LPS22HB单发模式读取状态和压力数据没有变化

嗨，
我还不清楚你是否已经应用了单次触发模式的程序，在Config Reg（43h）中设置了CTE位，如应用笔记AN4672所述。
如果没有，请尝试执行以下步骤：
在寄存器43h中写入0x20h
2-写CTRL_REG2（设置一个镜头位以开始新的转换）
3-轮询STATUS_REG（27h）中的状态位，当数据准备就绪时，读取压力输出寄存器。
4-（可选）读取CTRL_REG2以检查单击位是否已复位（自清除）。
 
 
问候

Hi,
I have not clear if you have applied the procedure for one shot mode, set CTE bit in Config Reg (43h), described in application Note AN4672.
If not, please try to do the following steps:
1-Write 0x20h in reg 43h  
2- Write CTRL_REG2 (set one shot bit to start a new conversion)
3- Polling the status bit in the STATUS_REG (27h) and when tha data is ready, read the pressure output registers.
4- Optionally, read the CTRL_REG2  in order to check that the one shot bit has been reset (it is self clear).

嗨，Antonella，
 
 谢谢你的答案。
 
 在PowerOn上
 reg43h = 20H
 reg10h = 0
 reg11h = 10H
 reg27h = 02h（准备好温度数据）
 如果我读到温度：
 reg2Bh：2Ch = 0000h，
 现在reg27h = 0
 
 我试着
 写reg43h = 20h
 写reg11h = 11h
 然后轮询reg27h - 它等于0
 读reg11h = 11h
 
 我也试着
 写reg43h = 0
 写reg43h = 20h
 写reg11h = 11h
 然后轮询reg27h - 它等于0
 轮询reg11h - 它等于11h
 
 所有这些我都会在几秒钟内发送和读取，使用监视器应用程序，我手动编写regs的nums及其状态。
 
 可能是，reg43h中的CTE位不是第5位（bbCTEb bbbb）？
 AN4672在reg43h中没有对该位的位置进行校正，我找不到reg43h位的描述。州reg43h = 20h我只能通过阅读reg43h获得。
 在数据表中没有提到这个reg。
 
 最好的祝福，
 瓦迪姆
 
 附：
 我试着写信给reg43h＆lt; 1,2,4,8,10h，20h，40h，80h，然后写入reg11h＆lt; 11h。反应没有变化。
 我还写了移位寄存器RPDS_L：RPDS _H然后读取reg28：29：2A - 它们的状态被转换为输入到RPDS值。
 因此，LPS22HB对SPI事务做出反应，但不能完成测量。

Hi, Antonella,

thank You for answer.

on PowerOn
reg43h=20h  
reg10h=0
reg11h=10h
reg27h=02h  (temperature data ready)
if I read the temperature:
   reg2Bh : 2Ch = 0000h,
   and now reg27h=0

I try to
write reg43h=20h
write reg11h=11h
then polling reg27h - it equals 0
read reg11h=11h

I also try to
write reg43h=0
write reg43h=20h
write reg11h=11h
then polling reg27h - it equals 0
polling reg11h - it equals 11h

All this I send and read with intervals in a few seconds, using monitor application, where I manually write the regs' nums and their states.

May be, CTE bit in reg43h is not the 5th one (bbCTEb bbbb) ?  
AN4672 doesn't concider the position of this bit in reg43h, and I can't find the reg43h bits' description. The state reg43h=20h I get only by reading reg43h.  
And in Datasheet this reg isn't mentioned.

Best regards,
Vadim

P.S.
I tried to write to reg43h < 1,2,4,8,10h,20h,40h,80h, then write to reg11h<11h. No changes in reaction.  
Also I wrote to shift regs RPDS_L : RPDS _H then read reg28:29:2A - their states are shifted for entered to RPDS value.
So, LPS22HB reacts for SPI transactions, but doesn't accomplish measurement.

嗨Vadim，
 
就像你一样，我不懂CTE，因为它没有在LPS22HB数据表中描述。你现在明白了么？你解决了问题吗？
 
 
我使用了一次拍摄模式，我不需要设置CTE位但它有效！

Hi Vadim,

just like you, I don't understand the bit CTE because it is not described in LPS22HB datasheet. Do you understand now? Have you solved your problem?


I have used one shot mode, and I didn't need to set CTE bit but it worked!!
