Arduino EEPROM Example Number1:In example 1 we will write a simple program which displays the data stored in the EEPROM, delete/erase the stored string message, and asks again for the new message to enter. You can enter the text using the Arduino’s serial monitor. For the best ...
mySerial.write(Serial.read()); } } [Get Code] 更多 The Software Serial Library TwoPortReceive – 当接收到一个特殊字符时,两个串口端口由一个切换到另一个的数据来接受数据。. MultiSerialMega - 使用在Arduino和Genuino Mega上的两个有效串行端口。 Serial Call Response - 通过呼叫-响应(握手)方法来...
This example code is in the public domain. */ void setup() { // initialize both serial ports: Serial.begin(9600); Serial1.begin(9600); } void loop() { // read from port 1, send to port 0: if (Serial1.available()) { int inByte = Serial1.read(); Serial.write(inByte); } ...
Serial.begin(speed)// 初始化串口的波特率，常用 9600、19200、57600、115200。// 波特率，每秒传输的 bit 数 Serial.available( )// 不带参数 // 返回串口缓冲区当前剩余字符的个数，用以判断串口缓冲区有无数据。// 当 serial.available()>0 时，判断串口收到了数据，可以读取 Serial.read( )// 读取串口...
Serial.write(myFile.read()); } myFile.close(); } else { Serial.println("error opening test.txt"); } } void loop() { // empty } 复制代码 代码描述:首先我们需要包括标准的SD和SPI库,创建一个“File”对象并定义SPI总线的ChipSelect片选引脚,本例中为Arduino Mega开发板的引脚53。对于本示例,我...

硬件串口通信(UART)——HardwareSerial 类库 除了常见的函数外,另外比较常用的 peek() 功能:返回1字节的数据,但不会从接受缓冲区删除数据,与read()函数不同,read()函数读取该函数后,会从接受缓冲区删除该数据。 write() 功能:输出数据到串口。以字节形式输出到串口,它与print()的区别在于:当使用print()发送一...
In this Arduino Serial example, we will write text to the Arduino serial port, which will send it over the USB cable to your computer, which will then display that text in a terminal window. In the ‘setup()’ function mentioned above, add the following lines to start the Arduino serial...
