Last night was the Cross Platform Iot Session at CTXUG in Cape Town. The turnout was absolutely amazing! Thank you to all for coming it was a really fun evening!
Roger Weiss from Aliens kicked off with an overview of Windows 10 Iot Core and a few demos. These demos featured some awesome use of Microsoft Cognitive services and also some nifty voice controlled home automation.
It was then my turn. Unfortunately Chris van Wyk couldn’t make it this evening. 🙁
The session featured
Visual Micro for Visual Studio
Visual Studio Code with Arduino Extension which is now Open Source.
Xamarin Forms and Xamarin.Android with Android Things 0.41 Preview
The new Xamarin Iot preview for Linux based devices
That was using Xamarin Iot on Visual Studio for the Mac (Preview). Xamarin Iot is also however available for Visual Studio 2017 on Windows (Preview 2.1) too. Below is the identical solution just running from Visual Studio 2017 on Windows. Have a look!
This is just a quick look at Xamarin Iot running on a Raspberry Pi Zero, this time on Visual Studio on Windows. More in-depth content coming soon!
This is a first look at the new Xamarin Iot functionality found within Visual Studio for Mac 7.1 Preview. I will dig much further into detail in future posts, but lets have a very quick look and it. I’m really excited about this addition to the already awesome Xamarin tooling!
A new project type has been added for Iot. This project type or template will create the solution and project needed to run on the Iot device.
What’s immediately apparent is the new run option for the Iot project type. There’s now a new item called “Manage Devices”
The Iot Device Manager allows all the connected devices to be managed. This setup is very similar to the Mac Agent used for iOS development with the Xamarin Visual Studio for Windows extension, however it will display all the Linux based devices running on the network. In this case and screenshot it’s a Raspberry Pi Zero running Raspian (Jesse). Configuring the device will allow remote deploys to the device from your Mac. This will require a user name and password of a user on the Raspberry Pi. This user will be used to connect to the Raspberry pi via SSH. Also note, SSH needs to be enabled on the Raspberry Pi for this to work.
Now you can start developing your Iot solution. What’s really awesome is, all the things you expect to work will just work. This includes break points and a full debugging experience. All this can happen wirelessly to a “headless” device.
The build and execution process is very similar to the Mac Agent when you do iOS development from Windows (Visual Studio) to a Mac. The difference in this case, it is from a Mac (Visual Studio) to a Linux instance (Raspberry Pi). On the very first execution, the mono run time will be copied over to the device. This will be used to execute the built app. The application itself and it’s “built code” is also synchronized with the Raspberry Pi. This compiled Iot app is then in turn executed on the device remotely.
Lets see it in action! Here is a simple example of the now standard Iot demo of a flashing LED, but running on a tiny Raspberry Pi Zero W. What’s really nice about this implementation is, it runs on devices that is not supported by other Iot platforms, like Android Things and Windows 10 Iot Core. It will run on the myriad of Linux based devices out there.
There is much more to show and tell. So there’s much more blogs to come on this topic! This will also include how Android Things and Xamarin Iot can work together to make cross platform Iot simpler.
