原链接是 USB ISP 刷机, 但是 N76E003 并没有 USB 外设,所以改成了 串口下载,
Windows7 64bit Python3 测试通过,
写得不是很严谨, 有些地方还需要推敲。

问题解决方案
在这里找到了解决方案.
原因在于pyinstaller没有把一些外部的库包含进来,导致报错。一个可行的解决方案如下:
将.spec修改至如下所示(.spec文件会在第一次运行pyinstaller后出现):
binaries = [
('C:\\Windows\\System32\\libusb0.dll', '.'),
]a = Analysis(['myscript.py'],
...
binaries=binaries,
datas=[],
hiddenimports=['usb'],
...
我也觉得是缺 libusb0.dll

这个协议貌似有问题,发出去的数据没有校验。
64字节是为了兼容USB协议吧?

这个可以用 wheel 打包成 wheel 包更时候跨平台安装,此代码在 linux 下能运行吗?
