Interfacing Displays

In the realm of embedded systems, the ability to communicate with the outside world through visual feedback is fundamental. Displays, ranging from simple LEDs to complex graphical screens, serve as essential interfaces between machines and humans, offering a window into the operations of microcontrollers. In our modern society, it seems like displays are everywhere. Everything from coffee makers to stereos and watches now have intelligent displays on them. Modern smartphones also have a large display, and when designing devices, except for the most basic devices, your users will expect some sort of visual feedback. This chapter delves into the intricacies of interfacing displays with PIC microcontrollers, and we will look at using various display technologies including liquid crystal displays (LCDs), organic light-emitting diode (OLED) displays, and touch displays.
