您好，几个月前我在SPI和I2C模式下使用过LPS331AP进行首次测试。
 
由于LPS331AP限制，我等待新的LPS25H evb STEVAL-MKI142V1。
我尝试读取WHO_I_AM寄存器，但我没有回复期望值0xBD，我在I2C中读取= 0xFF，在SPI中读取0x00。
 
LP331AP的源代码是一样的，LPS25H有什么问题？
 
亲爱的郑，你能解决你的问题吗？
 
谢谢。

Hello, I have used LPS331AP in SPI and I2C mode for first test some months ago.

Due to LPS331AP limitation I wait the new LPS25H evb STEVAL-MKI142V1.
I try to read WHO_I_AM register but I do not reply the expected value 0xBD, I read =0xFF in I2C and 0x00 in SPI.

Source code are the same for LP331AP, what's wrong with LPS25H?

Dear Cheng, have you solve your problem very similar to my?

Thank you.

亲爱的，我的问题解决了。这是STEVAL-MK142V1，LPS25H损坏。
 
这意味着如果SDA SCL驱动程序损坏，它将回复来自WHO_I_AM寄存器的虚拟值。
现在第二个STEVAL它适用于I2C总线。
 
问候

Dear All, my problem is solved. It was STEVAL-MK142V1 with LPS25H damage.

This mean that if the SDA SCL driver is damage it reply with dummy value from WHO_I_AM register..
Now second STEVAL it works on I2C bus.

Maurizio

你能附上一些看过WhoAmI的示例代码吗 - 我一直试图这样做，但我还没有成功。 （使用STM32F4 Discovery Board和LPS25H）

Can you attach some example code that reads WhoAmI - I have been trying to do this, and I have not been successful. (Using STM32F4 Discovery Board and LPS25H)
