custom raspberry pi board

Recently, the company came to a Raspberry Pi board, is a drawback, although only the size of the slap, but perfectly formed! The optical USB port has 4, also has the HDMI port, the network port and the microUSB port, the power supply only needs a 5V charger, namely the general Android Charger can give him power. But it's such a small

Guide to Getting StartedNow let's connect the LEDs to the hardware devices that have WINDOWS10 IoT Core installed and create an application to make them blink.Load a project in Visual StudioHere we find the routines here, which are available in C + + and C # versions. This tutorial only covers versions that use C #. Copy the project folder to disk and open it in Visual Studio.Then check your Windows IoT device and make sure the remote debugging feature is turned on (debugging), and you can refer

Automatic Logon 2. automatically run the startx startup Window System 3. After the window system is started, it automatically runs the custom program (generally the main interface of the application)
