前言 上一篇我们讲了在linux环境下给树莓派安装系统及入门各种资料 ,今天我们更进一步,尝试在PI3上安装openCV开发环境. 博主在做的过程中主要参考一个国外小哥的文章(见最后链接1),不过其教程中有一个地方稍微有点问题,导致我入坑好久!这里也会着重说明下. 1.Expand filesystem 新安装系统之后,首要的工作就是扩大文件系统.因为,用SD卡安装完系统后一大部分空间实际是未被分配的: sudo raspi-config 选择7高级,然后选择“1. Expand File Sy…

使用htpdate同步时间 由于树莓派板子上没有 RTC 硬件和电池,因此树莓派上的系统时间重启是保存不了的.网上已经有人想到应对 NTP 被防火墙封掉类似的需求了,开源的 htpdate 命令直接使用 HTTP 协议来进行系统时间同步,项目主页在这里: https://github.com/iridium77/htpdate htpdate 的原理也非常简单,直接解析 HTTP 协议头中的服务器时间信息,然后设置本地时间,我们来看百度返回的 HTTP 头: HTTP/1.1 200 OK Da…

最近公司有项目想要在树莓派上做,代替原来的工控机(我们是把工控主机当作小的主机用,一台小的工控主机最少也要600左右,而树莓派只要200多).于是,公司买了一个Raspberry Pi B+和一个Raspberry Pi 2 B,并要求能在B+上做就尽量用B+,原因很简单,B+比Raspberry Pi 2要便宜70左右.拿到闻名已久的树莓派之后很是兴奋,试着从官网下载了官方推荐的镜像raspbian,用Win32DiskImager烧录到SD卡上,然后上电,起初屏幕上什么都没显示,不管重新烧写…

最新的下载地址是: https://www.offensive-security.com/kali-linux-arm-images/ 按照官网的说法是找不到树莓派版本的SHA1SUM和SHA1SUMS.gpg文件的,所以官网上以下的验证没法继续做:…

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…

本文主要用于记录安装过程,以便日后查阅回顾. 之前在自己的树莓派上运行的一直是通过NOOB安装的Raspbian,但是本人平时更喜欢用Fedora作为开发和使用环境,而且Raspbian上的软件包通常更新比较缓慢.因为树莓派2代B型上市前,树莓派的芯片都是armv6或者更早的架构,只能运行ARM架构的Raspbian或者Fedora 18及更早版本.树莓派2代B型搭载的芯片架构是armv7,树莓派3代搭载的芯片架构是armv8,这两种芯片都能够运行ARM架构的Fedora 23,而仅运行Rasp…

在树莓派上玩了一小段时间了,因为装的软件包越来越多,所以越来越感觉16G的SD卡没办法长期使用下去.于是采购了几张64G的SD卡,打算周末装上系统.可是按照一般的流程,在Windows下用SD Formatter格式化后,我的Raspberry Pi 2B似乎完全无动于衷,一点反应也没有.经过查找资料,找到了原因.主要是因为大于32GB的SD卡, SD Formatter会默认以exFAT的格式进行格式化,而Raspberry Pi目前的机型都还不支持对该格式的识别,因此才会无法识别大于32GB…
