Serial.print(“N”)输出为“N” Serial.print(“Hello world.”)输出为“Hello world.” 也可以自己定义输出为几进制(格式);可以是BIN(二进制,或以2为基数),OCT(八进制,或以8为基数),DEC(十进制,或以10为基数),HEX(十六进制,或以16为基数)。对于浮点型数字,可以指定输出的小数数位。例如 Serial.print(...

返回值byte 这个返回值通常是用不到的 示例#include <LiquidCrystal.h> LiquidCrystal lcd(12, 11, 10, 5, 4, 3, 2); void setup() { lcd.print("hello, world!"); } void loop() {} 返回主菜单
在Arduino编程语言中,Serial.print()是一种用于输出调试信息的函数。它可以将Arduino板上的数字或文本信息输出到串口,并通过串口线连接到计算机或其他设备上。它可以用于对代码进行调试和测试,以及将数据传输到其他设备。Serial.print()的基础用法 Serial.print()函数的基础语法非常简单。它需要一个参数,该参数是要...
写入二级制数据到串口。发送的数据以一个字节或者一系列的字节为单位。如果写入的数字为字符,需使用print()命令进行代替。 语法 Serial.write(val) Serial.write(str) Serial.write(buf, len) Arduino Mega还支持:Serial1,Serial2,Serial3 (替代Serial) 参数 val: 以单个字节形式发的值 str: 以一串字节的形式发...
I successfully started with the Arduino Framework and today I tried the ESP IDF, beginning with the "Hello World" example. Unfortunately I don't see the outputs generated by the program. The standard output in the Arduino Framework is the serial monitor ( using Serial.println(...) ). In...
