编译OMG的DHT

编译的过程依然参考之前两篇OpenMQTTGateway的文章，但在编译的过程中遇到一个问题。

发现缺少Adafruit_Sensor.h所在的依赖库
在网页上搜索，发现这个函数所在的依赖库为Adafruit Unified Sensor
在网页上搜索了一下这个依赖库，大部分都是arduino的解决方法，这个依赖库的地址并没找到
在OpenMQTTGateway/platformio.ini下查看依赖库，发现Adafruit Unified Sensor就在依赖表中
unifiedsensor = Adafruit Unified Sensor@1.1.4

解决办法

每次重新编译前建议先清理环境

在OpenMQTTGateway/environments.ini的相关配置环境中添加依赖库即可

1
${libraries.unifiedsensor}

重新编译发现有其他依赖报错

1
fatal error: DallasTemperature.h: No such file or directory

按照上面思路在依赖库中找到相关依赖库并加入配置环境
dallastemperature = DallasTemperature

1
${libraries.dallastemperature}

问题解决

编译成功
