PiSpy,In ., we saw that the Raspberry Pi 2 is powerful enough to compile its own kernel. This was necessary to install the rpidma kernel driver so that the . command could allocate and use DMA for data capture. In this chapter, we turn our attention to the . tool itself and learn how to use it. We also take a high-level look at how it works.

Debouncing,The . of attaching a push button to a GPIO input is deceptively simple. Use a push button and a couple of connections and some simple software to read a 1 or a 0, right? After all, it’s digital input and just 1s and 0s. It all seems so elementary, yet things are more complicated than that.

組裝

Class GPIO 1,The library class GPIO provides a very simple API to work with the Raspberry Pi GPIO hardware in a C++ program. Using this library class, you can immediately work to define your application rather than rewrite or adapt the code.
