You can use the following online tool to generate the code for any 7-segment display pattern or number you need to display in your project, it’s a very handy tool.ħ-Segment Display Code Generator Online Tool That’s the trade-off you’ll have to decide on, depending on your project case. On the other hand, the 7-segments display units are larger in size and could be easily seen by users from a greater distance. A user can see clearly the LCD display from a distance no more than 1 meter. The LCD display will give you more digits with less price per digit. LCD Display Interfacing to PIC16F877 Microcontroller And it’ll be your decision to chose one over the other. And at some point, you’ll find out that an LCD module would have given you more display digits at the same, or less cost. Moreover, adding many 7-segments comes at a cost indeed. However, in many situations, it won’t be enough and you’ll need to add more digits and of course, you can’t reserve 7 io pins for each one of them! In a previous tutorial (7-Segments display interfacing), I’ve demonstrated how to interface a single 7-Segment display unit to display a single-digit number. *Affiliate Links Disclosure: links will make me a small commission at no additional cost to you* Component Name Buy On 1 PIC18F2550 Add 1 BreadBoard Add 1 Multi-Digit 7-Segment Display Add 1 Potentiometers Add Resistors Kit Add Add 1 Capacitors Kit Add Add 1 Jumper Wires Pack Add Add 1 LM7805 Voltage Regulator (5v) Add 1 Crystal Oscillator Add 1 PICkit2 or 3 Programmer Add 2 9v Battery or DC Power Supply Add Add Add Required Components For This Tutorial Qty. Without further ado, let’s get right into it! First of which is a 3-Digit counter and the other is a 3-Digit ADC result display. And you’ll create a couple of simple projects to test things out. I’ll briefly introduce the phenomenon called “persistence of vision” and how we can use it in embedded systems to trick the human eye by multiplexing displays in order to reduce the pin-count required to drive these output 7-segment display units.īy the end of this tutorial, you should be able to implement your own multi-digit 7-segments display controller. In this tutorial, we’ll be discussing how to interface multiple digits 7-Segments display with pic microcontrollers, or any other MCUs, generally speaking.
