疫情防控常態化的今天,像我一樣的應屆畢業生大多面臨著“畢業即失業”的壓力,但咱們也不能因此停止學習。這不,為了提高自己的敲代碼能力,突發奇想能不能遠程敲代碼做實驗?
說干就干,經過一番折騰,終于實作了用樹莓派遠程開發51單片機。
專案原件清單
1.用來遠程連接的樹莓派3B(已經吃灰很久了….)
2.執行程式的51開發板;
3.顯示影像的攝像頭(翻出了一個10年前的老USB攝像頭…)
4.內網穿透工具花生殼;
5.一些繼電器(是不是猜不到這個是干嘛的,先保密)
專案流程
雖然樹莓派可以通過vnc進行遠程桌面,但喜歡折騰的我怎么能甘心必須安裝客戶端呢?這絕對不行!!!所以我選擇了帶有html5決議vnc協議的novnc,遠程部分ok。
51單片機的編譯軟體我選擇的是sdcc進行編譯,編譯后會出現hex檔案,但對于很多朋友來說這還不夠,hex格式的檔案還是很大,我們要用bin!!!大家可以使用Hex2bin來進行轉換,okok現在就剩下串口下載了,我們來解決遠程下載,這里我選擇的是開源的stcgal進行燒寫。
最后我們再來看看遠程攝像頭,遠程攝像頭的方案就有很多了,這里我選擇的是motion。
分析完了就讓我們擼起袖子加油干吧!
1. 燒錄完成系統后,老規矩來給樹莓派更換國內源;
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
sudo cp /etc/apt/sources.list.d/raspi.list /etc/apt/sources.list.d/raspi.list.bak
修改軟體更新源,執行如下命令:
sudo vi /etc/apt/sources.list
按i進入編輯模式,改成清華的軟體源地址,按ESC退出,然后 :x 回車保存退出。
deb http://mirror.tuna.tsinghua.edu.cn/raspbian/raspbian/ buster main contrib non-free rpi
deb-src http://mirror.tuna.tsinghua.edu.cn/raspbian/raspbian/ buster main contrib non-free rpi
修改系統更新源,執行如下命令:
sudo vi /etc/apt/sources.list.d/raspi.list
將原鏡像用#號注釋掉,然后插入清華的系統源地址,保存退出:
deb http://mirror.tuna.tsinghua.edu.cn/raspberrypi/ buster main ui
同步更新源及更新軟體包,執行如下命令:
sudo apt-get update
sudo apt-get upgrade
2. 更換完成源以后,開啟樹莓派自帶的開啟VNC
在終端輸入以下命令進入配置界面。
sudo raspi-config
依次操作:Interfacing Options -> VNC -> Yes。之后系統會提示你是否要安裝 VNC 服務,輸入 y 之后回車,等待系統自動下載安裝完成,如果祖師爺還是愛我們的話應該已經開啟成功了。
穩妥起見我們還是來查看本地是否安裝了vncserver(其實就是看看上面祖師爺有沒有顯靈)
whereis vncserver
如果沒有請手動安裝
yum install -y tigervnc-server
如果按照成功了就看這里哦
使用下面的命令來運行vnc
vncserver
此時會要求輸入密碼。這里需要注意:
The VNC server will run in the background. The port that it runs on is the display number + 5900 (i.e. 5901 in the case above).
意思就是當你執行vncserver :1設定為1時,下面要運行VNC是的埠號應該是5900+1,那就是5901,VNC的默認埠是5900。
3. 安裝novnc
#安裝git
sudo apt-get install git
#獲取novnc的原始碼
git clone https://github.com/kanaka/noVNC
進入novnc的目錄
cd noVNC
運行novnc(第一次運行的時候會下載一個埠轉發的程式可能需要一些時間)
./utils/launch.sh --vnc localhost:5901
4. 安裝51開發環境
這里的開發環境依賴python3,需要確保已安裝python3, pip3.
如果沒有下載pip3請下載安裝
安裝sdcc
sudo apt-get install sdcc
編譯程式例子:
sdcc 1.c
安裝hex2bin(如果是不是專業開發者感覺可以不安裝)
百度網盤分享地址:
鏈接:https://pan.baidu.com/s/1iky8HsB-nVn1p5J3EzB8NQ
提取碼:tg3v
安裝pyserial
sudo pip3 install pyserial
安裝stcgal
pip3 install stcgal
測驗
stcgal -h
#下載程式樣例(建議完成安裝ch340后在進行下載測驗)
stcgal 1.ihx
5. 樹莓派安裝CH340驅動
驅動下載官方網址(linux版本)
http://www.wch.cn/download/CH341SER_LINUX_ZIP.html
cd 進入檔案夾
安裝依賴環境
sudo apt-get install linux-headers
修改make檔案
打開ch34x.c原始碼,添加#include <linux/sched/signal.h>,并注釋掉waitqueuet wait
編譯并加載驅動
make
make load
6. 安裝usb攝像頭監控界面
sudo apt-get install motion
然后打開 motion daemon 守護行程,讓他可以一直在后臺運行:
sudo nano /etc/default/motion
#no修改成yes:
start_motion_daemon=yes
修改motion的組態檔:
sudo vim /etc/motion/motion.conf
#deamon off 改成 on
deamon on
#設定解析度
width 800
height 600
#關閉 localhost 的限制
webcam_localhost off
然后運行 motion:
sudo motion
現在我們的攝像頭已經變成了一臺網路攝像頭。在chrome瀏覽器下訪問 http://[your.domain]:8081 即可看到攝像頭當前拍攝的畫面。
7. 簡單修改novnc界面
在onvnc原始碼的app目錄下面添加camera檔案夾
這里是jq的一個小插件實作了一個可以拖動的小框框

提取碼:swk9
最后修改vnc.html檔案讓我們把攝像頭和遠程界面合二為一
