无法从 eGalax 设备获取触摸输入到 QtQuick 应用程序
Can't get touch input from eGalax device to QtQuick application
我正在尝试将 触摸输入 从 eGalax resistive touch device 转换为 eglfs window 运行ning 示例 QtQuick2 代码。我失败了好几天。触摸屏通过 USB 连接到 Raspberry Pi B 并且适用于 raspbian jessie 桌面。但是如果我 运行 示例 QtQuick2 代码应用程序不会获得任何触摸输入。但是，对于示例代码，使用鼠标效果很好。
我已经尝试使用 tsLib，但 ts_test x 和 y 坐标始终显示为 0。
我也尝试使用“./samplecode -plugin evdevtouch:/dev/input/event1”但没有成功。如果触摸屏幕，则打印输出 "Unhandled MSC event code MSC_SCAN (0x4)"。因此，应用程序或鼠标光标没有响应。

也许有人对我有线索。感谢您的帮助。
当与相对较新的内核一起使用时，tslib 中存在一个特定于您的触摸屏设备的错误。如果您使用最新的 1.15-rc2 版本，很快就会是 1.15，并且 module_raw input 在您的 ts.conf 中，应该可以正常工作。
