简介

CircuitPython的BLE MIDI服务

依赖关系

此驱动程序依赖于：

• Adafruit CircuitPython

请确保CircuitPython文件系统上的所有依赖项都可用。 下载很容易实现 the Adafruit library and driver bundle。在

从PyPI安装

在支持的GNU/Linux系统上，比如Raspberry Pi，可以在本地安装驱动程序from PyPI。要为当前用户安装：

pip3 install adafruit-circuitpython-ble-midi

要在系统范围内安装（在某些情况下可能需要这样做）：

要在当前项目的虚拟环境中安装：

mkdir project-name &&cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-ble-midi
