4.15. Setting Up Processing on Your Computer to Send and Receive Serial Data Problem You want to use the Processing development environment to send and receive serial data. Solution You can get the Processing application from the Downloads section of the Processing website, http://processing.org...
SofaWareSerial() 功能:这是SoftwareSerial类的构造函数,通过它可以指定软串口的RX和TX引脚 语法:SoftwareSerial mySerial = SoftwareSerial(rxPin, txPin) listen() 功能:开启软串口监听状态 arduino在同一时间仅能监听一个软串口,当需要监听某一串口时,需要对该对象调用此函数开启监听功能 overflow() 功能:检测缓冲...
An Arduino Library that facilitates packet-based serial communication using COBS or SLIP encoding. Features PacketSerial is an small, efficient, library that allows Arduinos to send and receive serial data packets (with COBS, SLIP or a user-defined encoding) that include bytes of any value (0 ...
Serial.available() 参数 None 返回 串口已经准备好的字节数 例子 int incomingByte = 0; // for incoming serial data void setup() { Serial.begin(9600); // opens serial port, sets data rate to 9600 bps } void loop() { // send data only when you receive data: ...
The goal of this code is simple: to receive AT commands from the Arduino’s serial window to send them to the ESP8266, and to print the ESP8266’s response to the command or to other actions (such as receiving an HTTP request). ...
// An EthernetUDP instance to let us send and receive packets over UDP EthernetUDP Udp; void setup() { // start the Ethernet and UDP: Ethernet.begin(mac, ip); Udp.begin(localPort); Serial.begin(9600); } void loop() { // if there's data available, read a packet ...

SPI,是英语Serial Peripheral interface的缩写,顾名思义就是串行外围设备接口。是Motorola首先在其MC68HCXX系列处理器上定义的。SPI接口主要应用在 EEPROM,FLASH,实时时钟,AD转换器,还有数字信号处理器和数字信号解码器之间。SPI,是一种高速的,全双工,同步的通信总线,并且在芯片的管脚上只占用四根线,节约了芯片的管...
