1 安装Luma.oled库

sudo apt-get install python-dev python-pip libfreetype6-dev libjpeg-dev
sudo -H pip install --upgrade pip
sudo apt-get purge python-pip
sudo -H pip install --upgrade luma.oled

注：如果你需要安装Python3的Luma.oled库的则按下面对应的Python3版本修改上面的命令进行安装。

pip ⇒ pip3
python ⇒ python3
python-dev ⇒ python3-dev
python-pip ⇒ python3-pip

如果安装Luma.oled库时出现红字错误，请继续执行命令重试，那是因为网络问题下载一个叫Pillow的库不成功。

2 连接显示屏和Pi

按照如下配置进行端口的连接，树莓源的端口信息可以到如下网址查看https://pinout.xyz/pinout/spi

3 修改代码

下载luma的示例代码https://github.com/rm-hull/luma.examples

我们以animated_gif.py为例，原始代码如下：

#!/usr/bin/env python
# -*- coding: utf-8 -*-
# Copyright (c) 2017-18 Richard Hull and contributors
# See LICENSE.rst for details.
# PYTHON_ARGCOMPLETE_OK"""
Displays an animated gif.
"""import os.path
from demo_opts import get_device

修改后的代码如下：

# PYTHON_ARGCOMPLETE_OK"""

主要是导入ssd1351，并将device调整为ssd1351. 显示效果如下：
