ubiq_uitous communication, wearable and multimedia systems

This is work in progress - and also targeting Arduino integration.

Found time to successfully work with BTstack and TI MSP430 hardware again.

So many months without a post here. Have a look at my Flickr stream to see what happened in between.

Now testing interaction between iPhone 4S and Arduino via Bluetooth Low Energy (BLE) using TI CC2540.

I modified the device - so it can be programmed via its serial bootloader - which is very useful on OSX or Linux.

The housing, LCD, USB connectors make it a nice basis for both experiments as well as long lasting dedicated usage.

Just click on the photo for more information.

Input can be done via Bluetooth, programming using OpenGL ES.

Due to the better toolchain support for PIC32 on Windows, I checked the means of porting BTstack using tools available on Windows.

Here is a whole set of screenshots.

I hope to run btstack on Arduino hardware. Not sure yet about whether to use a stock avr-libc program or even FreeRTOS, Femto OS or NutOS.

Programs can be compiled with a gcc toolchain bootstrapped from scratch on OSX.

The shield may use either Bluetooth or WLAN for communicating with the outside world.

It is also used for trying to run btstack ( http://code.google.com/p/btstack/ ) on the Arduino.

Please just click on the photos for more details.

Can be done via I2C.

Work in progress - more information to follow.
