What is important is that we need to add two devices, one being the CPU temperature and the other being the GPU temperature. here we need to get two important things, that is, the destination for writing the program message POST (applied by ourselves)

it has been a great success.In order to make scratch with the Gpio interface of the Raspberry Pi, the first thing you have to do is to open the program, enter the editing interface, choose to start the Gpio server. Then you can use the broadcast block to identify the Gpio interface you want to use. In the above, these two broadcast blocks point to Config19out and Gpio19on respectively. And the Gpio 19 is p

Starting with the Windows IoT Core 14986 release, Microsoft has added the Cortana voice assistant feature. Before, we could only use local speech recognition, and we needed to write the application to download it to the device. From now on, Microsoft has integrated the Cortana voice assistant from the system level, enabling users to start Cortana and interact with Cortana in real time with system settings. Let's try the process of using Cortana as a Windows IoT core device with
