我拥有一个 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,我可以在其中存储它。
批处理文件正在生成一个.exe
包含已编译 C# 的文件。
但是现在我有两个问题:
- 批处理文件太大(3.37kb),有什么办法可以让它更小?
- 如果我愿意,我如何能够在 Teensy 上传输该文件(如果它具有适当的大小),然后再将其重新传输到计算机?我只能找到
EEPROM.write()
作为方法,但是因为我想传输文件,而不仅仅是单个字节,这似乎对我不起作用?
这是批处理的代码:
// 2>nul||@goto :batch
/*
: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:现在代码足够小(大约 1.73kb),但我仍然不知道如何在 Teensy 上传输它,请帮帮我。
