Show weather reports OLED(SSD1306) with Raspberry Pi

Raspberry Pi Zero W Rev 1.1にinstallしたRaspberry pi OS 12 (bookworm) の動作確認です

OLED(SSD1306)に天気情報を流すPython scriptを書いてみた。

ベースのコードは、Adafruit_CircuitPython_SSD1306 の/examples/ssd1306_pillow_animate.py

# pip install adafruit-circuitpython-ssd1306

# pip install pillow

# git clone https://github.com/adafruit/Adafruit_CircuitPython_SSD1306

等

fontは、IPAフォントを使用

＃apt install fonts-ipaexfont
