this document is very important for vhdl code

本文介绍了一种控制普通阀门的阀门控制器的设计方案，该阀门控制器带有工业现场总线PROFIBUS－DP 的接口，可以实现阀门的远程控制和网络控制。本文主要的着力点为介绍利用PROFIBUS－DP 专用芯片SPC3 开发PROFIBUS－DP 设备中需要注意的一些问题，包括硬件接口设计，有关PROFIBUS－DP 规范标准的一些设计要点，以及利用PROFIBUS－DP 诊断功能的方法。本文对设计其它Profibus DP从站节点有很好的参考价值!-This paper presents a general valve control valve controller design program The valve controller with industrial PROFIBUS-DP interface. The valve can be achieved remote control and network control. This paper mainly focus on the use of PROFIBUS-DP SPC3 ASIC development PROFIB U.S.-DP equipment necessary to pay attention to a number of issues, including the hardware interface design, The PROFIBUS-DP standards in a number of design features, and the use PROFIBUS-DP diagnostic function method. In this paper, the design of other Profibus DP slave nodes are of value!

利用 OPB 定制外设连接 LCD 和 MicroBlaze 处理器-Custom OPB peripheral connectivity using LCD and MicroBlaze processors

interfacing 4x4 keypad with lcd. Simple code.

独立键盘的原理和设计和方法，里面附有C的源代码-Independent keyboard theory and design and methodology, which with C source code

有关DSP芯片告诉数据采集和信号处理方面的DSP芯片开发，很不错的DSP方面的参考资料-told the DSP data acquisition and signal processing DSP chip development, quite the DSP reference

主要给出msp430的程序代码，当然这只是嘴基本点程序集，具体程序代码还需要进一步涉及〉-MSP430 main program code is given, of course, this is only the basic point of the mouth assembly, the specific program code also needs to be further involved in

Multitasking on AVR microcontrollers

数据采集系统的好参考资料,高精度的传感器采集系统-Data acquisition system a good reference, high-precision sensor acquisition system
