该程序设计采用2051进行控制,原理比较简单.但是要完全调试成功比较麻烦!我自己已经调试差不多了,祝大家都可以掌握基本控制理论!-procedures designed using the 2051 control, principle is relatively simple. However, to successfully complete debugging more trouble! I have been debugging almost wish you could grasp the basic control theory!

这是DSP2407的RAM测试程序,含全部源码,调试通过,可运行.-This is the DSP2407 the RAM test procedures, including all source code, debugging is passed, can be run.

之前看过论坛上有一个C8051和S3530A的通信程序，但我认为很复杂而不具有通用性，我自己写的一个3530通过I2C总线与单片机的通信程序,虽然很短,但是很实用.-Read before the forum have a C8051 and S3530A communications procedures, but I think very complex and not universal, and I wrote it myself a 3530 through the I2C bus communication with the SCM process, although very short, but very practical .
