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。

新唐的ISP协议还算比较简单,

一问一答形式, 上位机，下位机每次通讯都是64字节.

其中上位机发出:

第0字节 ---- 命令
第4-7字节 ---- 包序号，小端格式, 32bit整数

下位机回应:
第0字节 ---- 收到64字节的命令和
第4-7字节 ---- 收到的包序号+1

Gentlepig 说：

在win下复制了21论坛的代码并运行，报错，无法导入usb.core模块，然后用pip安装了pyusb，import usb.core这一步不报错了。但self.dev = usb.core.find(idVendor=0x0416, idProduct=0x3F00)这一行出现了异常：
usb.core.nobackenderror。

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

话说我最近研究了以下。前次提到的那个下载器已经可以在keil里面直接一键下载了

厉害厉害, 可以分享固件吗?
