      最近再调试f1c200s的板子,运行LVGL,触摸屏触摸的时候,基本整个屏幕都不能触摸,唯独最左边的一点点地方是可以触摸的,而且位置也不对,驱动是有的,就是触摸的时候出现触摸不了。不知道是不是没校准屏幕,屏幕是480*272的4.3寸RGB。驱动芯片是ns2009。求解!!!

            @whycan 用tslib-触摸屏校准的./ts_test是可以点击的,会不会是我的LVGL没弄好?

              电阻屏得用 ts_uinput 转换过的设备。

                  你现在是不是直接用驱动生成的 /dev/input/eventX ?

                          不是不能用,是这个数据不是真实坐标数据,只是一个adc值而已,而app需要的不是这种数据。

                          app需要的是用tslib进行各种滤波去抖和坐标计算后的数据。

                              我已经三次提到 ts_uinput 了,您怎么不试一试呢?

                              这个解决方案是最简单的了。
