Figure 3.3.4 illustrates the pin out for the C0216CiZ, as well as the connection
diagram to establish reliable communications between the display and the
microcontroller. It is necessary to provide separate power chains for both the
backlight, as well as the onboard display logic. The device itself is very simple to
interface with, and has a pre-programmed slave device address to listen for. All
of these communications are handled by software on the microcontroller that
emulates the functionality of a hardware serial controller. For this reason, it was
important to evaluate the rise and fall time, and the stability of the signal as it was
being driven high and low by software. If the signal did not meet the timing
specifications established by the display manufacturer, then the digital logic on
the display would not be able to recognize a proper high to low, or low to high
transition.
