How do dynamic or multiplexed 7-segment displays work?
Multiplexing 7-segment displays is a powerful way to reduce the GPIOs your microcontroller needs to drive multi-segment displays. We got a helpful animation to show how this works conceptually!
To see the whole video comparing static and dynamic 7-segment displays and how you can drive one of these 7-segment dynamic (or multiplexed) displays with a Microchip microcontroller, check out the video here: • Part 6. 7-segment LED Indicator | Emb...

7-segment LED displays are, by electronic standards, ancient technology. But they are so useful that they're still used all the time! In the full tutorial, we learn about dynamic or multiplexed multi-character 7-segment displays that allow you to use a relatively small amount of GPIOs to control many characters. We review how it works and then create a C-based program to show how to use it in practice. We hope you enjoy learning about microcontrollers and embedded systems using the PIC18F14K50 as an example!
