The sketch below is based onLimor Fried's version of debounce, but the logic is inverted from her example. In her example, the switch returns LOW when closed, and HIGH when open. Here, the switch returns HIGH when pressed and LOW when not pressed. 下面的代码基于 Limor Fried 版本的去抖,...
2.跑lvgl库自身提供的示例代码 lvgl自身提供了很多的example,比arduino GFX库的LVGL的示例程序要丰富得多,所以我们需要把lvgl自身提供的示例程序跑起来,这样才更有利于学习lvgl。 上图是一个表盘的示例程序。 百度查找到类似解决方法 答案就是把相关的文件或文件夹复制到lvgl/src路径下,然后再去编译。 这是一个编译...

原因是TIMER0 (用于Arduino延迟的默认计时器)占用了脉宽调制控制。延迟函数的测试代码如下:unsigned long int sec; sec = ((16000000秒延迟。它正常工作,但在那之前,我用过的其他设置不起作用。这些变化是: 浏览7提问于2018-09-05得票数 0 回答已采纳...

This requires an output with PWM using a unused timer. Currently only RAMPS 1.0 doesn’t have a free timer for PID control. PID control is only implemented for extruder. For a better overview, lets have a look at the parameter used:...
