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 tim
There are several ways of getting GPIO input into your program. The first and simplest way is to check the input value at a point in time. This is known as 'polling' and can potentially miss an input if your program reads the value at the wrong time. Polling is performed in loops and...

GPIO.setmode(GPIO.BOARD) GPIO.setmode(GPIO.BCM) 如果在设置模式之前就分配引脚,那么Python会返回错误信息。 我个人更喜欢Broadcom编号模式。因为在这种模式下,哪些引脚是GPIO、接地或电源会更清晰。我还使用了GPIO扩展板来构建面包板原型,并且在该板上根据GPIO编号对每个引脚进行标记。 有人可能觉得板编号模式更容易...

In this article, we delve into the strategic application of "Python Libraries" - RPi.GPIO and PinPong, effectively manipulating the "Raspberry Pi GPIO" and "Raspberry Pi I2C" of the "Raspberry Pi".
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...
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...
For example, Linux File I/O, anything connecting to the GUI layer or low level hardware access commands will not work because Proteus does not simulate the Linux OS running on the Raspberry Pi. More technically, we support the low level rPi libraries detailed here. A huge number of Python ...
