I have build an IMU consisting of an Accelerometer and Gyroscope that can provide 6DOF motion output results to pc. I use a serial COM port over USB interface to get data on pc and i can see the data through Hyper terminal.
Now what i want to do is control my mouse pointer with that data for demonstration purposes. I initially looked at GlovePIe application but it doesn't support serial com ports. So it would be great if anybody could advice or direct me to a possible solution.
I am doing something similar, controlling pc mouse with android phone. But I am using Bluetooth and the touchscreen as input. You can look into win32 api functions for controlling com port.
You can also you sockets to send coords over tcp/ip. Setting up Bluetooth/Sockets is fairly easy once you understand the api calls. Let me know if you need more assistance.
use C++ code to controll the pointer location. SetCursorpos(x,y).Enjoy

I am working on edge computing for IoT applications and expected to create a system that acts as a near edge computer with the use of a raspberry pi hooked up to a dht11 sensor. How do I send this data over to a computer that is at the edge? Ideally I want to use my PC as this device but I have no clue how to send this data over in real time.
So far I have created the circuit and can view the temperature and humidity readings on the raspberry pi in python. Unsure of what the next steps are - I don't want to send this data over to the cloud just yet.
Side note: I believe i may be missing knowledge regarding this but is the raspberry pi an edge device because it is hooked up to the sensor directly?
Any help is greatly appreciated.
You need to think this through a bit more. What will you do with the temperature and humidity data that you receive?
For example, if you're just experimenting and want to just see the readings in a console on your PC, you can use netcat to send the console output of your Python program from the RPi to PC. No SW development needed, they just have to be in the same network. Not particularly useful for anything else, either.
Otherwise you need to set up some client-server solution between the RPi and your PC. There's a ton of possible solutions, all depending on what you plan to do with the data. You can use MQTT, HTTP, a straight database connection (MySQL, PostgreSQL), etc. You have to supply both sides of the connection. The Python code on client side which connects and sends data; and the server side thing that accepts the samples and stores them somewhere. Plus all the networking, authentication etc.
Or you can just download the Python client libraries for your favourite cloud solution and set that up according to a tutorial. TBH, this sounds a lot less work to me.
Since we are still struggling with sending and receiving bluetooth data, we want to try a different way, ignoring bluetooth for now.
Is it possible to write a software, which Windows or Linux is recognizing as a Hardware Gamepad for simulating (so we only need to change the input of that tool to bluetooth input later)?
And if it is possible, what do I need to know for achieving that? Thank you!
(We are using C/C++)
I've received a project from someone that includes an Arduino (Uno) board with some sensors and lights with an USB cable and a documented protocol for communicating with this board through a COM port. It works fine with some existing code, but I need to port the whole project to a Windows RT environment using an ARM processor and including the Metro interface for the application. And it's going to be completely rewritten...
First of all, my Windows RT device does have an USB port so it can connect to the board. But the challenge is to communicate with the board to read out the sensors and manipulate the lights and I happen to have problems finding some useful libraries, tutorials or other information about how to make these work together.
This project works fine with other Windows versions, though. I just need something specific for Windows RT/ARM/Metro.
Currently it is not possible to do this on Windows RT, and here is an explanation why. As a work around I am using a standard full screen WPF application in combination with the Surface SDK for touch enable UI components. The obvious disadvantage here is that you cannot publish the app to the store.
I think that we should actually try it on a real machine instead of the rt. The surface rt is basically for documents and the internet.
You'd be better off trying all of this with a Toshiba 2032.

I am looking into what's the best method for getting external data (custom built hardware) and to intercept and process this data (programming language / tool), the cheapest and easiest and with the least learning curve.
Background:
I am a web dev.
External device will be switches, motion detection, velocity detection
Programming language: Delphy (which I don't know)? or C# (which I know for web dev) or other?
Anyone done anything like this before? Got any advice?
Any and all information is appreciated.

The easiest solution might be to use an Arduino.
It's :
cheap (~ 30$)
easy to program
easy to connect to your PC (it use an USB cable which emulate a serial connection)
have a HUGE community with tons of tutorials for doing whatever you want
Here is an example how to control a led using C#
Is there a way to use the iPhone as an interface device for a computer without actually having to code a driver? Being the owner of a sub-par game controller and realizing that it would be cheap and a good experience to try to roll my own, I have no idea where to begin on the PC side. I am capable of processing accelerometer and touch events on the iPhone and sending them over a network, but where would I begin on the Windows side? I'd prefer to not get as low level as a driver, but I want to be able to use the accelerometer as an analog input device and buttons on the screen as regular buttons. How should I go about this? If I have to write a driver, what would be a good reference/code sample to start with?
You don't need to write drivers as long as you handle the data being sent by the iPhone on PC. As far as where to begin on PC side, all you need to do is create a small program which listens for data on the socket. You can make that program in any language C, C++, Java etc. I had worked on a similar application as mentioned by you. On PC I used Java with Visual Studio IDE.
I believe this is similar to what Splashtop's Remote does (http://www.splashtop.com/remote/touchpad). They seem to use a network connection to accomplish this goal.
Also Joypad, same concept (http://getjoypad.com/).
