首先,在Raspbian OS的命令行下安装 (1).blinka基础库 (2).servo (3).I2C (4).PCA9685的环境依赖(某些权限不够的情况下需要在命令行前添加sudo, 例如 sudo pip3 install xxx,另pip3表示使用Python3.x的包) #install basic adafruit basic circuit control module pip3 install adafruit-blinka #Always upda...
Python Installation of PCA9685 and ServoKit Libraries You'll need to install the Adafruit_Blinka library that provides the CircuitPython support in Python. This may also require enabling I2C on your platform and verifying you are running Python 3.Since each platform is a little different, and Lin...
