I was reading about the prospects of IoT and wan to start with it. So I want to buy a board. The 4 options are specified on the website. But there is this new board named C.H.I.P. I would like to know whether I can use this? If not, please guide which one is suitable to buy. Can someone please suggest a few resources from where I can learn?
Currently Windows 10 IoT Core only supports 4 boards:
Raspberry Pi 3
Raspberry Pi 2
MinnowBoard MAX
DragonBoard 410c
You can see a comparison of the boards here: https://developer.microsoft.com/en-us/windows/iot/boardcomparison
I would suggest going with the Raspberry Pi 3 as it has built-in Wi-Fi and Bluetooth. You can purchase the board separately or get one of the many Starter Kits. The kit is a good option if you're just starting out. It will include the Raspberry Pi and many accessories to start learning and building projects.
Adafruit Starter Kit: https://www.adafruit.com/product/3058
SparkFun Starter Kit: https://www.sparkfun.com/products/13826
Microsoft Store (board only): https://www.microsoftstore.com/store/msusa/en_US/pdp/productID.334851400
Just remember that Windows 10 IoT Core requires a Class 10 microSD card. Some of the kits may have slower cards.

I need a Mac to write a native Codename One interface for iOS. I would like to use it in the future for the same purpose. I need to be able to open with Xcode the native code generated by the build server, add the implementation in Objective-C of the native methods and test the code on my iPhone X, to connect to the Mac via usb.
I found the following refurbished computer, I would like to ask you a secure confirmation that it goes well for the above purposes, before buying it:
Model MacBook Pro 13″ (MacBookPro9,2) - A1278 - MD101LL/A - 2012
Intel Core i5 3210M "Ivy Bridge" 2.5GHz "Ivy Bridge" processor with turbo boost up to 3.1GHz
Installed Ram 8 GB PC3-12800 (1600 MHz) DDR3 SO-DIMM
Intel HD Graphics 4000 integrated video card - 1.5GB of shared video memory
Installed Hard Disk Drive 500GB SATA 2.5″ HDD
13.3 inch (diagonal) LED backlit display - 1280×800 pixels
Operating System macOS 10.15 Catalina
Keyboard Layout QWERTY US - International
2x USB 3.0, 2x Thunderbolt, 1x SD-card slot, 1x Jack 3.5″ Devices
Right now seems OK, my one serious concern is the SATA disk and not SSD. Up until recently I used the 2013 version with 16gb, SSD and i7 which is still a great machine (screen broke in a fall on hard tile floor).
I can't tell if it will work well in the future but for now the important line is:
Operating System macOS 10.15 Catalina
That's the latest. So it will be able to run the latest xcode which should be compatible for Codename One development for a while.
Since this is an 8 year old machine and Apple is transitioning to ARM devices don't expect more than 2 years from this machine though.
Another option you can consider is a Mac mini. They are often an amazing value for the money, even when new.
I just searched about an open-source library to use of my project to build a voice controlled robot and found CMUsphinx. but my robot will build on ARM based microcontroller and I have not Linux or Windows on it. Is it possible to use CMUsphinx on ARM based microcontrollers? How can I do it?
Is there any better options instead of using CMUsphinx on ARM uControllers?
Actually, you can use a variant of CMUSphinx, known as PocketSphinx, on ARM devices. Most resources focus on Raspberry Pi, as it's a very popular ARM target.
The instructions for installing on a Raspberry Pi are here:
http://cmusphinx.sourceforge.net/2016/06/should-you-select-raspberry-pi-3-or-raspberry-pi-b-for-cmusphinx/
There's a voice assistant for Raspberry Pi that uses CMUSphinx:
http://cmusphinx.sourceforge.net/2014/04/jasper-personal-assistant-for-raspberry-pi/comment-page-1/
And, there's a recent blog post about running on the Raspberry Pi here:
http://cmusphinx.sourceforge.net/2016/06/should-you-select-raspberry-pi-3-or-raspberry-pi-b-for-cmusphinx/
Is it possible to use CMUsphinx on ARM based microcontrollers?
No, it's not possible to use CMUSphinx on microcontrollers.
but my robot will build on ARM based microcontroller
Consider using more powerful CPU, it will help you with other tasks like navigation or network sync as well.
I have recently ordered a Raspberry Pi 2 Model B but after doing some research I am unsure whether or not it comes with a native C library for the GPIO. I have seen that there are several 3rd party libraries such as WiringPi, but I would've preferred to use a native one if it exists. This website seems to indicate that it does exist.
Edit: By native, I mean a library that comes out of the box with the Pi, either was officially implemented by the Foundation or Linux on release of the product or at least has very low-level access to the pins, and has been thoroughly tested on this model.
My experience with micocontrollers and electronics is limited to ATmega Controllers, programmed in C and some tranistors and displays, nothing too special.
However, I want to get my hardware one step smaller, and want to start using the BLE Nano for all Bluetooth related projects.
For a first example project I'd like to create a bluetooth enabled temperature sensor with a small display.
As Display I chose the 0.96" OLED Display from Adafruit, which features a SSD1306 Controller. Adafruit offers a library for it (here: https://github.com/adafruit/Adafruit_SSD1306 ) but it is not clear to me, if I can use this library together with the BLE Nano.
I realized that I was to fixated on using the arduino library for my "normal" project.
There are other libraries out there, for example on github, which are written in plain c and should therefore be easier tot adapt for different platforms.
The Adafruit library is an Arduino library, so you would need to register your BLE Nano module in order to gain access to Red Bear's pre-release Arduino library - See the "Using Arduino" section of the "Getting Started with nRF51822" page
i coded a java applications that takes the pictures of a webcam that is attached to the pc. For that i use the lti-civil java-api. It works fine! This api uses a shared library -libcivil.so- for jni access to several native libs. The libcivil.so exists for linux 32/64bit osx and windows. But i want the application to run with raspberry pi which has arm-architecture.
My question is: is it possible to recompile the libcivil - shared lib for arm-architecture? iam not familiar with c++ so i don't know if it is possible in any way.
i found a way to obtain webcam images with java on a raspberry pi. I use the v4l4j library. It's a jni wrapper for the v4l2 api. It handles direct access to the /dev/video interface under linux. There is a way to compile it for the raspbian linux-port and it works great. But the raspberry seems to be too slow (5-8 fps and hight latency - about 300-500ms). But this is another thing. Now iam waiting for the hackberry or gooseberry... =)
compile v4l4j on raspberry pi how-to:
