Pocket Mdm | Router in your pocket-Dev board for OpenWRT

Another week, some more and new creations. Pocket modem, a sweet and simple, yet handy, board so designed for one who want to use it as normal router Wifi enabled with b/g/n networking capabilities, 1x WLAN and 1 x Lan Port, and it’s also for developers who want to dive into Router Software development using OpenWRT or similar router OS platforms. A sleek hassle free development board for OpenWRT. This is the teaser of the board right now and looking forward to get the boards done in small quantity. If you want some of the boards to be ready, do let contact me.

I will be adding up soon once i get few boards done( assembled ). The board is designed carefully by keeping high Speed signals and USB lines in mind, hence controlled impedance lines runs on this double layer board. Ethernet PCB guidelines and USB 2.0 standard PCB design guide lines are been followed to make this working. It will come with Integrated Magnetics Rj45 connectors from Hanrun which is an alternative for cost cutting, yet, better space utilization on board is achieved, by not placing separate magnetics on the board.

Raspberrypi to monitor

This is one of my weekend work i carried out and still working. This is a Raspberrypi shield on which many sensors from various vendors can be placed.

Over the shield you have the above listed sensors, mostly Humidity and Temperature sensors. Along with that there is an arrangement for ADC interfacing with Raspberrypi on 3.3v TTL levels. Basically, you can connect your Current Sensors to this terminals, 4 of them and can get current of voltage at any given instance.

Nokia Asha 501 Application

Nokia Asha 501 Application | Trying to sync Facebook contacts to system contacts. This was my initiative at one of the weekends where i was wondering to sync my facebook contacts to the system contact feature, went to store and searched for such applications, but didn’t find any as such, If you guys know about such application do post or share it for rest of us, else i was pushing this as a side project to have an alternate basic phone-contact application in that phone apart from system pre-installed app.

Basically, this post is not in detail how to get started with Nokia Asha 501 Application, but a brief explanation how this project started and going where. For getting started please check out this well documented section from nokia itself.

Getting Started with Win32 APIs + OpenGL

Getting Started with Win32 APIs + OpenGL A small quick / jump start over win32 application in C If you are looking out to get started up with windows GUI based application development in C programming language. This is one of those post which is best for you to go through and jump start with your application. In current scenarios, web technologies and web app are the mainstream focused solutions, but still, existing systems which are windowed application types, are mainstream investment sector. Metro UIed Apps came and almost replaced all those windowed application but for commercial or been a commercial product to be, app stick to be a windowed application. Anyways, lets not catch up this as debate, but lets get started with win32 application development in no time. Setting up the environment IDE, libraries…

To set up your environment to get started with win32 application, lets have a very user friendly which has code auto completion feature and much more which helps developer to speed up its application development practice. You can pick one from the below

• Visual Studio Express 2013 for Windows Desktop (Recommended)
• Codeblocks
• Bloodshed Dev C++ IDE
• even you can get the ms c, c++ compiler to develop win32 apps,Any other which you are comfortable with

Once you are done with the installation with your IDE or compilers, you are ready to go for creating your new project.

Nordic Smart Bluetooth Low Energy

Smart Bluetooth Low Energy Technology has buzzed out the whole world and specially between electronics enthusiasts and hobbyists audience. Many 3rd party vendors came up with its bare minimum modules so developers and Designers lets get started with there other code task.

Bluetooth® Smart is the intelligent, power-friendly version of Bluetooth wireless technology. While the power-efficiency of Bluetooth Smart makes it perfect for devices needing to run off a tiny battery for long periods, the magic of Bluetooth Smart is its ability to work with an application on the smartphone or tablet you already own. Bluetooth Smart is an application-friendly technology supported by every major operating system. The technology costs less and offers flexible development architecture for creating applications to bring everyday objects like heart-rate monitors, toothbrushes, and shoes into the connected world and have them communicate with applications that reside on the Bluetooth Smart compatible smartphones, tablets, or similar devices those consumers already own.

BLE Development boards

• TI CC2540/CC2650
• Bluegiga BLE112
• RFDuino
• uBlox BLE
• Blueradios BLE

All the above boards are having there own pros and cons, for now i am not going into the details, do look in the datasheet for more details. For now i will work with nordic semiconductor’s NRF51 BLE modules, and this page will walk you through to get started with NRF BLE. If you are looking for a guide to getting started with NRF BLE then you are at right place.

Development kit to buy

Basically for getting started

Softwares to download!?

Do not misplace yor key!

Firstly, create an account in nordic semiconductor’s web site. Next, do add the Product key under your product section. this way you will be unlocking your product, now you can download the softwares. Few softwares are allowed to dowload for free too.

• nRF51822 Development Kit Software Downloads, required software are listed below…(or pick the latest versions of the same so mentioned below…)
  
• Code: S110-SDS, software bluetooth stack specification.
• Code: S110-SD-v7, software bluetooth stack aka SoftDevice.
• Code: nRF-MCP-xx, Master Control Panel with Master emulater, pick that which suits your OS architecture.
• Code: nRF51-BLE-Driver, nRF51 Bluetooth Smart GATT/GAP driver for Windows.
  Used to set up and interact with BLE on an nRF51 device with connectivity firmware and S110 SoftDevice.
• Code: nRF51-SDK-zip ot the installer, nrf software development kit which includes all examples and libraries.
• Code: nRF51-Tools, nRF51 toolset installer (JLinkARM, JLink CDC, nRFjprog, and mergehex)
• Code: nRFgo Studio Win xx, pic the best suited for your machine’s architecture. Used to Upload hex to board.

Another interesting thing will be, integrating gcc with eclipse to start developing BLE applications, a proper guide you can get from the same page where you see the list of softwares to download, under APPLICATION NOTES, it is been linked. Now, keep those software with you somewhere safe, although you can download them again as you have unlocked that product.

Integrated Development Environment

Eclipse, keil or IAR!

• Download keil non-free version which has code size(32KB) limitations but to get things started you can use this.
  

Install the keil, and you will find the same examples are also provided in the “Device” folder inside the keil installation folder. onces installation is done you need to setup the hardware now.

//Some basics
//------------------------------------------------
//
//GPIO
//APIs
nrf_gpio_cfg_output( [pin number] ); Set the pin number as output.
nrf_gpio_cfg_input(); Set the pin number as input with pull up or no pull up or pull down.
nrf_gpio_pin_clear(); Clears the pin.
nrf_gpio_pin_set(); Sets the pin.

– Pin mapping/ numbering
– Pin counting from zeroth port, pin maps from 0
– Example P0.0 will be counted as pin 0, and so on.

• Nordic devZone
• For more work around which i carried out in dev zone is here. apart from this you can also work on your own ideas and can get help from this community.

Plus points with this SoC

Related to Smart Bluetooth

• You do not have to get familiar with any RTOS .
• Pre compiled bluetooth stack as hex file constantly released for slave, central and both slave and central. Central, means the BLE stack which acts as master.
• No constrain of OTP, one time programming.
• Comes with industry standard Cortex-0 8 bit MCU, amazingly low power consumption, upto 500nA claimed. If you configure it correctly on circuit and also do write a best firmware on top of BLE stack then it does touch 500nA in shut down mode. But most of the time it stays in power_manage();

HMVC Codeigniter Jump Start

Updated a repo where basic setup of Codeigniter to have HMVC arrangement, so you can jump start your project. This repo comes with default controller and a basic default module sub mvc for testing purpose. The repo has netbeans project files too.

WeatherPilot

A device or an arrangement, from which we can get information about air quality, temperature, humidity, wind speed and direction. With data so collected, can be now send to some end point or at terminal where we can store it, can retrieve from any database or time series database…

A device which can sense and obtain values like temperaturehumidity air quality like CO and CO2 lux , planning more or less about what more sensors i can put like anemometer. Will update on this as the board gets fab. More about it in repo.
