法克啊城榛，本來(lái)我的底線是要自己建網(wǎng)站的。态兴。狠持。各種原因沒(méi)有成功只好在簡(jiǎn)書(shū)上寫了。瞻润。喘垂。
這篇文章是宗旨是怎么用arduino IDE來(lái)給ESP8266寫程序。ESP8266是我最近發(fā)現(xiàn)的很黑科技的一個(gè)東西绍撞。首先正勒，他繼承了WIFI功能，本身也有GPIO之類的傻铣，這些以前的模塊都能做到到是也沒(méi)有什么了章贞，但是價(jià)格非常之便宜，淘寶只需要25塊錢非洲，比普通的Arduino還要便宜一些鸭限。而最diao的是他只要安裝一個(gè)插件，就可以直接用Arduino IDE寫程序怪蔑，就像是給Arduino寫程序一樣里覆。很多Arduino的庫(kù)也可以直接使用。
首先缆瓣，幾乎所有的部分都是來(lái)自于 Adafruit的網(wǎng)站
恩喧枷，然后需要把Arduino升級(jí)到1.6.4以上。
這里開(kāi)始可能電腦要翻墻弓坞，但是如果的電信的網(wǎng)絡(luò)好像也可以不翻
選擇這里preferences偏好設(shè)置
在那個(gè)文本框輸入http://arduino.esp8266.com/stable/package_esp8266com_index.json
選擇boards manager
搜索esp8266隧甚，然后點(diǎn)擊安裝
之后對(duì)話框下面會(huì)有一個(gè)進(jìn)度調(diào)，要下載大約6m的文件渡冻，但是速度很慢戚扳。
之后就可以把我的代碼拷進(jìn)來(lái)，整體界面和processing很像
點(diǎn)擊工具族吻，然后按照我的選擇帽借，端口選擇最下面的一個(gè)
然后就可以像給Arduino寫程序一樣寫了。
燒寫
這時(shí)候要拔掉控制板的220v插頭超歌。
燒寫程序的時(shí)候要先把控制板查到usb口上砍艾，然后在插口旁邊有兩個(gè)按鈕，先按住標(biāo)有flash的按鈕巍举，然后按住標(biāo)有reset的按鈕脆荷，板子上的藍(lán)燈會(huì)閃爍一下，然后點(diǎn)擊arduino上的upload或者下載按鈕。
UPDATE:
做了一個(gè)閃電云蜓谋，然后拿回來(lái)以后不知道為什么就不能用了梦皮，直接接引腳是有用的，用usb供電就不行桃焕，用萬(wàn)用表量了一下VCC有一個(gè)限流電阻好像是斷了剑肯。用杜邦線短接以后就行了。
然后不知道為什么現(xiàn)在燒程序不用想以前那樣按按鈕了观堂。退子。。
然后這里是天氣云（只能實(shí)現(xiàn)一個(gè)天氣類型的展示）的代碼
