【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-smbus 基于Python的I2C函数导... 让我...
http://www.instructables.com/id/Raspberry-Pi-I2C-Python/all/?lang=zh作者 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, to ensure tha...
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...

Copy Codepython i2ctest.py You should see a sawtooth wave appear on the DAC output. If you connect an oscilloscope, you should get an image like the one shown in the C++ example. Note that Python is much slower than C/C++! The period of the sawtooth wave in the C++ example was aroun...

当使用 C SDK 创建 LED 闪烁应用时,有几种选择。第一种是查看 SDK 文档并按照说明进行操作。第二种是使用预设的 Docker 容器来自动安装所有必要的工具,以便开始使用。第三种选择是手动安装工具链和 Raspberry Pi Pico 示例代码,包括: Git Python 3
先不说质量,仅从数量和布局上看,比linux上的组织有规范。从示例上可以看到已经涵盖了spi,i2c,serial,gpio这些常见外设,也给出流行的node.js和python等上手资料。 更多的example可以在github里找到。拆摸Boy已经把它check下来到本地。 可以看出从点灯到OLED显示,到蓝牙,到摄像头,都有相关示例,还有比较流行的ADXL345...
