arduino: 3月 2015

剛開始使用enc28j60起server,

扒文找到的都是說設定一個與你自己內聯網沒衝突的ip,還要在結尾加句 goodluck!

左試右試,時得時吾得,搞左兩日才發現 ip 跟 mac address 有關,除了要設定跟你路由器相符合的 ip (192.168.0.xxx or 192.168.1.xxx or ...)外,mac address都會有影響,即系 ip 不一定是你設定的那一個,會隨mac arrdess 而改變,所以.......搞左我兩日,所以最穩陣的做法是,在setup() 加入顯示 ip

ether.printIp("My Router IP: ", ether.myip);

咁就吾使靠估喇

暫時找到最好用的http://smart-home.te.ua/aurduino-ethernet-modul-enc28j60-yly-web-upravlenyya-rele-arduino-webserver/?lang=ru

我都吾知注釋系乜文,好用岩用就得,
