Using videos and displays in projects
It's one thing to just plug an HDMI monitor into the mini HDMI port on your BBB and get a picture. In many cases, this is may be all you care about for a project. However, for bona fide embedded or mobile scenarios where you need a display, using the HDMI option can be overkill; your needs are low power, small form factor, and just enough display to convey basic information.
In this section, we will take a look at two other options for display: a mini OLED display available as a breadboard-able PCB and a custom BBB cape designed with a very small LCD panel.
Hooking up a mini OLED
In this recipe, we will take a look at a very small 1.3 inch OLED display with a resolution of 128 x 64 pixels. It has a monochrome screen, which means that we will not be watching Lawrence of Arabia on this device. Instead, we will explore some methods for basic control and input and take a preliminary peek at typical design choices for embedded devices.
The nice thing about...
