电容触摸(Capacitive touch) 在machine模块中使用TouchPad类: from machine import TouchPad, Pin t = TouchPad(Pin(14)) t.read() # 触摸时返回较小的数字 1. 2. 3. 4. TouchPad.read返回一个与电容变化相关的值。当引脚被触摸时,通常是小数(通常为几十),而当没有触摸时,则是大数(超过一千)。不过,数值...

触摸屏驱动主要是修改触摸屏的事件回调函数:touchpad_read(),该函数在驱动设备注册部分被设定为回调函数。下面给出了例程中涉及触摸驱动的代码。 #include <CST816S.h> static void ta_event_cb(lv_event_t * e) //软键盘例程的触摸事件回调函数
(disp); } void my_touchpad_read(lv_indev_drv_t *indev_driver, lv_indev_data_t *data) { if (touch.available()) { data->state = LV_INDEV_STATE_PR; /*Set the coordinates*/ data->point.x = touch.data.x; data->point.y = touch.data.y; Serial.print("Data x "); Serial....
