Raspberry Pi's latest kernels and firmware, including Raspbian and NOOBS releases, now by default use Device Tree (DT) to manage some resource allocation and module loading. This change is to alleviate the problem of multiple drivers contending for s…

ABSTRACT There are two main methods for building the kernel. You can build locally on a Raspberry Pi which will take a long time; or you can cross-compile, which is much quicker.There is an introduction about cross-compilation as follows. You need ub…

使用device-tree (DT) overlay应该是更方便的方法: http://blog.gegg.us/2017/01/setting-up-a-gpio-button-keyboard-on-a-raspberry-pi/ Back in late 2013, when I wrote the first Version of a raspberry-pi based software controlling a HD44780 based 4×20 characters LCD a…

there are some things to do for raspberry pi 3b for the first time: 1, connect pi with monitor/KB/mouse, then power on it and go into its desktop(by default):expand system up to the whole storage of SD card(it seems to be maximum of 64G by official e…

Raspberry Pi 手把手教你在树莓派上安装USB无线网卡支持WIFI 树莓派虽然已经有了有线网卡,但是并未配置无线网卡,移动性不够强,好在机器配备了2个USB口,当然要分一个出来给WIFI无线网卡使用了,这样小派使用起来就更便利了!我手头有个NetCore磊科NW336无线网卡,非常便宜的那种,好像芯片是Realtek的,插入USB口试试,发现网卡上的指示灯会闪烁,感觉有戏,马上登陆系统折腾:(一)查看USB设备类型,寻找USB无线网卡是否已经被系统识别.运行lsusbpi@raspbe…
