Here's the example used in the original code above.switch(ch) { case 'a' : command = 10; break; case 'r' : command = 20; break; case 'z' : command = 30; break; default : command = 0; } If the character ch is not 'a', or 'r', or 'z' then the variable command is ...
if语句后面可以跟随一个可选的else if ... else语句,其对于测试各种条件非常有用。 switch case 语句 类似于if语句,switch ... case通过允许程序员指定应在各种条件下执行的不同代码来控制程序的流程。 条件运算符 ? : 条件运算符? :是C语言中唯一的三元运算符。 7、循环 while循环 while循环将会连续、无限...

[MacCraiger] used the same sort of switch and aluminum case that you might see on a pedal board, as he figured they’d be better suited to a lifetime of being stepped on than something he 3D printed. Up on the desk, and this time in a printed case, is the Arduino Leonardo that ...
switch (Serial.read()) { case 'A': Serial.println("That's the first letter of the abecedarium."); break; case 'Z': Serial.println("That's the last letter of the abecedarium."); break; } } Side notes: By default, Unity uses a subset of the .NET framework, so if you get th...

This example shows how to enable callbacks to read streaming ASCII terminated data from an Arduino® board using the serialport interface. This example uses an Arduino Due; however, most Arduino boards should work. Upload a Program to the Arduino Plug in an Arduino board to your computer. ...
问如何根据esp32 arduino (步进电机控制器应用程序)的要求删除和重新启动hw定时器(用于中断)EN步进电机是一种将电脉冲转化为角位移的执行机构。当步进电机的驱动器接收到一个脉冲信号，它就驱动步进电机按设定的方向转动一个固定的角度（即步长）。通过控制脉冲个数来控制角位移量，达到准确定位的目的；通过控制脉冲...
