利用状态机编程学习触摸屏
PRESSED状态就是低电平的状态。会在这三种状态之间转换，同时对外输出最终的结果。 如果在PRESSED状态再来检测可以检测触摸是否是一直被按下，这时候可以判断长按或短按。 如果在PRESSED状态下检测到PENIRQ变成高电平，就转入RELEASE状态，同时对外输出这个触摸没有被按下。 在消抖以后检测到PENIRQ是低电平或在PRESSED状态检测到PENIRQ是低电平，对外输出TOUCH_PRESSED。 { touch_state = XPT2046_STATE_PRESSED; //切换到触摸屏被按下的状态 result = TOUCH_PRESSED; //输出触摸屏被按下 } _STATE_PRESSED; //一直处于被按下状态，在这里可以检测是否长按 result = TOUCH_PRESSED; //输出触摸屏被按下 } else { touch_state

1.5K10编辑于 2022-09-05 代码可读性与命名艺术：空间布局与命名的核心原则
例如，这里有一个处理一些用户输入的代码块：x_pressed = false;y_pressed = false;if (input == "x") { print "You pressed x! ; x_pressed = true;}else if (input == "y") { if (not y_pressed) { print "You pressed y for ; y_pressed = true; if (x_pressed) { print "You pressed x and then y!" 然而，如果这在很多其他代码中，我们可以这样使它更可读：x_pressed = false;y_pressed = false;if (input == "x") { handle_x(x_pressed );}else if (input == "y") { handle_y(x_pressed, y_pressed);}我们可以通过减少到这个来使它更可读：handle_input(input);
