Raspberry, bottom, and camera, top.Raspberry, bottom, and camera, top.Raspberry, bottom, and camera, top.Raspberry, bottom, and camera, top.底部是覆盆子，頂部是相機。 https://en.wikipedia.org/wiki/Raspberry_Pi是一台 35 美元的電腦；相機另加 25 美元。 新增電源和網路連接，即可遠端存取。 JMP 如何存取它？
在這個例子中，普林克（的一部分油灰suite）和 RunProgram（JMP 的一部分），將 JMP 連接到 Raspberry Pi 中的 Linux 命令列介面。 JMP 發送拉斯皮斯蒂爾命令，其參數告訴 Raspberry Pi 如何拍攝照片以及將其放置在何處，然後 JMP 關閉連接並從網路上的位置顯示圖片。
看https://community.jmp.com/t5/Uncharted/Can-JSL-talk-to-Linux/ba-p/33689使用非 Raspberry Linux 機器的類似想法。 問題之一是透過創建公鑰/私鑰對來避免密碼提示；我使用 puttygen（PuTTY 套件）來製作我的公鑰/私鑰對（未顯示），並且透過在 putty 中保存一個名為的配置文件，使我的 JSL 變得更加簡單相機;設定檔具有連接資訊：
PuTTY dialog high lighting load/save sessions and AuthPuTTY dialog high lighting load/save sessions and AuthPuTTY dialog high lighting load/save sessions and AuthPuTTY dialog high lighting load/save sessions and AuthPuTTY 對話框高照明負載/保存會話和身份驗證
PuTTY dialog showing private key in AuthPuTTY dialog showing private key in AuthPuTTY dialog showing private key in AuthPuTTY dialog showing private key in AuthPuTTY 對話方塊在 Auth 中顯示私鑰
Login using the public/private keyLogin using the public/private keyLogin using the public/private keyLogin using the public/private key使用公鑰/私鑰登錄
現在該設定檔也可用於普林克作為相機。 因此，這裡有一些用於登入的 JSL：
rp = RunProgram(
executable( "plink" ), // plink is part of the PuTTY toolset, a bit like SSH
options( "camerapi" ), // this is a saved session in PuTTY
ReadFunction(
Function( {this},
While( this << canread,
Write( this << read ); // stream output to JMP log window
Wait( .01 );
)
)
)
);此 JSL 離開RP持有一個在背景運行的 RunProgram 對象，等待 Raspberry 上的 shell 程式產生一些輸出...它將其複製到 JMP 日誌視窗：
The first yellow is a message from JMP; the last yellow is a prompt from the RaspberryThe first yellow is a message from JMP; the last yellow is a prompt from the RaspberryThe first yellow is a message from JMP; the last yellow is a prompt from the RaspberryThe first yellow is a message from JMP; the last yellow is a prompt from the Raspberry第一個黃色是來自 JMP 的訊息；最後一個黃色是樹莓派的提示
白色日誌視窗包含與黑色外殼視窗相同的登入結果。 ESC 的東西會對輸出進行顏色編碼，所以我得到青色提示。 RunProgram 物件仍在等待將一些指令傳遞給 Raspberry Pi。 構造一個命令並發送它：
// filename builds a path known to the linux (raspberry pi) computer; it is
// actually a nfs mount from yet another computer. This filename is where the
// picture will be stored. The windows computer running JMP can access the
// NFS mount via the H: drive, which is being supplied through VirtualBox.
filename = "capture/picNoOptions.jpg";
// raspistill is a raspberry pi-specific linux command to take a picture
// using the camera attached to the raspberry pi. Because this is a
// command line interface the command must end with a newline, as if
// it was typed at the keyboard and ENTER was pressed.
command = "raspistill --timeout 1000 --nopreview --output " ||"/mnt/nfsc/upscale/"|| filename;
rp << Write( command || "\!n" ); // send the raspistill command, via the linux command line
這會在日誌視窗中產生更多輸出：
The command is in yellow, it runs silently, and prompts for another commandThe command is in yellow, it runs silently, and prompts for another commandThe command is in yellow, it runs silently, and prompts for another commandThe command is in yellow, it runs silently, and prompts for another command該命令呈黃色，靜默運行，並提示輸入另一個命令
此時可關閉RunProgram連線；向正在運行的 shell 發送 exit 命令是徹底斷開連線的最佳方法：
// for RunProgram to end cleanly, the shell it is running must terminate
rp << Write( "exit\!n" ); // end the Linux shell session
同樣，有一些日誌視窗輸出：
The shell is now closedThe shell is now closedThe shell is now closedThe shell is now closed外殼現已關閉
JSL 的其餘部分將根據需要等待，然後進行清理：
// every thing above happened very quickly, but the raspistill and exit
// commands have not finished yet. ask the rp object, over and over, if
// the pipe of data from the shell back to JSL has been closed yet. Until
// the ReadEOF happens, RunProgram will not terminate nicely.
While( !(rp << isReadEOF), write("."); Wait( .25 ) ); // wait patiently while shell output goes to log
If( !(rp << canread) & !(rp << canwrite) & rp << isReadEOF,
rp = 0; // this will really make RunProgram go away
Write( "\!nDone" );
,
// possibly need to restart JMP, and possibly need to restart raspberry
Write( "\!nFailed to release rp" )
);因為我已經在等待輸出，所以它只是說“完成”。 您可能需要在之前新增 wait(0.1) if( 可以讀/可以寫/isReadEOF )每次都測試完成。

這款相機非常基本，最大解析度為 2592x1944（我認為這是原始的 5M 相機，還有 8M 版本），但確實允許控制曝光時間和類比增益，並且可以從感測器檢索原始像素。
