Pins RB0 – RB6 are connected to the A – G of the display. 3 inch quadruple digit multiplex common cathode display. We have used Common Cathode Seven Segment Display in this example. Each display is turned on above this rate and our eyes will think that the display is turned on for whole the time. If the frames change at a rate of 25 ( or more) frames per second, human eye can’t detect that visual change. This technique is based on the principle of Persistence of Vision of our eyes. The simplest way to drive Seven Segment Display is by using a driver or decoder and are available for up to 4 displays. Alternatively we can drive more than one Seven Segment Display by using a technique called ‘Multiplexing’. This is waste and not economical to use lot of pins of a Microcontroller just for display. ![]() Thus we actually need Microcontroller with 42 output pins. ![]() This could depend on hardware errors (wiring and/or connections to PIC), or on delays wrongly calculated. 'Black blocks' usually mean that the display has not been initialized at all. Lets assume that we need 6 digit display, ie we need 7 segment * 6 Display = 42 pins. RE: PIC18F4550 & LCD 16x2 Tuesday, Aug8:16 AM ( ) 0. But real time applications like Digital Clock, Calculator, Digital Watch requires 3-6 seven segment displays. ![]() When a Seven Segment Display is interface with PIC Microcontroller it needs minimum 7 pins to display a value.
