SEVEN SEGMENT DISPLAY COUNTER PIC1. F8. 77. A MICROCONTROLLERSEVEN SEGMENT DISPLAY COUNTER USING PIC MICROCONTROLLER,In this tutorial, you will learn what is seven segment display? What are applications of seven segment display? We have used two 7- segment displays in this project to display a 0- 9. Let’s move forward by defining seven segment display. Code for this project is written using Mikro C for pic. What is seven Segment Display?
Seven segment display is regarded as the most basic and simplest electronics. Simplest, because its working is easy to understand and its interface with the controller is quite straight- forward. Seven segments, as the name suggests, consist of seven LEDs organized in a specific pattern. Each LED is known as a segment and it is assigned a name from . Another additional 8th LED named as .
In common anode display, the positive pins of all the LEDs are tied together to form the common pin which needs to be provided a . In common cathode display, all the cathode connections of the LEDs are tied together which forms the common pin that needs to be grounded.

To display a counter of 0- 9. PIC1. 6F8. 77. A in this project, one for tens and the other for ones. The seven pins of each segment are connected to the seven pins of PORTB and PORTC, starting from LSB, via a resistor of 5. R. Each pin represents an alphabet which switches the corresponding LED bar on and off with respect to the code. As per the connections shown in the circuit diagram, alphabet .
Same pattern is followed for the ones segment connected to PORTB. We have chosen both 7- segments with a common anode display.

As such, the common pin of both 7- segments are connected to Vcc. C- CODE FOR TWO 7- SEGMENT COUNTER INTERFACED WITH PIC1.
F8. 77. A : Write the following code in the Code Editor Window of mikro. C Compiler: /* 7 Segment display counter 0- 9. PIC1. F8. 77. A*/void delay(); void main(). The values defined within the brackets corresponds to digits from 0 to 9. But these are not the hex values of the actual digits 0- 9.
- This circuit divided in three parts: sensor, controller and counter display. The sensor would observe an interruption and provide an input to the controller which would run the counter in up/down mode depending upon the.

These are the values that needs to be generated on the port pins for the corresponding digit to appear on the 7- segment. For example, to display . So, the port pins should give the output 0b. The inner . The program is executed infinite times until aborted. APPLICATIONSeven segment displays are vastly used in our daily life equipment, be it the digital clocks at our homes or the electronic meters at our work stations. It can be used as a countdown or a timer when playing games or in competitions etc. The basic calculators also uses a 7- segment display.
