LSM330DLC使用什么加速度计?

据我所知,LSM330DLC是一个“系统级封装”,它是一个单独的加速度计和陀螺仪芯片封装在一起。实际的模具零件数量是多少?


我问的原因是LSM330DLC很难解释寄存器中各个位的作用。这些位似乎与LIS3DH匹配,但实际的寄存器地址是不同的。


此外,LIS3DH具有块数据更新(BDU)功能,可安全读取多字节(10和12位)数据寄存器,LSM330DLC表示不启用此功能。如何在没有损坏读数的情况下安全读取多字节数据?


底线问题是LSM330DLC的其他支持文档是什么? LIS3DH和AN3308似乎很接近,但不是完全匹配。

以下为原文




It is my understanding that the LSM330DLC is a 'System-In-Package', that is it is a separate accelerometer and gyro die packaged together. What are the actual die part numbers?


The reason I ask is that the LSM330DLC is rather spares on explanation of what the various bits in the registers do. Bit wise the bits seem to match the LIS3DH, however the actual register addresses are different.


Also the LIS3DH has the Block Data Update (BDU) feature to safely read the multi-byte (10 and 12 bit) data registers, where the LSM330DLC says not to enable this. How can the mutil-byte data be safely read without corrupted readings?


The bottom line question is what other supporting documentation is there for the LSM330DLC? LIS3DH and AN3308 seem close, however are not an exact match.

鲍勃你好,
我不知道任何其他错误。
坦率地说,我不负责数据表,但我正在努力帮助你。我们只是人类,有时我们会犯错误。
你提到的两个位并不重要。无论如何,如果其他东西想要清楚,请告诉我。

Hello Bob,
I'm not aware about any other errors.
Frankly, I'm not responsible for the datasheets but I'm trying to help you. We are only humans and sometimes we make a mistakes.
The two bits which you mentioned are not crucial. Anyway if something else want be clear let me know.

我感谢你的帮助,没有人认为值得花时间回应。
我会确保当其他人设计硬件时他们付出更多的尽职调查来查看编写软件的可用性,而不仅仅是让我清理混乱并成为项目迟到的原因因为坏/缺少文件。

I do thank you for your help, no one else even thought it was worth their time to respond.
I'll make sure that when other people design the hardware that they pay more due diligence to looking at what is avalaible for writting the software, rather than just make me clean up the mess and be the fall guy for the project being late due to bad/missing documentation.
