In the previous chapters of this book, you interfaced with devices using GPIOs, I2C, and SPI. You used AsyncTasks to perform hardware interfacing in background threads, and you explored how to structure an app to interact with those threads.
In this chapter, you will bring all of these concepts together to create a circuit that uses all three interfacing methods, and you will explore an app that uses all the interfaces together to make a complex system.
In this chapter, we will cover the following topics:
Building the complete interface circuit
Exploring the final example app
