hi,最近我在使用S3 idf的touchpad功能,使用导线或者是焊盘测试的话,效果都非常好,但是如果使用铜线引出至铜片,然后使用2.89mm厚的亚克力板压在铜片上的话,那么就无法识别,我已经将threshold调至10% ,仍然无法识别。 各位大佬可否给些建议,是因为亚克力板的问题吗?还是程序有可以修改的地方呢?因为产品设计的触摸部分...

编写回调函数,注意这里的函数名不能变,因为这是lvgl的回调函数,程序大概意思是lvgl会定时执行 my_touchpad_read ,如果有触摸按下,则会执行if语句,并将新的触摸坐标赋值给lvgl voidmy_touchpad_read(lv_indev_drv_t*indev_driver,lv_indev_data_t*data){/* 替换成你的 */if(touch_touched()) { ...
