自己做的，针对STC单片机，不断电下载程序，只需要把我写的程序加到你的代码前面，就可以通过 STC——ISP软件的不断电下载功能下载，实测很好用，下载程序再也不用不停的断电上电，免去很多麻烦。(Do it yourself, for STC microcontroller, power download program, only need to put in front of a program I wrote to your code, you can download the STC download through continuous electrical ISP software, measured very good, download the program will not stop the power-off, without very much trouble.)
