![]() ![]() We will define our array as a const integer since it will never change, we will need 10 unique arrays to store 0-9 values with 7 positions in each array, one for each segment. Multi-dimensional arrays may sound scary if you have never used one, however if you are familiar with basic arrays already then you can think of them simply as an array of arrays. One easy solution is to use something called a truth table, to store our truth table we will need to create a multi-dimensional array. ![]() A B C D E F G H I J L M N O P Q R S T X W Y Z & 1 2 3 4 5 6 7 8 9 0. That’s it, pretty simple right! Now how can we do this pragmatically? Download TrueType font for using on design projects and websites. It’s pretty obvious when you look at the diagram above where the name came from, any digit 0-9 can be shown by activating the right combination of 7 segments.

WHERE IS THERE A SIMPLE SEVEN SEGMENT digital FONT I found one here: Just download it and right-click then choose 'Install'. Luckily this display is a lot more capable than the vacuum fluorescent and 7-segment displays of the past, we should be able to overcome this dilemma with some simple code.įirst things first before we can write any code, we first have to understand the basic operation of a 7-segment display. The only problem, I was using a 128×64 OLED driven by a SSD1306 driver. I had a project come up recently where I needed to display some numbers that looked like an old 7-segment display. ![]()
