以太网W5500上传多路传感器数据到Yeelink~

wasdpkj

采用了Microduino W5500以太网模块~功能是读取三个模拟口值，通过序列依次传到Yeelink

继W5100、W5200和W5300之后一款全新的全硬件TCP/IP协议栈网络芯片，这款芯片具有更低功耗与工作温度，及改良工艺，是嵌入式以太网的最佳选择方案；

规格

• 通信协议
  • 支持硬件TCP/IP协议：TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE
  • 支持8个独立端口（Socket）同时通讯
  • 内嵌10BaseT/100BaseTX 以太网物理层（PHY）
  • 支持自动协商（10/100-Based全双工/半双工）
    
  
  

• 工作特性
  • 支持掉电模式
  • 支持网络唤醒
  • 支持自动应答（全双工/半双工模式）
    
  
  

• 更新速率
  • 支持高速串行外设接口
  • 内部32K字节收发缓存
    
  
  

• 接口特性
  • TTL 电平输入
  • 单电源供电: 3.3V；
  • 不支持IP分片
    
  
  

状态指示

把库名改一下，就不用删掉原来的库了吧

microduino的东西做工好、体积小。就是价格太不亲民，让人又爱又恨。

也要删除，调用的语法会冲突

学习了。。。。。谢谢

你笑的好甜

非常感谢~
