[Ethernet]
説明
Write data to all the clients connected to a server. This data is sent as a byte or series of bytes.
Syntax
// telnet defaults to port EthernetServer server = EthernetServer(int); server.write(val) server.write(buf, len)
Parameters
val
: a value to send as a single byte (byte or char)buf
: an array to send as a series of bytes (byte or char)len
: the length of the buffer
Returns
byte (write()
returns the number of bytes written. It is not necessary to read this.)
Example
#include <Ethernet.h> // network configuration. gateway and subnet are optional. byte mac[] = { 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 }; //the IP address: byte ip[] = { 10, 0, 0, 177 }; // the router's gateway address: byte gateway[] = { 10, 0, 0, 1 }; // the subnet: byte subnet[] = { 255, 255, 0, 0 }; // telnet defaults to port 23 EthernetServer server = EthernetServer(23); void setup() { // initialize the ethernet device Ethernet.begin(mac, ip, gateway, subnet); // start listening for clients server.begin(); } void loop() { // if an incoming client connects, there will be bytes available to read: EthernetClient client = server.available(); if (client == true) { // read bytes from the incoming client and write them back // to any clients connected to the server: server.write(client.read()); } }
