【摘要】 让我们看看基本的基于Python的I2C函数,这些函数经常用于Raspberry Pi上的I2C通信。在python中开发Raspberry Pi I2C通信程序时,我们可以使用SMBus库包,它对访问I2C设备有很大的支持。因此,我们应该使用apt数据包管理器为Python添加SMBus支持,sudo apt-get install python-
本文参考http://www.instructables.com/id/Raspberry-Pi-I2C-Python/all/?lang=zh作者AntMan232 In this instructable, I will explain how to use I2C on the Pi, with the examples of the CMPS03 compass module and SRF08 Ultrasonic range, using python. I will explain right through installing the OS...
sudo apt-get install python-smbus 1. 基于Python的I2C函数 导入SMBus 要使用SMBus Python模块访问Raspberry Pi上的I2C总线,请按如下方式导入SMBus模块。 import smbus 创建SMBus类的对象以访问基于I2C的Python函数。 = smbus.SMBus(I2C port no.) I2C port no:I2C端口号。即0或1 Example – Bus = smbus...
