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 your Raspberry Pi.
Step 2: Disable Serial
Log in 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 insert SD card to the Nextion SD card slot(make sure there is only one tft file in SD card), power up Nextion, the project installation will be automatically proceeded.
Note: Store only one tft file in the SD card, and the resolution of tft file must be in accordance with the resolution of your Nextion TFT. Your SD card should be in FAT32 format and less than 32G. If failed to program with SD card, view this post.
Step 4: Hardware Preparation
Connect Nextion display with Raspberry Pi with Dupont line as follows:
GND ----- GND
VCC ----- 5V
TX ------- RX
Step 5: Run the program
Input below command in Raspberry Pi to start running the program:
Touch click the number button in Nextion display, the number will increase 1 by every click.
