注意：如果您在樹莓派上安裝了 Ubuntu 作業系統，請進行如下組態：

• 在 /boot/config.txt 加入 enable_uart=1

• 在 Ubuntu系統的文件 /boot/firmware/cmdline.txt中刪除

console=serial0,115200（類似於在樹莓派系統中文件/boot/cmdline.txt）

• 運行以下命令關閉序列控制台：

sudo systemctl stop serial-getty@ttyS0.service && sudo systemctl disable serial-getty@ttyS0.service

• 請確保您已安裝python 序列庫 pyserial，而不是來自 apt 的 python-serial。

• 建立 udev file (/etc/udev/rules.d/50-tty.rules),並加入以下內容：

• KERNEL=="ttyS0", SYMLINK+="serial0" GROUP="tty" MODE="0660"
  KERNEL=="ttyAMA0", SYMLINK+="serial1" GROUP="tty" MODE="0660"

• 運行以下命令多載 udev 規則：

sudo udevadm control --reload-rules && sudo udevadm trigger
