使用LPS22HB压力传感器无法得到响应

嗨，
 您正在使用的设置似乎是正确的。
 我能够使用相同的设置正确阅读，因此下面必定有一些奇怪的东西。
 我需要进一步的细节才能理解这种行为。
 你能给我发送带有WhoAMI_register（0x0F）读数的SPI时序图和压力数据读数（0x28h，0x29h和0x2A）吗？
 
 问候

Hi,
the setting you are using seems to be correct.
I am able to read properly using the same setting therefore there must be something strange underneath.
I need further details in order to understand this behaviour.
Can you send me the SPI timing diagram with the WhoAMI_register (0x0F) reading and the reading for pressure data (0x28h, 0x29h and 0x2A)?

我在这里也看到了类似的问题，使用I2C。
 
 
这时，我的两个寄存器设置为：
 
控制寄存器1：0x20
控制寄存器2：0x00
 
在这种情况下，我将进行10 Hz操作，连续（BDU）更新，并且没有低通数据配置。
 
对于控制寄存器2，我使用I2C然后从0x28,0x29和0x2A读取单字节压力，并且不希望设备自动递增地址，因此禁用。我也禁用了FIFO。
 
我希望我能够直接从0x28,0x29和0x2A读取数据并以高达10 Hz的速率转换为压力。
 
此时，我只能从这些寄存器上的器件读取[0x00,0x00,0x2D]。这显然是不正确的。
 
我能够读取和写入设备上的所有其他寄存器，包括WHO_AM_I寄存器，并且返回正确，以及配置寄存器的设置/读取。
 
关于这里可能发生的事情的任何想法？

I have seen similar issues here as well using I2C.


At this time, my two registers are set as:

Control Register 1: 0x20
Control Register 2: 0x00

I'm going for 10 Hz operation in this case, continuous (BDU) updates, and no low pass data configurations.

For control register 2, I'm using I2C then single byte reads from 0x28, 0x29, and 0x2A for the pressure and don't want the device to automatically increment the address and so that is disabled.  I also have the FIFO disabled.

It is my expectation that I should then be able to read the data directly out of 0x28, 0x29, and 0x2A and convert to pressure, at a rate of up to 10 Hz.

At this time, I'm only able to read [0x00, 0x00, 0x2D] from the device on those registers. That is clearly not correct.  

I am able to read and write all other registers on the device, including the WHO_AM_I register and that comes back correct, as well as the setting/reading of the configuration registers.

Any thoughts on what may be happening here?

压力寄存器的读取与状态寄存器同步？
 如果不使用中断模式，则在读取输出寄存器之前，必须检查状态寄存器（27h）上的P_DA位（可用压力数据）。
 您必须轮询此位，当它设置为1表示生成新的压力数据，因此您可以在输出寄存器（0x28,0x29和0x2A）上读取此值。
 温度输出也是如此。

The reading of the pressure registers is sinchronized with the status register?
If you are not using the interrupt mode, before to read the output registers you have to check the P_DA bit (Pressure data available ) on status register (27h).
You have to poll this bit and when it is set  to 1 means that a new pressure data is generated and so you can read this value on output registers (0x28, 0x29 and 0x2A).
The same is for temperature outputs.
