We have posted many articles about using Nextion to work with Arduino. But maybe you don’t know how to use it with Raspberry Pi. This post I’m going to teach you how to achieve it. There are just 5 steps.
Step 1: Install Segnix
Follow the “Readme.md” instructions of github, install Segnix to Raspberry Pi.
Step 2: Disable Serial
Login Raspberry Pi.
Then input below commands to disable the serial:
sudo raspi-config
————> 8 Advanced Options ————> A8 Serial ————>NO
Step 3: Software Preparation
Just to make it simple, here we use the button example in our Nextion library.
segnix CompButton CompButton.ino
Copy the button .tft file to SD card, then update Nextion with the SD card.
Step 4: Hardware Preparation
Connect Nextion display with Raspberry Pi with Dupont line as follows:
GND ----- GND
VCC ----- 5V
TX ------- RX
RX --------TX
Step 5: Run the program
Input below command in Raspberry Pi to start running the program:
sudo ./CompButton
Touch click the number button in Nextion display, the number will increase 1 by every click.
