4 cards from this section. Quick, good the night before a test.
What is a common cathode display?
Think about what happens when you connect all negatives together.
Why do we use multiplexing with displays?
Consider how quickly we can switch between several things.
What segments are illuminated to display the number '4' on a common cathode display?
Think about which segments create the shape of '4'.
True or False: A common cathode display requires all anodes to be grounded to light an individual segment.
Remember how power is supplied to the segments.
Design a scenario where using common cathode displays would be more beneficial than common anode displays. Consider factors like power consumption and control complexity.
Think about ease of use in different projects.
Create a table comparing the control signals required for common anode vs. common cathode displays in terms of ease of use and complexity.
Consider programming and number of connections needed.
