adafruit-circuitpython-il0398 1.2.2

简介

为IL0398驱动电子纸显示屏的CircuitPython displayio驱动程序

依赖关系

此驱动程序依赖于

• Adafruit CircuitPython

请确保所有依赖项都在CircuitPython文件系统中可用。这可以通过下载Adafruit库和驱动程序包轻松实现。

从PyPI安装

在支持GNU/Linux系统（如Raspberry Pi）上，您可以从PyPI本地安装驱动程序。在此处安装。为当前用户安装

pip3 install adafruit-circuitpython-il0398

为系统范围安装（在某些情况下可能需要）

sudo pip3 install adafruit-circuitpython-il0398

在当前项目的虚拟环境中安装

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-il0398
