      在7寸屏调试GT911触摸时，触摸正常点击没什么问题，滑动触摸条就比较卡顿，触摸时中断频率在97，7寸屏应该是足够了，不知道什么原因，各位大佬指点迷津
      中断频率：

        可以尝试中断绑定其他CPU核心，例如CPU1

          @shuaige 在 GT911 触摸滑动不流畅 中说：

          滑动触摸条就比较卡顿

          可能是CPU处理速度问题，测试一下把双缓冲关了，丝滑了，也撕裂了。

            @whycan 晕哥，界面是qt做的，关闭双缓冲是在qt中处理吗

                  @awwwwa 仅允许 CPU 0 处理这个 IRQ
