Serial.println(1.23456, 0) gives "1" Serial.println(1.23456, 2) gives "1.23" Serial.println(1.23456, 4) gives "1.2346" 语法(Syntax): Serial.print(val) Serial.print(val, format) val:需要输出的值,支持任何类型数据 format:指定数据格式 返回值(Returns): 返回print() 函数输出的字符数据个数,长...
Serial.print(x,DEX); //以十进制格式将 x 打印输出 Serial.print("\t"); //横向跳格 Serial.print(x,HEX); //以十六进制格式将 x 打印输出 Serial.print("\t"); //横向跳格 Serial.print(x,OCT); //以八进制格式将 x 打印输出 Serial.print("\t"); //横向跳格 Serial.print(x,BIN); /...
Serial.print(数据)默认为十进制等于Serial.print(数据,DEC)。 Serial.print(data, encoding) 经序列埠传送资料,提供编码方式的选项。Serial.print(数据,数据的进制)如果没有指定,预设以一般文字传送。 范例: Serial.print(75); // 列印出 "75" Serial.print(75, DEC); //列印出 "75" Serial.print(75, H...
The Arduino platform has blossomed into a large ecosystem of developers and products capable of using the same or similar syntax. Learning the Arduino syntax will enable you to use a broad variety of development kits on the market today. This tutorial covers the very first steps required to pro...

这里有一个转义引用的例子:>>>print('This won't work') File "<stdin>", line 1 print('this won't work') ^ SyntaxError: invalid syntax >>>print('This won\'t error') This won't error 您可以通过使整个字符串成为原始字符串来实现这一点。在下一个例子中,'/n'用于移动到新的一行。
语法长度。 Syntax语法 x += y; // equivalentto the expression x = x + y; / 等价于x =x + y; x -= y; // equivalent to the expression x = x - y; // 等价于x =x - y; x *= y; // equivalent to the expression x = x * y; // 等价于x =x * y; x /= y;...
Syntax result = value1 + value2; result = value1 - value2; result = value1 * value2; result = value1 / value2; Parameters: value1: 任何常量或者变量,value2: 任何常量或者变量 编程小提示 整型常量的默认值是 int 类型,所以一些整型常量(定义中)的计算会导致溢出.(比如: 60 * 1000 会得 ...

Serial.write() 可以把一个数组的字节全部打印出来,但是需要指明长度。当然, 这里的 4 可以用 sizeof() 来求得。 但是由于这里是固定的 4 Byte,所以还是让单片机少点工作吧。 SyntaxSerial.write(val)Serial.write(str)Serial.write(buf, len)ParametersSerial: serial port object. See the list of available...
