Raspberry Pi pin mappings

You need to know which physical header pins on the Raspberry Pi correspond to which pin numbers you access in your code. For example the pin 37 (second from bottom left pin) maps on GPIO 26. There is a very helpful document on the Microsoft web site that gives you the pin mappings, but for convenience I’ve also summarised the information in the following table:

GPIO#	Power-on Pull	Alternate Functions	Header Pin
2	PullUp	I2C1 SDA	3
3	PullUp	I2C1 SCL	5
4	PullUp		7
5	PullUp		29
6	PullUp		31
7	PullUp	SPI0 CS1	26
8	PullUp	SPI0 CS0	24
9	PullDown	SPI0 MISO	21
10	PullDown	SPI0 MOSI	19
11	PullDown	SPI0 SCLK	23
12	PullDown		32
13	PullDown		33
16	PullDown	SPI1 CS0	36
17	PullDown		11
18	PullDown		12
19	PullDown	SPI1 MISO	35
20	PullDown	SPI1 MOSI	38
21	PullDown	SPI1 SCLK	40
22	PullDown		15
23	PullDown		16
24	PullDown		18
25	PullDown		22
26	PullDown		37
27	PullDown		13
35*	PullUp		Red Power LED
47*	PullUp		Green Activity LED

* = Raspberry Pi 2 ONLY. GPIO 35 & 47 are not available on Raspberry Pi 3.

Deploy hints for apps on Windows 10 Iot device

The deploy step to debug an application on Windows 10 Iot device (like Raspberry Pi) needs some attention. The first thing to do is select the “Remote Machine” in debug section of project properties and than set the address to the IP address of your Raspberry Pi, and set the Authentication Mode to “Universal (Unencrypted Protocol”). Next, press F5 on your project. This will install your project onto the Raspberry Pi and start debugging.

When debugging stops the application is again in the device. But if it is a background application it is not running. Should be able to see it in the web management portal under the “Apps Manager” option. You can use this to start and stop an application; configure it to start automatically at boot up, and to uninstall the application.

W10 IOT cannot install Microsoft.NETCore.UniversalWindowsPlatform

I developed a background application for Windows 10 Iot to run on a Raspberry Pi but when I create the new project I get the following Error:

If I manually add the last version of Microsoft.NETCore.UniversalWindowsPlatform package and than I start Build I get a lots of errors.

The temporary fix that works for me is the following :

• replace in your .csproj file

<ItemGroup>
  <!-- A reference to the entire .Net Framework and Windows SDK are automatically included -->
  <None Include="project.json" />
</ItemGroup>

with

<PropertyGroup>
  <RestoreProjectStyle>PackageReference</RestoreProjectStyle>
</PropertyGroup>

• and after manually add the Microsoft.NETCore.UniversalWindowsPlatform package from nuget manager

And finally I can Build my app.
