【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...
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 AI检测代码解析 Example ...
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...
Connect the boards as in the picture below. Connect the Pico to Raspberry Pi or PC. Open the Lesson-21 LCD1602 I2C example by Thonny, you need to first save the RGB1602.py to Pico and then run the Choose_Color.py file. The LCD will change color every 5s. If you run the Discolorat...
LCD1602 I2C Experiment Connect the hardware according to the figure below, connect the Micro USB connected to the computer, open the python file in the demo Lesson-21 LCD1602 I2C in Thonny, save the RGB1602.py file as a Raspberry Pi Pico, and run the Choose_ Color.py to see a different...
i2cget -y 1 0x20 0x20: address of PCF8574 IO extension chip. Control PCF8574 IO Based on Libraries Some examples are given in this part to explain how to write data via I2C bus using BCM2835, WiringPi, sysfs or Python Libraries. These programs are used to write data to a PCF8574 ...
Connect Pi to the monitor, keyboard, and mouse. Start Pi and then sign into Raspberry Pi OS by using pi as the user name and raspberry as the password. Select the Raspberry icon > Preferences > Raspberry Pi Configuration. On the Interfaces tab, set SSH and I2C to Enable, and then selec...
It allows the LCD display to operate with the Raspberry Pi Pico W. The code should be copied and pasted into Thonny, and then saved to your Raspberry Pi Pico W, to the same folder that contains you Python code. It MUST be saved with file name lcd1602.py 1 2 3 4 5 6 7 8 9 10...
A user can single step debug any flowchart program with its Arduino C++ source code or Raspberry Pi Python code. A user can convert any flowchart program into an Arduino or Raspberry Pi sketch and then type some additional code in either C++ for Arduino or Python for Raspberry Pi. ...
