        我记得以前是正常的

        三块新屏都是一样的问题，用万用表量了一下，触摸的时候屏的INT引脚确实不能下拉．

          刚刚有朋友提醒我，把中断腿设置为io模式，看能拉高拉低，

          测试 PE12 输出高低电平：

          echo $((4*32+12))
echo 140 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio140/direction
echo 0 > /sys/class/gpio/gpio140/value

          然后果然不能拉高拉低，难道板子坏了吗？

            还好板子多，换块板子再试一试，可以拉高拉低了．

            接着测试一下中断．
