贝壳物联智能开关，更新修正tmr.alarm问题 代码部分 8266纯粹是个坑，搞了3周，陷了无数次。写在2020疫情之后，武汉加油，中国加油！！！下面随便聊个坑： nodemcu-build官网 的固件代码部分已经更新，特别是tmr.alarm计时（钟表）函数，原来的结构多简单，现在生生的代码编译不过去，只能用18年12月以前的固件。可是那些封装好的有些不是你需要的，好尴尬。现在使用了动态tmr函数重新修改封装。----------2020.4.5

固件下载nodemcu站点

共init.lua config.lua两个文件，烧录固件看附件。 1老版固件 包含以下模块： file , GPIO , HTTP , MQTT , net , node , PWM , SJSON , timer , UART , WIFI

2新版固件 包含以下模块： file,gpio,http,mqtt,net,node,pcm,pwm,rtcfifo,rtcmem,rtctime,sjson,tmr,uart,wifi,tls
