问题描述

我在BBB上安装了Adafruit_BBIO模块(我从github下载并手动安装)。
GPIO正常工作,但是当我尝试使用ADC时,出现如下错误:

I installed the Adafruit_BBIO module on my BBB (I downloaded it from github and installed manually).The GPIO works just fine but when I try to use the ADC I get an error as follows:

import Adafruit_BBIO.ADC as ADC
ADC.setup()

错误:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
RuntimeError: Unable to setup ADC system. Possible causes are:
- A cape with a conflicting pin mapping is loaded
- A device tree object is loaded that uses the same name for a fragment: helper

我找不到这个问题的答案。
我应该只使用旧版本的ubuntu吗?

I couldn't find an answer for this problem.Should I just use an older version of ubuntu?

谢谢!
