HTS211具有不同的IIC地址

嗨，
与HTS221湿度传感器相关的8位从机地址（SAD）是唯一的，不能更改或编程。
 
 但是，可以采用其他方式在I2C总线上连接更多HTS221器件。
 1.将所有器件的SDA引脚连接到I2C SDA线，并复用SCL线。
 2.将I / O扩展设备用于I2C总线。另一个选项涉及SPI总线接口的使用。
 
 CS是串行端口使能。它由SPI主控制器控制，允许及时选择一个器件。 CS在传输开始时变为低电平，并在结束时返回高电平。
 
 
 问候
 安东内拉嗨，
 
 我们需要一个用于物联网家庭应用系统的湿度传感器。 HTS211看起来非常好看，因为它似乎在任何时候都是I2C可读的（而其他传感器通常需要一个复杂的Measure-Pause-Read Intervall时序）。
 
 我们肯定需要将多个传感器连接到一条I2C线路（我们使用长距离I2C） - e。 G。一个传感器用于内部/室内温度/湿度，并且需要安装一个或两个其他传感器（最终客户自己可以根据需要连接它们），例如： G。对于某些外部温度测量点....
 
 为此，我们必须让HTS211具有不同的I2C地址。可以通过引脚固定编程（例如，不同的订货号HTS211-A1，HTS211-A2）或以某种形式编程 - 或者如果您100％确定您的Flash解决方案，它也可以是可编程的。 （但我们更喜欢一些修复解决方案 - 在Flash中编程IIC-Adress听起来有点危险）。
 
 PS：这部分什么时候可以在分销商处买到？

Hi,
The 8-bit slave address (SAD) associated to the HTS221 humidity sensor is unique and this last cannot be changed nor programmed.

However it is possible to adopt other ways to connect more HTS221 devices on I2C bus.
1. Connect the SDA pin of all devices to the I2C SDA line and to multiplex SCL line.
2. Use an I/O expansion device for I2C bus.An other option concerns the use of SPI bus inferface.

CS is the serial port enable. It is controlled by the SPI master and allows to select the one device at time. CS goes low at the start of the transmission and goes back high at the end.

Antonella Hi,

we need a humidity sensor for IoT home application systems. HTS211 looks very nice as it seems to be I2C readable at any time (whereas other sensors often need a complicated Measure-Pause-Read Intervall timing).

Just we definitely would need the possibility to connect several sensors to one I2C line (we use long distance I2C) - e. g. one sensor for internal / room temperature/humidity, and one or two other sensors need to be mounted optionally (the end customer himself can just connects them if he wants), e. g. for some outside temperature measurement point ... .

For this is it necessary for us to get the HTS211 with different I2C adresses. Either fix programmed (e. g. different order numbers HTS211-A1, HTS211-A2), or in some form programmable - by pin, or if you are 100% sure about your Flash solution, it could also be programmable. (but we would prefer some fix solution - programming IIC-Adress in Flash sounds a bit dangerous).

PS: When will this part be available at distributors?

我们的模块只有一个4针I2C连接器 - 为此我们连接了更多种类的本地传感器模块（也包括振动传感器......）。
 
 
 当然理论上还有其他布线可能性......但这不是很实用，请理解。因此，你的建议真的不是很有帮助 - 它听起来有点像个笑话。
 
 我们需要至少1-2个I2C地址可能性，否则我们必须使用另一个供应商的湿度传感器，他们允许改变I2C地址。 （因为您的HTS211没有用于地址配置的备用引脚，我不希望您添加这样的“地址引脚”功能 - 这将是一个完整的芯片设计更改...但可能您可以提供HTS211 2进一步的I2C地址 - 这真的非常好！）。



以下为原文





Our modules have only a 4 pin I2C connector - to this we connect a wider variety of local sensor modules (also vibration sensors...).


Of course theoretically there are other wiring possibilities ... but this is a not very practical, please understand. Therefore your proposal really is not very helpful - it more sounds a bit like a joke.

We need at least 1-2 further I2C adress possibilities, otherwise we have to use humidity sensors of another supplier, who allows variation of I2C address. (as your HTS211 has no spare pin for address configuration available, I do not expect that you add such an ''address pin'' functionality - this would be a complete chip design change... but possibly you could offer the HTS211 with 2 further I2C addresses - this would be really very nice!).

感谢您的反馈。
 我们将考虑您对将来开发设备新功能的建议。
 
 问候
