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...
Here is the Raspberry Pi 4 default GPIO pinout for the 40 pin J8 header. This is the configuration of the pins as you'll receive it when you first boot up Raspbian, or NOOBS with Raspbian. However, did you know that they are configurable? Ye...
从下面的GPIO口分布图可以得知,“2”口就是+5V,正好就利用它。 We can see that there are total 4 input pins: IN1~IN4, these 4 pins will be connected to 4 GPIO pins on Raspberry Pi. And we also need to provide a 5V power supply to the board, so where can we get this? Use the ...
Second I²C interface (3.3 V) (if pins are reconfigured in software) I²S interface (if pins are reconfigured in software) Handshake signals for the UART on the P1 header (if pins are reconfigured in software) P6: 2-pin 2.54 mm header expansion (header not fitted), providing an opti...

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...
