Raspberry Pi 3上i2c通信突然失败。 [英] Sudden failure of i2c communication on Raspberry Pi 3.

问题描述

我有一个设置，其中一个小小的3.2正在通过i2c与RPi 3 B +交谈。几个月以来，一切都运行良好，直到上周，通信开始失败，给我错误：

I have a setup where a teensy 3.2 is talking to a RPi 3 B+ over i2c. Everything was working great for months up until this past week where the communications started to fail giving me the error:

抛出异常：BrightBeats.exe中的'System.Runtime.InteropServices.COMException' br />
WinRT信息：与设备通信时发生意外错误。

Exception thrown: 'System.Runtime.InteropServices.COMException' in BrightBeats.exe
WinRT information: An unexpected error occurred when communicating with the device.

实际的引脚设置很好，因为它以前工作正常。没有任何代码被更改导致双方的错误，所以我很难找到问题。我在6月份的一个论坛上看到，一个Insider Preview更新导致i2c不能再工作了，
所以我用版本10.0.14393.0重新调整了Pi，但仍然没有运气。

The actual pin setup is fine as it was previously working. No code had been changed leading up to the error on both sides so I'm struggling to find the issue. I read on a forum here back in June that an Insider Preview update caused i2c to not work anymore, so I reflashed the Pi with build 10.0.14393.0, still no luck.

在此错误发生之前，我收到时钟延长超时错误，询问时钟引脚是否被从器件保持为低电平。但现在它不再警告这一点。

Right before this error, I was receiving a clock stretching timeout error asking if the clock pin was being held low by a slave device. But now it doesn't warn of this anymore.

任何帮助都将不胜感激，

Any help would be appreciated,
