Extra resources for Android Hardware Interfacing with the BeagleBone Black

Sample text

Open a second file explorer window and navigate to the c:\PacktHAL\prebuilt path. Change to the Android NDK window, right-click anywhere within the white space of the file list in the window, and select Paste from the context menu. This will copy the contents of the spi header file directory into your NDK header files. Your Windows NDK installation now has the extra header file that it needs to build PacktHAL. Multiplexing the BBB pins As accessing hardware resources follows the same process under Android as it does under Linux, it is important to understand how the Linux kernel configures device drivers and allocates them to particular pieces of hardware.

The broad availability of Android-based devices has generated a large amount of interest in developing software applications, or apps, that target Android. It has become easier to develop Android apps. Eclipse Android Development Tools (ADT) allows app developers to prototype software and then execute that software within an emulated Android device environment. However, the emulated device differs from real hardware in subtle (and sometimes dramatic) ways in terms of speed and appearance. Luckily, a powerful and low-cost hardware platform is available that allows you to quickly and easily test your apps on real hardware: the BeagleBone Black.

You only need to copy the file into your NDK installation prior to building PacktHAL. 4 KitKat, and API level 19 is the highest level supported by this version. You will be building all of the examples in this book for API level 19. Each API level has a different set of headers in the NDK, so you must add the missing headers to the include/linux directory for API level 19. If you decide to build apps at lower API levels, you can repeat the following steps to add the additional header file to any of the other API levels that you wish to.
