1/15/2024 0 Comments Led 7 segment display fontWe use logic 1 through a current limiting resistor to forward bias the individual anode terminals a to g. In common cathode seven segment displays, all the cathode connections of LED segments are connected together to logic 0 or ground.Types of Seven Segment Displays:Īccording to the type of application, there are two types of configurations of seven-segment displays: common anode display and common cathode display. Seven segment displays must be controlled by other external devices where different types of microcontrollers are useful to communicate with these external devices, like switches, keypads, and memory. Therefore, Boolean expressions for each decimal digit that requires respective light-emitting diodes (LEDs) are ON or OFF.
