WaveShare 7.5inch e-Paper HAT(電子ペーパー)をとりあえずRaspberry Piで動かす(ネット接続直後から)
#/bin/bash
# Timezoneの設定(GUI使わずコマンドにて)
sudo raspi-config nonint do_change_timezone Asia/Tokyo
# Raspberry PiのSPIを有効にする(GUI使わずコマンドにて)
sudo raspi-config nonint do_spi 0
# 再起動
sudo reboot
#/bin/bash
# Pythonでe-paperを動かすのに必要なライブラリ、解凍用コマンドなど
# Raspbian stretch
#sudo apt-get -y install python-dev python-smbus python-imaging build-essential p7zip-full
# Raspbian buster
sudo apt-get -y install python-dev python-smbus python-imaging build-essential p7zip-full
# WaveShareサンプルプログラム実行に必要フォント
sudo apt-get -y install fonts-wqy-microhei
# WaveShareのサンプルをダウンロードして展開
