MicroPython动手做（27）——物联网之微信小程序

1、微信小程序

小程序的一种，英文名Wechat Mini Program，是一种不需要下载安装即可使用的应用，它实现了应用“触手可及”的梦想，用户扫一扫或搜一下即可打开应用。全面开放申请后，主体类型为企业、政府、媒体、其他组织或个人的开发者，均可申请注册小程序。微信小程序、微信订阅号、微信服务号、微信企业号是并行的体系。




微信小程序是一种不用下载就能使用的应用，也是一项创新，经过将近两年的发展，已经构造了新的微信小程序开发环境和开发者生态。微信小程序也是这么多年来中国IT行业里一个真正能够影响到普通程序员的创新成果，已经有超过150万的开发者加入到了微信小程序的开发，与我们一起共同发力推动微信小程序的发展，微信小程序应用数量超过了一百万，覆盖200多个细分的行业，日活用户达到两个亿，微信小程序还在许多城市实现了支持地铁、公交服务。微信小程序发展带来更多的就业机会，2017年小程序带动就业104万人，社会效应不断提升。




2017年1月9日，张小龙在2017微信公开课Pro上发布的微信小程序正式上线。2018年2月，微信官方发布公告称：已对涉及假货高仿、SQ低俗和违规“现金贷”等超过2000个微信小程序，进行永久封禁处理。2019年8月9日，微信向开发者发布新能力公测与更新公告，微信PC版新版本中，支持打开聊天中分享的微信小程序。

他的文章会一直在留言里更新的

谢谢，学习了

2、打开微信搜索“掌控板物联网”小程序进行授权

微信授权并一键登录

添加掌控板，给掌控板取个名字，填上掌控板的mac地址

这里我添加了二块掌控板

3、登录mPython X 软件
编程软件登陆名要与手机微信登陆的帐号一致。曾经使用一个帐号登陆myphton X，用另一个手机号注册的微信号小程序查找，始终是设备不在线。说白了就是程序登陆的帐号要与微信号相同。

4、登录小程序“掌控板物联网”

好吧，这也算是一种创新的更贴

mPython X 实验图形编程

尝试好多次，我的掌控板终于能够“在线”了。

但是阅读连续性会降低，还是建议直接在一楼更新完

添加应用——这里添加了“控制RGB灯”

pATAq 发表于 2020-6-3 09:21
但是阅读连续性会降低，还是建议直接在一楼更新完

谢谢老师，级别太低，还是初级，要赚积分呢，呵呵

添加组件——这里添加了“开关”和“按钮”，计二个

组件调整为二个按钮，开灯键值设置为1，关灯键值设置为0

拖动按钮至合适位置并保存
