I2cdevice：我如何从特定的reg地址读取 [英] I2cdevice: how do I read from a specific reg address

问题描述

我有一个MPU6050，我正在尝试为它写一个库。

https://store.invensense.com/datasheets/invensense/MPU-6050_DataSheet_V3%204.pdf [<一个href =https://store.invensense.com/datasheets/invensense/MPU-6050_DataSheet_V3%204.pdftarget =_ blanktitle =New Window> ^ ]



它从传感器读取数据并将值存储在特定的寄存器地址中。我希望能够从特定的寄存器中读取，但我在UWP I2C设备或提供商中找不到任何关于如何执行此操作的信息。



有没有人有任何想法？



谢谢



（PS：我宁愿用c ++也这样做）



我尝试了什么：

Hi,

I have an MPU6050 that I'm trying to write a library for.
https://store.invensense.com/datasheets/invensense/MPU-6050_DataSheet_V3%204.pdf[^]

It reads data from it's sensors and stores the values in specific register addresses. I want to be able to read from a specific register but I can't find anything on how to do this in the UWP I2Cdevice or the providers.

Has anyone got any ideas?

Thanks

(PS: I'd rather do it in c++, too)

What I have tried:

device.Read(byteArrayThatReadsEverythingInOneHit);

但这很慢所以我必须经常重读〜：S

But this is slow so I have to re-read often ~:S

推荐答案

Quote：

然后主设备将registeraddress（RA）放在总线上。在MPU-60X0确认接收到寄存器地址后，主机将寄存器数据放入总线

Then the master puts the registeraddress (RA) on the bus. After the MPU-60X0 acknowledges the reception of the register address, the master puts the registerdata onto the bus
