STC提供的isp烧写工具，不用安装直接使用，不是stc的单片机可能烧写不了，但是里面有常用的范例程序，还有定时器初值计算（可以根据不同的晶振频率，选择不同的定时方式，会算出定时精度以及显示相应的程序），个人感觉很实用，一起分享-STC isp programming tools provided, do not install directly, not stc SCM may not be burning, but there are examples of commonly used procedures, as well as timer initial calculations (according to different crystal frequency, choose a different timing modes will calculate the timing accuracy and display the corresponding program), personal feel very useful, share with
