This is a complete code to print ADC value on a 4-digit seven-segment display in Mikroc for Pic compiler. Now, if we rotate the knob of POT according to increasing or decreasing resistance terminal, voltage also rise or fall on analog input pin (AN0). Connect one terminal with positive terminal of 5 volts, other terminal with ground and center terminal with ADC pin of PIC16F877A microcontroller. To provide, the analog voltage input to ADC channel AN0, we connected a variable resistor ( which is also known as POT ) to this pin.Ī potentiometer is a three terminal passive electronics device. In order to make a practical demonstration for displaying ADC value on seven segment display, we used one analog to digital converter channel ( AN0/RA0) of PIC16F877A microcontroller. This table shows the connections of PORTD of PIC16F877A microcontroller with A-G pins of the seven-segment device through 330ohm resistors. Make connections of PORTB with control pins according to this table. Also RB0, RB1, RB2, RB4 pins to control each 7-segment from out of four.

LED Blinking Example Pic Microcontroller ( Learn to use GPIO pins)įor this tutorial, we used PORTD of PIC16F877A to send binary pattern data to seven-segment displays.

For more information on how to use GPIIO pins of PIC16F877A microcontroller, check this tutorial: These resistors act as current limiting resistors. Therefore, resistors are used to make a connection between PIC16F877A and 4-digital seven segment display module. However, each GPIO pin of Pic microcontroller can provide 25mA current. This configuration will result in the display as shown in the figure below.PIC Microcontroller and 7 segment ConnectionsĪs you know that each display device consists of 7 LEDs and light-emitting diodes that are used in typical displays require about 10mA current to operate.

This configuration will result in the display as shown in the figure below.ĭigit 5: to display the digit 5 we need to turn on the segments a, c, d, f, g. This configuration will result in the display as shown in the figure below.ĭigit 4: to display the digit 4 we need to turn on the segments b, c, f, g. This configuration will result in the display as shown in the figure below.ĭigit 3: to display the digit 3 we need to turn on the segments a, b, c, d, g.

This configuration will result in the display as shown in the figure below. and turn off the LED segments a, d, e, f, and g. which would look like the figure given below.ħ-Segment Display Segments for all Numbersĭisplay combination of decimal numbers is given below.ĭigit 1: to display the digit 1 we need to turn on the segments b, c.

Suppose we want to display digit ‘0’, in order to display 0, we need to turn on “a”, “b”, “c”, “d”, “e”, “f”. We assume common cathode LED segment as our example. Each of the pins will illuminate the specific segment only. Working of 7-Segment Display (LED & LCD) Circuitħ LED segments of the display and their pins are “ a”, “b”, “c”, “d”, “e”, “f” & “g” as shown in the figure given below.

To illuminate any of the LED segments we need to provide logic ‘0’ to it. This terminal should be connected with Vcc or logic ‘1’ during its operation. The type of 7-Segment display in which all the anode terminals of 7 LEDs are connected together to form common anode terminal. To illuminate any LED of the display, you need to supply logic ‘1’ to its corresponding input pin. It should be connected to GND or logic ‘0’ during its operation.

In such type of 7-segment display, all the cathodes of the 7 LEDs are connected together to form a common terminal. There are two types of 7-Segment displays.
