timer-interrupt The same as 5. and 6., but now using one of the timer peripherals. It uses the 'update' interrupt, triggered when the timer counter overflows. When, like in this case, you only use one or two interrupt sources, you can do without a vector table. Instead, you can us...
微型气象站主要实现对居住或办公场所内温度、湿度、大气压强和光照等气象变化实时监测,更为准确呈现屋内或办公区域的气象变化,便于直观感知。 微型气象站由检测端和接收端两部分组成。检测端连接传感器,将传感器测量数据上报至腾讯云物联网平台。在腾讯云物联网平台建立数据流转规则,将检测端上报的数据以MQTT报文形式转发至...
