You can test whether your GPIO pins and LEDs are working by building the circuit below. You can use any resistor over about 50Ω. The LED is connected directly to the GND pin and the 3V3 pin via the 330 Ohm resistor, and should light up. Be sure to connect your LED the correct way...
目标是拥有一个单一的通用平台和一组功能,用于跨多种语言访问 Raspberry Pi GPIO。 WiringPi 本质上是一个C 库,但 Ruby 和Python用户都可以使用它,他们可以分别使用“gem install wiringpi”或“pip install wiringpi”。 WiringPi 使用自己的引脚编号方案,此页面说明了 WiringPi 如何为您的GPIO 引脚编号。 Wiring...

GPIO 是 General Purpose Input Output 的缩写,即“通用输入输出”。 Raspberry Pi 有两行 GPIO 引脚, Raspberry Pi 通过这两行引脚进行一些硬件上的扩展,与传感器进行交互等等。 Raspberry Pi B+/2B/3B/3B+/Zero 引脚图 简单的讲,每一个 GPIO 引脚都有两种模式:输出模式(OUTPUT)和输入模式(INPUT)。输出模式...
The gpiozero package contains a database of information about the various revisions of Raspberry Pi. This is queried by the pinout command-line tool to output details of the GPIO pins available. gpiozero 包带了一个数据库,其包含了各个版本树莓派的信息。可以通过调用 pinout 命令行工具来输出 GPIO...

GPIO代表“通用輸入/輸出”,正是這些引腳讓Raspberry Pi發揮了其功效。因為這些引腳沒有特定的功能,所以可以設置為某個專用功能,例如控制信號。 設置為輸出的GPIO引腳可以提供3.3V(高電平信號)或0V(低電平信號)的電壓。當設置為輸入時,該引腳可以讀取相同數值的電壓。
