二、开发环境搭建(Python + pySerial + wxPython + wxFormBuilder)
pzh-py-com工具是一个完全基于Python语言开发的应用软件,首先安装好Python 2.7.14,痞子衡的安装目录为C:\tools_mcu\Python27,安装完成后确保系统环境变量里包括该路径(C:\tools_mcu\Python27),因为该路径下包含python.exe,后续python命令需调用这个python.exe完成的。
在C:\tools_mcu\Python27\Scripts目录下默认有easy_install.exe,这是PEAK(Python Enterprise Application Kit)开发的setuptools包里的工具,这个工具可以用来完成安装python第三方模块的工作。我们需要借助easy_install.exe来安装pip工具:
PS C:\tools_mcu\Python27\Scripts> .\easy_install.exe pip
Searching for pip Best match: pip 9.0.1 Adding pip 9.0.1 to easy-install.pth file Installing pip-script.py script to c:\tools_mcu\python27\Scripts Installing pip.exe script to c:\tools_mcu\python27\Scripts Installing pip3.5-script.py script to c:\tools_mcu\python27\Scripts Installing pip3.5.exe script to c:\tools_mcu\python27\Scripts Installing pip3-script.py script to c:\tools_mcu\python27\Scripts Installing pip3.exe script to c:\tools_mcu\python27\Scripts Using c:\tools_mcu\python27\lib\site-packages Processing dependencies for pip Finished processing dependencies for pipPS C:\tools_mcu\Python27\Scripts> python -m pip install --upgrade pip

pip是Python的包管理工具,提供了对Python包的查找、下载、安装、卸载的功能。安装好pip工具之后,可以看到C:\tools_mcu\Python27\Scripts目录下多了pip.exe,为方便后续使用pip来安装其他Python包,确保系统环境变量里包括pip路径(C:\tools_mcu\Python27\Scripts)。我们可以借助pip来安装pySerial和wxPython包:
PS C:\tools_mcu\Python27\Scripts> .\pip.exe install pyserial
Collecting pyserial Downloading https://files.pythonhosted.org/packages/0d/e4/2a744dd9e3be04a0c0907414e2a01a7c88bb3915cbe3c8cc06e209f59c30/pyserial-3.4-py2.py3-none-any.whl (193kB) Installing collected packages: pyserial Successfully installed pyserial-3.4PS C:\tools_mcu\Python27\Scripts> .\pip.exe install wxPython

有了pySerial便可以访问Serial Port,有了wxPython便可以设计GUI。
单纯使用wxPython设计pzh-py-com GUI界面时仅能是手工写代码布局,手工布局的界面创建和修改起来都比较繁琐,我们需要一款可视化的界面设计工具,痞子衡选择的是wxFormBuilder,从其github官网下载安装包并安装到C:\tools_mcu\wxFormBuilder目录下。安装完成打开软件便可在Designer里尽情创作界面,创作完成后点击"Python"便可看到Python GUI源代码,这个GUI源代码后续直接复制到JaysPyCOM工程里使用。
至此pzh-py-com工具开发的Python基础环境便搭好了。
三、测试环境搭建(PyCharm + vspd + sscom)
在开发pzh-py-com工具过程中免不了要调试Python代码,所以我们还需要一个Python IDE,痞子衡选择的是PyCharm,在jetbrains官网下载PyCharm community免费版并安装,安装完成后打开PyCharm并创建名为pzh-py-com空工程,成功创建后会看到pzh-py-com目录下自动生成一个.idea的文件夹,该文件夹是用于pycharm管理项目。
有了PyCharm环境,便可以开始写pzh-py-com代码,代码在开发过程中,需要结合Serial Port进行联合调试,如果手里没有硬件串口设备,可以使用虚拟串口设备,vspd便是著名的虚拟串口驱动,从eltima官网下载vspd标准版并安装,安装完成后打开vspd可看到如下界面,COM10和COM11(COM号是自定义的)便是虚拟出来的串口设备号,并且已经完成了对接。
虚拟Serial Port设备已经有了并且对接了,最后还需要一个成熟的串口调试助手,作为串口通讯的另一方,痞子衡选取的是非常经典的sscom,从大虾官网下载sscom包,sscom是个免安装的工具,可以直接打开使用,设置sscom使用COM11,将来pzh-py-com使用COM10。
四、发布环境搭建(PyInstaller)
pzh-py-com工具开发和调试工作都完成之后,我们希望将她打包成一个独立的可执行文件(即运行设备不需要安装Python+pySerial+wxPython),PyInstaller可以帮助我们完成打包工作,所以我们需要利用pip工具安装PyInstaller包:
PS C:\tools_mcu\Python27\Scripts> .\pip.exe install pyinstaller

PyInstaller包安装好之后,环境搭建便大功告成
