To determine this you search the part number online and check the datasheet. Determining LED resistor value Our seven segment display will need resistors at each leg to prevent the LED’s from drawing to much current. A seven segement display is basicly just a bunch of LED’s wired together in one easy to use package.

Wiring a seven segment display can be a bit confusing, this guide aims to be a practical guide to get you started. Our datasheet tells us each LED has a maximum forward voltage of 20mA, so we use a little hdsp-503 to save the LED a bit, we’re picking Some displays have a DP dotted point and some don’t, check the datasheet to know which one you’re getting.

Using Ohms Law we can easily determine the resistance needed.

We need to put a resistor at each pin of this value to prevent the LED’s from blowing up. Common Cathode vs Anode We start by determining if our 7 segment display component has a common cathode negative side or anode positive side.

If we want the top LED bar of our segment to light up we first find out which port number is attached, lets say the top bar is connected to the 4th pin our our shift register we can write this in byte as: Referencing a digit is as simple as: Our seven segment display will need resistors at each leg to prevent the LED’s from drawing to much current.

If we would only put 1 resistor at the common pin for example the LED’s would get different amounts of current for every digit you’re trying to display, if you would only display the same digit every time you can get away by calculating the total current resistor value but because each LED in our case is individually addressable we need to put a resistor at each of them.

In our case a HDSP the part has a comon cathode. Creating your digits To create your digits we simply map the corresponding LEDs to hdsp-55003 byte.

These are the only 2 pins were all the LED’s are connected to. To create your digits we simply map the corresponding LEDs to a byte. We can also see in the datasheet that the common ground is located at Pin 3 and Pin 8.

We start by determining if our 7 segment display component has a common cathode negative side or anode positive side. In most datasheets this is mentioned in hdsp5-503 text, if it isn’t you can easily determine this yourself by looking at the internal wiring schematic of the part see image below where the LED’s are shown with their polarity, the direction the schematic symbol arrow is pointing to is the cathode negative side, datasheeet other side is the anode positive side.
