使用Python 控制 GPIO 使用GPIO Zero 库可以轻松地用 Python 控制 GPIO 设备。该库在 gpiozero.readthedocs.io 上有全面的文档说明。 有关GPIO 硬件的信息,请参阅 GPIO 硬件。 LED 控制 以下示例代码可控制连接到 GPIO17 的 LED: from gpiozero import LED from time import sleep led = LED(17) while True...
RPi.GPIO runs a second thread for callback functions. This means that callback functions can be run at the same time as your main program, in immediate response to an edge. For example: defmy_callback(channel):print('This is a edge event callback function!')print('Edge detected on cha...
cd RPi.GPIO-0.x.xx sudo python setup.py install (2)测试程序 说明:led灯闪烁(分别接pi-01 和pi-11,11作为输出) importRPi.GPIO as GPIO importtime defblink(times, delay): GPIO.setmode(GPIO.BOARD) GPIO.setup(11, GPIO.OUT) whiletimes>0: if0==times%2: GPIO.output(11, GPIO.HIGH)#or ...
GPIO.setup(12, GPIO.IN, pull_up_down=GPIO.PUD_UP) GPIO.setup(12, GPIO.IN, pull_up_down=GPIO.PUD_DOWN) 要读取输入引脚的当前状态,请使用: GPIO.input(12) 您可以使用output函数来将输出引脚设置为高电平或低电平,如下所示: GPIO.output(11, True) GPIO.output(11, False) 为引脚命名 如果您将...
gcc led.c -o led -lwiringPi 1. 运行程序: Run the program: ./led4 可以看到LED开始闪烁了 可能遇见的问题: GPIO测试编译时出现了这个问题 官方论坛上说是少装了库的原因 安装这几个库: i2c-tools,libi2c-dev ,python-smbus ...

Performance is about the same as Python version, around 21 kHz square wave is generated: C: Maximum performance The Raspberry Pi Wiki gives a niceC code examplefor true hardware-level access to the GPIO. The interfacing is slightly more difficult, but code isn’t too bad. I took the examp...
GPIO stands for General Purpose Input Output. The Raspberry Pi has two rows of GPIO pins, which are connections between the Raspberry Pi, and the real world. Output pins are like switches that the Raspberry Pi can turn on or off (like turning on/off a LED light). But it can also send...
GPIO.setmode(GPIO.BCM) We save and exit the Editor (CTRL + O, CTRL + X) and execute the Script. sudo python ampel_skript1.py To abort the Script, press CTRL + C. InPart 2we build the Phases of a Traffic Light.
