小编给大家分享一下如何使用树莓源驱动128*128彩屏SSD1351,相信大部分人都还不怎么了解,因此分享这篇文章给大家参考一下,希望大家阅读完这篇文章后大有收获,下面让我们一起去了解一下吧!
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。
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
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:

# PYTHON_ARGCOMPLETE_OK
"""

import os.path
from demo_opts import get_device
from PIL import Image, ImageSequence
from luma.core.sprite_system import framerate_regulator
def main():
regulator = framerate_regulator(fps=10)
img_path = os.path.abspath(os.path.join(os.path.dirname(__file__),
'images', 'banana.gif'))
banana = Image.open(img_path)
size = [min(*device.size)] * 2
posn = ((device.width - size[0]) // 2, device.height - size[1])
while True:
for frame in ImageSequence.Iterator(banana):
with regulator:
background = Image.new("RGB", device.size, "white")
background.paste(frame.resize(size, resample=Image.LANCZOS), posn)
device.display(background.convert(device.mode))
if __name__ == "__main__":
try:
device = get_device()
main()
except KeyboardInterrupt:
pass
修改后的代码如下:

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