Tiva C Projects: Seven Segment Display With Tiva C Launchpad

How to interface seven segment display with tiva C launchpad

Let`s do it

• Tiva C board
• Breadboard
• Jumpers
• Seven Segment Display

• Connect pin A on 7Seg with PB0 on Tiva C
• Connect pin B on 7Seg with PB1 on Tiva C
• Connect pin C on 7Seg with PB2 on Tiva C
• Connect pin D on 7Seg with PB3 on Tiva C
• Connect pin E on 7Seg with PB4 on Tiva C
• Connect pin F on 7Seg with PB5 on Tiva C
• Connect pin G on 7Seg with PB6 on Tiva C
• Connect common pin on 7 seg with 3.3 V on tiva C

There are two types of seven segment display:

• Common anode: you should connect the common pin with 3.3V
• Common cathode: you should connect the common pin with ground

In this project, we used a common anode seven segment display so the common pin should be connected with 3.3V and when we want to turn on a specific led we should let its pin as low

To turn on A LED, PB0 must be LOW (common anode 7 segment display)

To turn on B LED, PB1 must be LOW (common anode 7 segment display)

Note: If we use common cathode display, the corresponding pin should be HIGH to turn on the LED.

In the above table, there are the binary and hexadecimal formats for each digit in 7 seg

for example for digit 0 in 7 segment, we should turn on all LEDs on 7 Seg except G LED and DP LED

0 <- 11000000 -> 0xC0

and so on for all digits.
