命令行刷写 Leonardo

有些情况下,我们需要在命令行下刷写 Leonardo 的 Firmware,一般的方法会遇到问题,原因是 Leonardo 进入 Bootloader 的方式比较特别:使用 1200波特率打开串口,Leonardo立即开始重启,重启之后运行的Booloader会让串口变化成为另外的编号,在这个过程中如果有握手,那么就开始 Firmware 的更新。因为中间串口会发生变化,因此一般的刷新方法都会都会碰到问题。

最近,我在网上网上看到了一个高手编写的代码,能够在 Windows下实现全自动的命令行刷写https://github.com/p1ne/arduino-leonardo-uploader/tree/master/windows

核心是一个 BAT 批处理文件,首先用 WMI 在系统中查找包含 Leonardo 字样的串口,然后用 mode 来设置这个串口,这样 Leonardo 就会去Reset。接下来再使用 WMI 在系统中查找Leonardo Bootloader 的字样确定新出现的串口号。然后就用 avrdude 来进行正常刷写了。

具体代码如下,相信看懂并不困难:

rem @echo off
setlocal

for /f "tokens=1* delims==" %%I in ('wmic path win32_pnpentity get caption  /format:list ^| find "Arduino"') do (
    call :resetCOM "%%~J"
)

:continue

:: wmic /format:list strips trailing spaces (at least for path win32_pnpentity)
for /f "tokens=1* delims==" %%I in ('wmic path win32_pnpentity get caption  /format:list ^| find "Arduino Leonardo bootloader"') do (
    call :setCOM "%%~J"
)

:: end main batch
goto :EOF

:resetCOM <WMIC_output_line>
:: sets _COM#=line
setlocal
set "str=%~1"
set "num=%str:*(COM=%"
set "num=%num:)=%"
set port=COM%num%
echo %port%
mode %port%: BAUD=1200 parity=N data=8 stop=1
timeout /t 1
goto :continue

:setCOM <WMIC_output_line>
:: sets _COM#=line
setlocal
set "str=%~1"
set "num=%str:*(COM=%"
set "num=%num:)=%"
set port=COM%num%
echo %port%
goto :flash

:flash
avrdude -v -CD:\arduino-1.8.4\hardware\tools\avr\etc\avrdude.conf -patmega32u4 -cavr109 -P%port% -b57600 -D -V -Uflash:w:./blink.ino.hex:i

 

特别注意的是:
1. 如果你在 Win10 上使用并且没有安装 Leonardo 驱动的话,设备名称不会出来 Arduino 字样,安装2个驱动(一个是 Bootloader的,一个是 Arduino 本身的)之后即可正常工作;
2. 注意最后 avrdude.conf 的路径不要搞错了
3. 要刷写的文件也是在最后一条命令上,我这里使用的是blink.ino.hex:i

我这边实验的结果如下:
