NodeMcu部分
1.init.lua
該部分使用到了httpServer，了解具體內容點擊項目地址下載httpServer.lua即可。
station_cfg={}
station_cfg.ssid="wifi"
station_cfg.pwd="xiaog123"
local color = {r = 0, b = 0, g = 0}
num = 12 --燈珠數量
ws2812.init()
wifi.setmode(wifi.STATION)
wifi.sta.config(station_cfg)
wifi.sta.connect()
tmr.alarm(1, 2000, tmr.ALARM_AUTO, function()
if wifi.sta.getip() == nil then
print('Waiting for IP ...')
else
print('IP is ' .. wifi.sta.getip())
tmr.stop(1)
end
end)
--寫出rbg的值
function ws2812Config(v)
buffer = ws2812.newBuffer(num, 3)
buffer:fill(v.b, v.r, v.g)
ws2812.write(buffer)
end
ws2812Config(color)
wifi.sta.autoconnect(1)
dofile('httpServer.lua')
httpServer:listen(80)
-- 從請求中取出rbg寫出
httpServer:use('/config',function(req, res)
color.r = req.query.r
color.b = req.query.b
color.g = req.query.g
ws2812Config(color)
print(buffer:get(1))
res:send('{"status": "ok"}')
end)
2.Html
由于NodeMcu內存比較小故第三方cdn加速的js和css

上傳部分
1.將html代碼保存為index.html
2.保存lua代碼為init.lua
3.下載httpServer.lua
將以上文件上傳至NodeMcu
