Question

这里的第一次海报，请放轻松一下吧？：）

我目前正在使用Teensy 3.1 Arduino兼容主板，只是为了看看我能做些什么。所以我目前有一些代码，我发现它基本上只是模拟键盘并输入0000 ENTER，0001 ENTER，一直到9999.

我想调整代码，以便我可以将范围更改为我喜欢的范围，例如从2000-3000或2500-2600等开始。如果有人可以告诉我需要调整哪些行来实现，我会非常感激。

Answer 1

int counter = 0;是开始，if (counter <= 9999) {定义结束。根据您选择的开头更改0，为您选择的结尾更改9999。

代码有效，因为keyboard.press和keyboard.release接受一个字符来选择要按下和释放的键。它使用sprintf将counter的值获取到char数组pin，使用变量fakecounter的值作为中间人，从int转换为string。计数器的值增加，并且在输入键的同时在虚拟键盘中键入。

将输入更改为较小的范围
