在teensy上保存批处理文件

本文关键字:批处理文件 保存 teensy | 更新日期: 2023-09-27 18:25:41

我有一个Teensy 3.2,我想在上面存储一个批处理文件。我发现,Teensy有一个2kb的EEPROM,我可以在那里存储它。

批处理文件正在生成一个.exe文件,其中包含已编译的C#。

但现在我有两个问题:

  1. 批处理文件太大(3.37kb),有没有办法缩小它
  2. 如果我想的话,我该如何在Teensy上传输该文件(如果它有合适的大小),然后再次将其重新传输到计算机上?我只能找到EEPROM.write()作为方法,但由于我想传输文件,而不仅仅是单个字节,这似乎对我不起作用

这是批次的代码:

// 2>nul||@goto :batch
/*

@echo off
setlocal
set "csc="
for /r "%SystemRoot%'Microsoft.NET'Framework'" %%# in ("*csc.exe") do  set "csc=%%#"
if not exist "%~n0.exe" (
   call %csc% /nologo /r:"Microsoft.VisualBasic.dll" /out:"%~n0.exe" "%~dpsfnx0" || (
      exit /b %errorlevel% 
   )
)
%~n0.exe %*
endlocal & exit /b %errorlevel%

编辑:现在代码已经足够小了(大约1.73kb),但我仍然不知道如何在Teensy上传输,请帮我

在teensy上保存批处理文件

最小化C#代码:

  1. 将所有变量设为一个字母
  2. 删除所有换行符,使代码在一行中
  3. 删除所有不必要的空格
  4. 替换常用单词(使用在线文本分析器)

    @echo off
    setlocal enableDelayedExpansion
    for /f "delims=" %%a in (source.txt) do set code=%%a
    for %%a in ("<:IntPtr " ">:public " "#:int " "&:GDI32." "':static " "`:User32" "@:extern " "':.dll" "$:DllImport(" "|1:Drawing." "|2:System" "|3:DeleteObject" "|4:private " "|5:using " "|6:ScreenCapture" "|7:SelectObject" "|8:CreateCompatible" "|9:GetWindowRect") do (
        for /f "delims=: tokens=1,2" %%b in ("%%~a") do set "code=!code:%%c=%%b!"
    )
    echo !code!>compressed.txt
    
  5. compressed.txt的内容作为批处理文件的最后一行

@echo off
if exist "%~n0.exe" goto run
setlocal enableDelayedExpansion
for /r "%SystemRoot%'Microsoft.NET'Framework'" %%a in ("*csc.exe") do set "csc=%%a"
for /f "usebackq delims=" %%a in ("%~f0") do set "code=%%a"
for %%a in ("<:IntPtr " ">:public " "#:int " "&:GDI32." "':static " "`:User32" "@:extern " "':.dll" "$:DllImport(" "|1:Drawing." "|2:System" "|3:DeleteObject" "|4:private " "|5:using " "|6:ScreenCapture" "|7:SelectObject" "|8:CreateCompatible" "|9:GetWindowRect") do (
    for /f "delims=: tokens=1,2" %%b in ("%%~a") do set "code=!code:%%b=%%c!"
)
echo !code!>"%temp%'tmp.c"
%csc% /nologo /r:"Microsoft.VisualBasic.dll" /out:"%~n0.exe" "%temp%'tmp.c"
if errorlevel 1 exit /b %errorlevel%

1874字节!

你可以通过替换更多的单词来使它变得更小。
