FireBeetle 2 ESP32 C6-WOL网络唤醒电脑
本帖最后由 派大星ym 于 2024-4-14 21:47 编辑最近参加了DF发布的ESP32C6的试用活动，很幸运获得了试用资格，
收到板子后，用卡尺测量尺寸画了个模型。

WOL网络唤醒
当你出门在外需要远程开机电脑，你会采用什么方法来实现需求啦。拆开机箱安装开机卡；购买智能插座设置电脑为来电启动。可我并不想对电脑硬件有任何的改动以及不想额外花销去购买智能插座，目前似乎能满足我需求的就是WOL网络唤醒技术。
网络唤醒（Wake-on-LAN，WOL）是一种计算机局域网唤醒技术，使局域网内处于关机或休眠状态的计算机，将状态转换成引导（Boot Loader）或运行状态
将C6连接在电脑同一局域网上，当按键按下时C6执行向局域网内9号端口广播带有要开机电脑网卡MAC地址的幻数据包来激活电脑
（当电脑开启了网络唤醒后，网卡会在关机的时候用非常低的功耗来接收数据并激活电脑）
#include <WiFi.h>
#include <WiFiUdp.h>
#ifndef STASSID
#define STASSID "***"
#define STAPSK"***"
#endif
#define port 9
const char* ssid = STASSID;
const char* password = STAPSK;
WiFiUDP Udp;
bool isWarn=false;
void setup() {
pinMode(D2,INPUT_PULLUP);
Serial.begin(115200);
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.mode(WIFI_STA);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
}
void loop() {
if(!digitalRead(D2)){
if(!isWarn){
int i=0;
char mac={0x04,0x7C,0x16,0x5A,0xD5,0x8C};
char pac;
char * Address = "192.168.1.255";
int Port = 3333;
for(i=0;i<6;i++)
{
pac=0xFF;
}
for(i=6;i<102;i+=6)
{
memcpy(pac+i,mac,6);
}
Udp.beginPacket(Address, Port);
Udp.write((byte*)pac, 102);
Udp.endPacket();
}
delay(500);
}
}
将C6的D2与GND引脚短接，电脑响应开机（这里的延时非常小最多1秒左右）如果唤醒失败，首先确保自己的电脑主板支持唤醒（现在的主板一般都是支持唤醒功能的），其次确保UDP广播端口/MAC地址正确，其次电脑的BIOS设置允许唤醒开启/网卡的魔术包唤醒功能开启。
这里C6需要和电脑在同一局域网下，如果再将C6接入物联网平台例如阿里云/Blynk等即可实现远程唤醒电脑
本来外壳模型计划用莫嘉的1元CNC活动加工的 ，但模型不符合活动的要求，~~在修改修改吧
