随着单片机技术的不断发展，IAP(In-Application-Programming)功能的支持越来越普遍，这给应用系统程序代码升级带来了极大的方便。但是，ISP(In-System-Programming)程序的设计以及程序空间的安排等，是需要开发者认真细致考虑的。本文针对STC新型单片机的应用ISP程序设计作了详细的介绍，以STC11F62X为例，详细说明了具体实现过程，并给出了Keil-C源代码-With the continuous development of SCM technology, IAP (In-Application-Programming) function support and more common, this upgrade to the application code has brought great convenience. However, ISP (In-System-Programming) program design and program space in the arrangements is the need for developers to carefully consider. This new microcontroller applications for STC ISP programming are introduced in detail to STC11F62X example, the detailed descr iption of the specific implementation process, and gives the Keil-C source code
