Interfacing 7 Segment Display with Raspberry Pi Circuit Connection👇👇👇👇
Follow @circuit_digest

The connections, which are done for Interfacing 7 segment display to Raspberry Pi, are given below. We have used Common Cathode 7 Segment here:

PIN1 or e —————— GPIO21

PIN2 or d —————— GPIO20

PIN4 or c —————— GPIO16

PIN5 or h or DP ———- GPIO 12 //not compulsory as we are not using decimal point

PIN6 or b ——————GPIO6

PIN7 or a ——————GPIO13

PIN9 or f —————— GPIO19

PIN10 or g —————- GPIO26

PIN3 or PIN8 ————-connected to Ground

So we will be using 8 GPIO pins of PI as an 8bit PORT. In here GPIO13 is being LSB (Least Significant Bit) and GPIO 12 being MSB (Most Significant Bit).

Now, if we want to display Number “1”, we need to power segments B and C. To power segment B and C, we need to power GPIO6 and GPIO16. So the byte for ‘PORT’ function will be 0b00000110 and the hex value of ‘PORT’ will be 0x06. With both the pins high we get “1” on display.
