My life with Android :-). Tuesday, December 30, 2014. Integrating an Android smartphone application with the BLED112 module. My conclusion with the RFDuino adventures. Bluegiga's BLED112 USB dongle. The BLED112 implements the same API (called BGAPI, check out Bluetooth Smart Software API reference. Click here to download the Android client. And the PC server. In this exercise, we will implement the Current Time Service. Grab a Windows machine, download the Bluegiga SDK. Usb 3-2: Product: Low Energy Dongle.

My life with Android :-). Friday, February 7, 2014. RenderScript in Android - the parallel version. In the previous post I promised to revisit the parallel case. The big promise of RenderScript is to exploit parallelism among different CPUs, GPUs and DSPs in the device at no additional cost. Once the algorithm is properly transformed into parallel version, the RenderScript runtime grabs whatever computing devices are available and schedules the subtask automatically. The problem with DTW. The other paral...

My life with Android :-). Tuesday, March 11, 2014. Beyond RenderScript - parallelism with NEON. My last post about the parallel implementation. Of Distributed Time Warping (DTW). The example program can be downloaded from here. The relevant functions are in jni/cpucore.c. There are 3 implementations, processNativeSlow, processNative and processNativeNEON, each is progressively more optimized than the previous one. The processNativeSlow and processNative functions are in C, in processNativeNEO...Let's tak...

My life with Android :-). Wednesday, April 22, 2015. Infrared imaging with Android devices. In this post, I will present an integration of FLIR Lepton Long-wavelength Infrared Camera. The prototype system presented here needs a relatively long list of external hardware components and it is also not trivial to prepare these components. This list is the following:. An Android phone with Bluetooth 4.0 capability. I used Nexus 5 for these experiments. A BeagleBone Black card with an SD Card 4GB. Fortunately ...

My life with Android :-): My first steps with command-line development tools

My life with Android :-). Sunday, December 23, 2007. My first steps with command-line development tools. As, I guess, most of the prospective Android developers, I started my Android experience by going through the Tutorial. This tutorial assumes Eclipse. Based development environment. Many people love Eclipse but I am kind of old-fashioned and I prefer command line development tools. Somehow I feel myself more in control of what is happening during development. :-). List of devices attached. Command, th...

And demonstrated that RenderScript implementation of the same algorithm can be 2-3 times faster than Java. How can a "script" be so fast? In order to understand this speed difference, let's see how the RenderScript fragment is executed. The example program is available here. Int32 t s2len = 0;. Int32 t *d0;. Int16 t *signal1;.
