adafruit-circuitpython-ds1841 1.0.3

简介

Maxim DS1841 I2C对数电阻的电路Python库

依赖关系

此驱动程序依赖于：

• Adafruit CircuitPython
• Bus Device
• Register

请确保CircuitPython文件系统上的所有依赖项都可用。 下载很容易实现 the Adafruit library and driver bundle。在

从PyPI安装

在支持的GNU/Linux系统上，比如Raspberry Pi，可以在本地安装驱动程序from PyPI。要为当前用户安装：

pip3 install adafruit-circuitpython-ds1841

要在系统范围内安装（在某些情况下可能需要这样做）：

要在当前项目的虚拟环境中安装：

mkdir project-name &&cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-ds1841
