There are two important aspects that we have not covered:
- How to select the pin to connect the peripherals to
- How to identify the pin name
Regarding the first aspect, in Raspberry Pi 3 and Intel Edison, but in general for all the boards, the pins do not provide the same features. In other words, we cannot connect the peripherals to a pin by choosing it randomly. We have to select the pin according to the peripheral specifications. In this context it is important to know the pinout of the boards so that we can identify the right pins for our peripherals.
The second aspect is relevant when we want to develop an Android Things app that will run on different boards. As we said in the previous chapter, from the code point of view, this is not a problem because the Java language at the base of Android Things SDK guarantees us that we can run...
