下一阶段稍微棘手一些,因为它需要为第一个 Raspberry Pi 安装风扇。需要按照外壳说明将其连接到正确的 GPIO 端口以及第二个丙烯酸层。下一步是通过额外的浅支架将第二个 Raspberry Pi 放置到第二个丙烯酸层上。最后,将深支脚连接到第一层原来的四个支脚的头部。参见下图: 现在可以对第三层重复该过程。请记住将...

下期会介绍如何把红外线接收管接上去,并配置LIRC去接收遥控器的信号,从而实现用遥控器控制Raspberry Pi的目的。 参考资料: 面包板的使用 Drive a 16×2 LCD with the Raspberry Pi Raspberry Pi GPIO接口信息 题外话: 细心的同学在上图中可以发现我的Raspberry Pi的电源口附近有一个体积和样子都很违和的电解电容。

The GPIO of the Pi Zero is not pre-soldered, unlike other models of Pi. Soldering is a great skill to learn and the Pi Zero GPIO would be a great place to start. (Image credit: Tom's Hardware) If you can solder, then it is simple to add your own GPIO header pins. But, if...
一.Raspberry Pi的数据采集 本文采用Raspberry Pi 2B,有4个USB接口,一个Ethernet接口,一个HDMI接口,一个MicroSD插槽,一个3.5毫米音频插孔和复合视频,摄像头接口(CSI),显示接口(DSI),另外还有一个40Pin的GPIO接口。 我购买的淘宝链接: https://item.taobao.com/item.htm?spm=a1z10.5-c.w4002-11372085286.12....
Describe the bug Raspberry Pi 5's openwrt peripherals and 1 G network card do not work. The Raspberry Pi 5's fan doesn't work, as well as the rtc clock doesn't work, and the USB Gigabit NIC doesn't work. Only the HDMI, WIFI and Ethernet ...

Next you will create the InitDHT method, where you will either initialize the WiringPi library as well as set the GPIO pin that the DHT11 is connected to. You will also test to see if the WiringPi library is already initialized:
