不知為什麼, 有時候要 Download Firmware to LPC2103 時會出現
下列錯誤訊息:

No Algorithm found for: 00000000H - 00001FC3H
Programming skipped!

後來發現要檢查 Options for Target -> Utilities -> Setting 設定:
1. RAM for Algorithm: Star: 0x40000000, Size: 0x0800
2. Programming Algorithm: LPC2000 IAP2 32KB Flash

How to Outputs PDF File from Gnuplot

發佈日期: 作者:
回覆

之前都是直接在 視窗輸出 之後再手動 列印成 PDF File
其實也可以直接輸出 PDF File:

gnuplot> set term pdf (will produce PDF output)
gnuplot> set output "printme.pdf" (output to any filename you use)
gnuplot> replot (recreates plot but you don't see it, goes to file)

搞定收工。

OpenSuSE 11.1 上的 TCL Library

發佈日期: 作者:
回覆

閒閒沒事
把之前在 Mac OS 上 跑的 NAND Flash Static Wear Leveling 的 EV程式
拿到 SuSE 上跑，結果居然 Compile 不起來
發現是 “-ltcl” 無法 link 到 正確的 TCL Library
若將之改為 “-ltcl8.5” 就 OK
嗯
好像是 TCL Library 在 Install 時有問題
自己動手修正：

$ (cd /usr/lib; sudo ln -s libtcl8.5.o libtcl.o)
$ (cd /usr/lib64; sudo ln -s libtcl8.5.o libtcl.o)

這樣 “-ltcl” 就 OK 了。

Display Localized Directory Name on Mac OS X

發佈日期: 作者:
回覆

如果你想建立一個目錄
並希望目錄名稱可以隨著『不同的系統語言設定』而『顯示不同的名稱』
範例：目錄 Work，在中文環境下顯示『工作』
步驟如下
1. change directory “Work” to “Work.localized”
2. create a diectory ./Work.localized/.localized
3. create a file ./Work.localized/.localized/en.strings

"Work" = "Work";

4. create a file ./Work.localized/.localized/zh_TW.strings

"Work" = "工作";

自動影片分割

因為要上傳影片到 Youtube
必須將影片分割成數個不超過10分鐘長度的小片段
可是在 Mac OS X 下好像沒有好用的軟體
可又不想用 Quicktime 來一個一個手動分割
所以參考了一些資料後
寫了一個 AppleScript
File name : splite.scpt

(*
    Splite Quicktime Movie into equally sized for Youtube
    YF Chen
    yfc@yfchen.com
*)

    set sourceFile to choose file with prompt "choose video file as source"
    set theFolder to (choose folder with prompt "Choose a folder for the slices:") as text

    tell application "Finder"
        my splitteVideo(sourceFile, theFolder)
    end tell

    on splitteVideo(sourceFile, theFolder)
    
    tell application "QuickTime Player 7"
        activate
        try
            open sourceFile
            on error
            display dialog "Open a movie first" buttons ["OK"] with title "Error"
            return
        end try

        -- get active movie
        set sourceDoc to document 1
        set theDuration to duration of sourceDoc
        set theTitle to name of sourceDoc
        set DurOverlap to 2 -- 2sec overlaping
        set DurScal to (90 * 1000)

        -- calculate segments
        set DurCut to (9 * 60) -- 9 min
        set DurDoc to (duration of sourceDoc) / DurScal
        set NumOfSeg to DurDoc div DurCut

        -- loop each segment
        repeat with i from 0 to NumOfSeg
            -- set segment selection
            set durStart to (i * DurCut) * DurScal
            set durEnd to ((i + 1) * DurCut + DurOverlap) * DurScal
            if durEnd > theDuration then
                set durEnd to theDuration
            end if
            set selection start of sourceDoc to durStart
            set selection end of sourceDoc to durEnd
            -- copy selection into new movie
            copy sourceDoc
            set newdoc to make new document
            paste newdoc
            set theSlice to i as integer as string
            set theFile to (theTitle & "_" & theSlice) & ".mov" as string
            set theFile_full to (theFolder & theFile) as string
            try
                save self contained newdoc in theFile_full
            end try
            close document theFile
        end repeat

        close sourceDoc
        quit

    end tell

end splitteVideo
