While the controller lets you control all the GPIOs, DACs and ADCs available on your platform, you might not be interested in controlling all of them at the same time. To over come this, you can now use an option called "QuickCtl". By using this option, you will be able to use condensed version of the controller app. Using this option allows you to pick the pins that you want to control.
This post is going to be about my first experience with the awesome new "YRDKRX63N" kit that I received recently from the Renesas electronics Singapore. This kit was sent to me as prize for the recently held "Renesas RX Robot Challenge" on facebook.
Recently, my brother got selected for a "Beagle Bone radio challenge" road test by element14. As part of this challenge, the selected individuals had to build a working radio using the components provided by element 14. I've decided to help my brother a little with a feature called "scan". This post is going to be how we got the "scan" feature to work. This feature scans the available FM channels.
Tools used for analysis:

The first thing to do is analyze few samples that the rtl_fm program outputs. The rtl_fm is the program that can be used to tune into FM channels. Below is a typical command line that can be invoked to tune into any FM channel.
This one is still related to the my previous posts. This time around, I have added features that I had promised in my earlier posts. The usage of the software remains mainly unchanged. What has changed is the way in which the firmware is written. The firmware now uses polymorphism to make it easier to adapt the communication frame work to different hardware platforms (The selected hardware platform should support C++ as a programming language to use this approach). The current implementation makes use of polymorphism at two different places
(a) For the implementation of the communication channel (UART/serial protocol in our case)
(b) For implementing the functions required for accessing the digital and analog peripherals
blog post is the first in series (hopefully, there will be more) of
tutorials on the EvoPrimer dev kit from Raisonance. These tutorials
will mainly concentrate on usage of the circle OS. This tutorial
assumes that you already know how to create a simple Circle OS
project. If you are not aware of the procedure to do so, you can
follow this tutorial to learn about it.
this tutorial, we will see how we can create and use a tool bar under
Circle OS. Toolbars are the widgets that appear on the top of the
this tutorial, we will build a simple game of gears, papers and
scissors (I could not find a rock icon in Tango image library :p).
The game logic itself is simple, the CPU makes a random selection of
an object, either a rock(gears), paper or scissor and compares
against the user selection, selected via the tool bar.
