MicroPython Nextion library
MicroPython Nextion library
General
Ported library to interact with Nextion serial displays↗ (opens in a new tab), based on the ITEAD Arduino Nextion↗ (opens in a new tab) library.
Installation
Install required tools
Python3 must be installed on your system. Check the current Python version with the following command
python --version
python3 --version
Depending on which command Python 3.x.y (with x.y as some numbers) is
returned, use that command to proceed.
python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
Setup
Install package
Connect the MicroPython device to a network (if possible)
import network
station = network.WLAN(network.STA_IF)
station.active(True)
station.connect('SSID', 'PASSWORD')
station.isconnected()
General
Install the latest package version of this lib on the MicroPython device
import mip
mip.install("github:brainelectronics/micropython-nextion")
For MicroPython versions below 1.19.1 use the upip package instead of mip
import upip
upip.install('micropython-nextion')
Specific version
Install a specific, fixed package version of this lib on the MicroPython device
import mip
# install a verions of a specific branch
mip.install("github:brainelectronics/micropython-nextion", version="feature/add-mip-package-file")
# install a tag version
mip.install("github:brainelectronics/micropython-nextion", version="0.15.0")
For MicroPython versions below 1.19.1 use the upip package instead of mip
import upip
upip.install('micropython-nextion')
Test version
Install a specific release candidate version uploaded to Test Python Package Index↗ (opens in a new tab) on every PR on the MicroPython device. If no specific version is set, the latest stable version will be used.
import mip
mip.install("github:brainelectronics/micropython-nextion", version="0.15.0-rc1.dev29")
For MicroPython versions below 1.19.1 use the upip package instead of mip
import upip
# overwrite index_urls to only take artifacts from test.pypi.org
upip.index_urls = ['https://test.pypi.org/pypi']
upip.install('micropython-nextion')

Manually
Upload files to board
Copy the module to the MicroPython board and import them as shown below using Remote MicroPython shell↗ (opens in a new tab)
Open the remote shell with the following command. Additionally use -b 115200
in case no CP210x is used but a CH34x.
rshell --port /dev/tty.SLAB_USBtoUART --editor nano
Perform the following command inside the rshell to copy all files and
folders to the device
mkdir /pyboard/lib
mkdir /pyboard/lib/nextion
cp nextion/* /pyboard/lib/nextion
cp examples/basic/main.py /pyboard
cp examples/boot.py /pyboard
Usage
Use one of the examples↗ (opens in a new tab) to get started. Read also the examples README↗ (opens in a new tab) to find all supported elements
Credits
Big thank you to ITEAD Studio↗ (opens in a new tab) for the implementation of the Arduino library.
