树莓派4B 更新wiringPi库到2.52的方法

admin · 发表于 2020-7-21 15:30:47

最新发布的树莓派4B在烧录了官方系统buster以后，如果直接使用gpio readall去查看GPIO会出现错误。无法识别的情况，需要根据以下步骤进行wiringPi的更新：

登陆后打开一个终端输入：

cd /tmp
; T; s1 f" M. @) e: h4 m1 C9 s
wget https://project-downloads.drogon.net/wiringpi-latest.deb: d. }9 f3 f/ T- z: m7 z. o
sudo dpkg -i wiringpi-latest.deb

复制代码

然后再使用

gpio -v

复制代码

检查版本信息，确保版本为：2.52即可。

然后再执行：gpio readall
