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...
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...
