In our program, we will define a counter that counts from 0 to 99 and displays the counting on the two seven-segments connected as above.Д«elow is the program code, circuit picture and video.

In order to simulate the design file, open Proteus 8.6+ professional and open Calculator.pdsprj. Connect the power adapter and you are good to go. For convenience, the pin configuration of the 7 segment displays can be found here. The persistence of the seven-segments LEDs will cause it to stay illuminated after being disabled until it is enabled again in the next cycle. The 7 segment displays are common cathode, so the com ports will be connected to ground. You might think that this sequence will cause the seven-segments to blink as we enable and disable them, but in fact you will not notice this blinking. Write 1 to PORTC pin 3 (PC3) to enable the second seven-segment.Write BCD of the number we want to display on the second seven-segment on PORTC pins (PC4-7).Write 0 to PORTC pin 2 (PC2) to disable the first seven-segment.Write 1 to PORTC pin 2 (PC2) to enable the first segment.Write BCD of the number we want to display on the first seven-segment on PORTC pins (PC4-7).Now, according to the above schematic, in order to illuminate the two seven-segments at the same time, we need to follow these steps: In such case, we save around 10 pins, as we connect 2 seven-segments with only 4 MCU pins.

Modify the code by changing the display output at SD1 to SD2 without. In such case, we will add a BJT transistor between the cathode of each seven-segment and the ground and use the base of this BJT as an enable bit for each seven-segment as demonstrated in the schematic. View Lab 3 BASIC INPUT AND OUTPUT ( 7 SEGMENT CONTROL) - ver3.docx from ECE MISC at. Using the CD4511B IC allows us even to connect more than 1 seven-segment on the same 4 pins of the MCU. The input pins (A, B, C, D) take the input number as BCD and the output pins (a, b, c, d, e, f, g) are the 7 bits output that will be connected to the seven-segment as will be demonstrated in the schematic.ДЇor more clarity, the below table shows the inputs and corresponding outputs of the CD4511B: Hard wired The below diagram clarifies the input and output to the CD4511B. This is an easy to use IC that takes the number you want to display as an input in BCD (Binary Coded Decimal) format and outputs the 7 bits needed to illuminate the seven-segment with the desired number. Imagine that you want to connect 2 seven-segment devices to display the numbers (0-99), in this case, you will need to use 14 pins of the MCU I/O pins which may leave you in a shortage of pins for other external peripherals.ДЇortunately, there is a better way to do it, using the CD4511B IC (BCD to 7 Segment Decoder), shown in the below picture. However, this way is not efficient as it wastes a lot of valuable MCU pins.

The straightforward way to do that is to connect each pin from the seven-segment to a pin on the MCU and use the software to control the LEDs lighting and display the numbers we want. Interfacing 7 Segment Display with AVR Atmega32: In this tutorial, we will be using a common cathode 7 Segment display. In the case of aВ common cathode, all LEDs have a common ground and each has a different pin for the high voltage (Vcc). In common anode seven segment, VCC is common for all the LEDs and each has a different pin for the low voltage (that is ground). There are 2 types of seven-segment, that are вЂњ common anodeвЂќ and вЂњ common cathodeвЂќ.

2 pins represent a common ground to all the LEDs.

1 pin is the VCC for decimal point display at the lower right corner.

7 pins act as the Vcc for the 7 LEDs (1 pin for each LED, assuming that we are dealing with common cathode seven segment display).

So here is the diagram and the simulation file as well as the running output of the simulation.The Seven-segment consists of 7 LEDs arranged in a way that allows constructing a display of the numbers of (0-9). Most of the time when simulations are running in the Proteus, it means there are highly chances the code will be working in the real time as well. We selected the Proteus for this purpose due to its real time simulation nature and the ability to simulate Arduino code pretty well. Lets first create a simulation file to test our code in the Proteus. Simulation for 4 digit 7 segment shift register in Proteus So if you choose to add ULN between the shift register and the 7 segment display, you may need to choose common anode display instead of common cathode. This is the reason that we chooses common cathode display for this simulation. The most common buffer which is used with the shift register is the ULN2003. Although we preferred not to add any resister or any buffer while interfacing 7 segment with shift register but you may need to add few current limiting resisters and/or some buffer to handle the current requirements of the 7 segment.
