我今天要來講個故事 ...

某天我在逛 的時候

開發硬體要求 • Arduino Leonardo Micro 200NT • micro USB
公對 USB 公 可以用 Android 傳輸線代替 50 NT ( 純粹裝 B 用 )
[email protected]
開發軟體要求 • Arduino IDE • 程式碼別寫太多, Leonardo 儲存空間比較小 建議不要用免安裝版,驅動可能會抓不到
[email protected]
OK ,回到正題
[email protected]
反正都叫 Arduino 有差嗎?
[email protected]
[email protected]
???
[email protected]
原因: 型號 控制器晶片 使用鍵盤 UNO MEGA328P Leonardo MEGA32U4
[email protected]
… … 可 可惡 結果還是要花 200 塊嗎 看到寫完的 code
不能跑 94 不甘心 換了開發板之後就能跑了, how 棒
[email protected]
能控制鍵盤之後,那就來嘗試看看丟檔案出來吧

DEMO 環境 Windows 7 Ubuntu 16.10 LTS vsftpd
[email protected]
安裝 vsftpd 與設定 $ sudo apt-get install vsftpd $
sudo apt-get install vsftpd $ sudo vim /etc/vsftpd.conf 找到 #write_enable=YES 按 insert 把 # 拿掉,然後按 ESC 輸入 :wq 存檔 $ sudo /etc/init.d/vsftpd restart

1. 一定要在英數模式,中文模式會 GG 2. 迴圈的 Delay 的時間一定要設長一點,不然調校的時候你 會崩潰 3.
絕對不要寫 shutdown 指令 BadUSB 地雷

來聊聊防禦方式
