Migrating an embedded Android setup: What could possibly go wrong? (Part 1)

2017-11-15T14:00:36+00:00

We migrated our embedded Android showcase to a new Version. In this five part series we document, what worked – and what went horribly wrong.

Android updates are rare, especially for development boards. We were running such a deprecated board once built to demonstrate our knowledge in embedded Android. Sinc

Android Sensor Integration Part 4: The Android Sensor Framework

2017-11-29T11:17:20+00:00

In this conclusion of our series we finally arrive at the Android Sensor Framework to which we are going to connect our ultrasonic range sensor.

Android Sensor Integration Part 3: HAL

2017-11-29T11:20:53+00:00

While Google gave the design of the kernel module into the hands of the hardware manufacturers they define a clear interface for the HAL.

In the previous parts of this series we had a look at how a kernel driver works. This time we continue to better documented areas. While Google gave the design of the

Android Sensor Integration Part 2: Sensor Readings

2017-11-29T11:31:08+00:00

In the second part of our series on Android Sensor Integration we will have a look at how to actually get readings from our SRF02 Ultrasonic Range finder.

Android Sensor Integration Part 1: Sensor Stack and Kernel Module

2017-11-29T11:35:51+00:00

This first part will take you on a walk through the integration of a proximity sensor into Android. We start investigating what occurs in kernel space.

Enhancing a Device Tree for ARM CPUs

2017-11-29T12:34:59+00:00

The Device Tree is supposed to revolutionize that by reading the hardware configuration from a data structure stored in RAM at startup.

Traditionally, the specific hardware configurations are described in so called board-description files and permanently embedded into the kernel during compilation, ma
