Question

我正在尝试在Raspberry Pi3上设置一个“非品牌”触摸屏，当我运行我的python / kivy程序时遇到一些麻烦，视觉上一切都很好，但每当我需要移动一个滑块时，推一个按钮或其他什么。输入的y轴是反转的，请注意，当我在我的Windows机器上运行它时，它工作正常 As you can see the input for the buttons are inverted on the y axis

我知道这存在并且我已经尝试过，但它没有解决问题（在我的情况下）。 https://stackoverflow.com/a/34344458/7522859

我已经尝试在（在我的情况下）（.kivy / config.ini）下的配置文件中修复它，正如您所看到的那样，它会读取invert_y选项但不会同时执行1和0作为其值

所以问题是如何在kivy配置文件中反转输入的Y轴。我也看了一下this我并没有真正理解它，也许我只是愚蠢。

很抱歉，如果这篇文章不好的话。它的第一篇文章和英语不是我的母语。

我终于开始工作了。

我更改了hidinput.py下的第417行：

/usr/local/lib/python2.7/dist-packages/kivy/input/providers/hidinput.py

信用：How do if invert touch input in Kivy

并设置配置：

~/.kivy/config.ini

下的

ADS7846 = hidinput,/dev/input/event2,invert_y=0

Config Kivy＆gt;反转y轴的输入
