dsp实现无限冲激响应滤波器(IIR)算法，低通巴特沃斯滤波器在其通带边缘1kHz 处的增益为-3dB，12kHz 处的阻带衰减为30dB，采样频率25kHz(dsp Infinite Impulse Response Filter (IIR) algorithm, low-pass Butterworth filter gain in its passband edge at 1kHz-3dB 12kHz at the stop-band attenuation of 30dB, the sampling frequency of 25kHz)

1．EMIF 接口 TMS320F28335DSP 的扩展存储器接口(EMIF)用来与大多数外围设备进行连接，典型应用 如 连接片外扩展存储器等。这一接口提供地址连线、数据连线和一组控制线。ICETEK–F28335-A 将这些扩展线引到了板上的扩展插座上供扩展使用。 2．液晶显示模块的访问、控制是由28335ADSP 对扩展接口的操作完成。 控制口的寻址：命令控制接口的地址为 0x208001，数据控制接口的地址为0x208003 和 0x208004，辅助控制接口的地址为0x208002。 3．显示控制方法： -液晶显示模块中有两片显示缓冲存储器，分别对应屏幕显示的象素，向其中写入数值将改 变显示，写入“1”则显示一点，写入“0”则不显示。(The 1.EMIF interface Extended TMS320F28335DSP memory interface (EMIF) is used to connect with the most peripheral equipment, typical application Such as The connecting piece of extended memory. This interface provides the address lines, data lines and a set of control line. ICETEK- F28335-A The extension line to the extension socket for plate on the expansion of the use of. 2 liquid crystal display module access, control by the 28335ADSP to the extended interface operation is complete. Addressing control port: Command and control interface address 0x208001, the address data control interface for 0x208003 and 0x208004, auxiliary control interface address for 0x208002. 3 display control method: - liquid crystal display module with two display buffer memory, respectively corresponding screen pixel, writing values will be changed to the Change display, write "1" shows a little, write "0" are not displayed.)

.NET环境下水晶报表使用总结 水晶报表是一个优秀的报表开发工具，本人在开发通用管理系统的时候，所有报表都使用水晶报表，其简单、易用和强大的功能令笔者倍加喜爱，现将水晶报表使用手记呈现给大家。 一、在使用自带的水晶报表时，请注册，否则只能使用30次 (. NET environment using Crystal Reports Crystal Reports is an excellent summary of the report development tools, I am in the development of common management system, all reports use Crystal Reports, its simple, easy to use and powerful features make doubly favorite author, now Crystal Reports presented to you using the Notes. First, when using the built-in Crystal Reports, please register, or can only use 30 times)
