2C bus without interference with
other devices connected to the bus. The controller  must
switch between the protocols.
     
    Looks like you will have to create your own, or port, protocol.
     
    Regards, Dana.

所以我能用这个传感器读出湿度吗？我想把这个传感器集成到RF扩展卡（FTRF）上，并通过PC桥（FTCP）从PSoC设计器5.2上传程序。我必须使用I2C协议。你对这个话题有什么看法？
谢谢大家的帮助：



     以下为原文
  So Can I use this senor to read humidity ? I would like to connet this senor to RF Expansion Card (FTRF) and upload program from PSoC Designer 5.2 by means of PC Bridge (FTCP). I must use I2C protocol.  What is your opinion on this topic ?

     
    Thanks for all help :)

数据表到SHT10：
HTTP://www.



     以下为原文
  Datasheet to SHT10 :
     http://www.sensirion.com/fileadmin/user_upload/customers/sensirion/Dokumente/Humidity/Sensirion_Humidity_SHT1x_Datasheet_V5.pdf

该传感器的数据表专门说明该设备可以操作/共享I2C总线，但
不是一个I2C可寻址设备。
所以答案是你的端口/使用/写一个有点敲击协议的设备，除非我失踪了。
某物。
问候，Dana。



     以下为原文
  The datasheet for that sensor specifically states the device can operate on/share an I2C buss, but is
    not an I2C addressable device.
     
    So answer is you port/use/write a bit banging protocol for that device, unless I am missing
    something.
     
    Regards, Dana.

请参考这个线程在SHT1X -HTTP://wwwyCysP.com／？APP =论坛和RID＝51642
此外，CY3171工具包页有用于所有电路板的代码示例，您可能会对修改UB-I2C桥- HTTP://wwwyCysP.COM/的代码感兴趣？DOCID＝32060



     以下为原文
  Please refer to this thread on SHT1x - http://www.cypress.com/?app=forum&rID=51642
     
    Also the CY3271 kit page has code examples for all the boards, you might be interested in modifying the code for the USB-I2C Bridge - http://www.cypress.com/?docID=32060

我必须使用什么样的模块？
谢谢大家的帮助。



     以下为原文
  What kind of moduls I must use ?
     
    Thanks for all help.

正如Danaa所说，你需要使用一个敲击协议。对于这种协议，没有UM可用。
你是否检查了我在上一篇文章中提到的链接，其中一个文档包含了与传感器交谈所需的所有代码。你必须修改它来反映你自己的情况，但不应该很困难。
希望它有帮助



     以下为原文
   As Danaa said you will need to use a bit banging protocol. No UM is available for this kind of protocol.
     
    Did you check the link I posted in my previous post, one of the document contain all the code necessary to talk with the sensor. You will have to modify it to reflect your own situation, but it should not be very difficult.
     
    Hope it helps

是的，我看过这份文件，但我不知道该怎么做。



     以下为原文
  Yes , I've seen this document but I have no idea on how to do it

使用AppNeNT中提供的代码配置两个引脚，一个为SCK，另一个作为数据。将两个引脚配置为上拉。假设您重命名PIN SCK和数据。
下面是您需要更改的代码的一部分。其他部分必须使用相同的程序进行更改。
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
chssWrue字节（无符号字符值）
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
//在感知器上写入一个字节并检查确认
{
无符号char i，误差＝0；
对于（i＝0x80；i & gt；0；I/= 2）/ /移位位形式化请求
{if（i，and value）数据＝1；/ /掩蔽值i，写入到敏感器总线
否则数据＝0；
（nopp）；/ /观察设置时间
SCK＝1；/CLK为敏感器总线
αnoph（）；αnoph（）；//脉冲约5μs；
SCK＝0；
（nopp）；/ /观察保持时间
}
数据＝1；/释放数据线
（nopp）；/ /观察设置时间
SCK＝1；//CLKα9用于ACK
错误=数据；//检查ACK（数据将被SHT11拉下来）
SCK＝0；
返回错误；//错误＝1在没有确认的情况下
}
/ /结束样本代码
您将改变包含SCK＝1的行；通过SkkDATAAdADDR＝SCKIMAGE；
您将改变包含SCK＝0的行；通过SCKYDATAYADDR和= ~SCKYMASE；
对于数据引线的引用也必须这样做。
接下来需要改变的是，你需要一个宏来执行5NU。
您必须修改包含SCK或数据引用的每个函数。任何其他代码都应该编译而不需要修改。
使用这种技术的最后一件事是读取/修改/写入问题。
当做



     以下为原文
  Using the code provided in the AppNote configure two pins, one as SCK and the other as Data. Configure the two pins as pull-up. Let's suppose you rename the pin SCK and DATA.
    Here is one portion of code you will need to change. Other portions will have to be change using the same procedure.
     
    //---------------------------------------------------------------------------------- 
    char s_write_byte(unsigned char value) 
    //---------------------------------------------------------------------------------- 
    // writes a byte on the Sensibus and checks the acknowledge 
    { 
    unsigned char i,error=0; 
    for (i=0x80;i>0;i/=2) //shift bit formasking 
    { if (i & value) DATA=1; //masking valuewith i , write to SENSI-BUS 
    else DATA=0; 
    _nop_(); //observe setuptime 
    SCK=1; //clk for SENSI-BUS 
    _nop_();_nop_();_nop_(); //pulswith approx. 5 us 
    SCK=0; 
    _nop_(); //observe holdtime 
    } 
    DATA=1; //release DATA-line 
    _nop_(); //observe setuptime 
    SCK=1; //clk #9 for ack 
    error=DATA; //check ack (DATA will be pulled down by SHT11) 
    SCK=0; 
    return error; //error=1 in case of no acknowledge 
    } 
    // End of sample code
    You will change the lines containing SCK = 1; by SCK_Data_ADDR |= SCK_MASK;
    You will change the lines containing SCK = 0; by SCK_Data_ADDR &= ~SCK_MASK;
    The same has to be done for the line refering to the DATA pin.
    The next thing required is to change the _nop_(); with a macro you know takes 5us to execute.
    You will have to modify every function containing a reference to SCK or DATA. Any other code should compile without or minor modification.
    One last thing to take into consideration using this technique is the Read/modify/write issue.

我应该使用协议-BooTrDL2C？
谢谢大家的帮助。

  Your CY3271 CDROM disc contains several firmware projects that
    pass data thru wireless bridge to SCD, Take a look at that code to
    see how to format and xmit the data. Also make sure you config
    the node to address the format of the data beinmg sent to it. There
    is a specific firmware example on the CDROM that takes thermistor
    data, passes it over wireless bridge, and plots it. Noite the latest CDROM

    Use this ap note, page 13, for code naming of pins, although sounds like
