如何在raspberry pi 3上访问ID_SD和ID_SC引脚作为GPIO [英] how to access ID_SD and ID_SC pins as GPIO on raspberry pi 3

问题描述

我正在使用智能扩展板，它具有从扩展板到pi的标准带状电缆。某些设备是"硬连线"的。通过带状电缆使用pi上的设置端口。

I am working with a smart expansion board which has a standard ribbon cable from the expansion board to the pi . Certain devices are "hard wired" to work with set ports on the pi via the ribbon cable.

我现在将超声波传感器连接到扩展板，该扩展板要使用引脚27和引脚28 ID_SD和ID_SC进行通信。我已经安装了微软闪电提供商但仍然没有让我将这些引脚用作标准gpio。 

I now have ultra sonic sensor connected to the expansion board which wants to use pin 27 and pin 28 ID_SD and ID_SC for communication. I have installed the microsoft lightning provider but still it is not letting me use these pins as standard gpio. 

关于如何作为标准gpio引脚访问这些引脚的任何想法？我在python中有示例代码使用这些引脚作为GPIO在raspbian上运行但似乎我无法将其直接移植到windows iot。

Any ideas on how I can access these pins as standard gpio pins ? I have sample code in python using these pins as GPIO which runs on raspbian but it seems I can't port this directly to windows iot.

任何帮助将不胜感激！

Hello Chris Gilliam，

Hello Chris Gilliam,

你的意思是针脚27和ping 28在扩展板上还是在PI上？

Did you mean the pin 27 and ping 28 is on the expansion board or on the PI?

来自&absp; Raspberry Pi 2& 3引脚映射，表明引脚27和ping 28保留供将来使用，此时这两个
引脚不能使用。所以你可以尝试使用其他有效的引脚。

From the Raspberry Pi 2 & 3 Pin Mappings, it shows that the pin 27 and ping 28 are reserved for future use, at this moment these two pin can not be used. So you can try to use other valid pins instead.

最好的问候，

Michael
