  • 基于FPGA的蓝牙HCIUART控制接口设计

    通用异步收发器UART(Universal Asynchronous Receiver/Transmitter)是广泛使用的串行传输协议。串行外设用到异步串行接口一般采用专用集成电路实现。但是这类芯片一般包含许多辅助模块,而时常不需要使用完整的UART的功能和辅助功能,或者当在FPGA上设计时,需要将UART功能集成到FPGA内部而不能使用芯片。蓝牙主机控制器接口则是实现主机设备与蓝牙模块之间互操作的控制部件。当在使用蓝牙设备的时候尤其是在监控场所,接口控制器在控制数据与计算机的传输上就起了至关重要的作用。 论文针对信息技术的发展和开发过程中的实际需要,设计了一个蓝牙HCI-UART(HOst Controller Interface-Universal Asynchronous Receiver/Transmitter)控制接口的模块。使用VHDL将其核心功能集成,既可以单独使用,也可集成到系统芯片中,并且整个设计紧凑、稳定且可靠,其用途广泛,具有一定的使用价值。 本设计采用TOP-DOWN设计方法,整体上分为UART接口和蓝牙主机控制器接口两部分。首先根据UART和蓝牙主机控制器接口的实现原理和设计指标要求进行系统设计,对系统划分模块以及各个模块的信号连接;然后进行模块设计,设计出每个模块的功能,并用VHDL语言编写代码来实现模块功能;再使用ISE8.2I自带的仿真器对各模块进行功能仿真和时序仿真;最后进行硬件验证,在Virtex-II开发板上对系统进行功能验证。实现了发送、接收和波特率发生等功能,验证了结果,表明设计正确,功能良好,符合设计要求。

  • Cadence Allegro 16.6破解Crack+高速下载+教程 Win7下可用

    最新Cadence Allegro 16.6破解版,Windows 7下32位和64位,经实际测试,顺利运行,请仔细阅读安装说明。 后面附有高速百度网盘下载链接,压缩包中包括破解文件及安装说明,下面 Cadence16.6的版本个人感觉值得更新,有很多更新真心很实用很强大,但最重要的Display net names的功能的加入实在是感激涕零啊,因为当初从AD转到Cadence16.3时最不习惯的就是PCB上木有NET显示啊... 小弟win7安装时破解方法如下: 具体的步骤: 1、安装licensemanager,问license时,单击cancel,然后finish. 2、接下来安装cadence的product,即第二项,直到结束. 3、在任务管理器中确认一下是否有这两个进程,有就结束掉,即cdsNameServer.exe和cdsMsgServer.exe,没有就算了.(电脑开机没运行过Cadence软件就不用执行这一步). 5、把破解文件夹crack中LicenseManager文件夹下的pubkey、pubkey.exe和lLicenseManagerPubkey.bat放到Cadence\\LicenseManager目录下并运行lLicenseManagerPubkey.bat (如果是WIN764位操作系统请把cdslmd.exe文件复制到Cadence\\LicenseManager目录下覆盖原文件。其他操作系统不用,直接下一步) 6、把破解文件夹crack里crack\\SPB_16.6\\tools的pubkey、pubkey.exe和Tools.bat放到Cadence\\SPB_16.6\\tools目录下并运行Tools.bat (注意看一下DOS窗口会不会一闪而过,如果运行差不多一分钟就说明破解成功) 7、打开破解文件夹crack里LicGen文件夹,然后双击licgen.bat生成新的license.lic,习惯上把这license文件拷到桌面上放着. 8.在电脑开始菜单中的程序里找到cadence文件夹,点开再点开License Manager,运行License servers configuration Unilily,弹出的对话框中点browes...指向第7步拷贝到桌面上的license.lic,打开 它(open)再点下一步(next),将HOst Name项中主机名改成你的电脑系统里的主机名(完整的计算机名称),然后点下一步按界面提示直到完成第7步. 9.在电脑开始菜单中的程序里找到cadence文件夹(windows7下),点开再点开,运行License client configuration Unility,填入5280@(你的主机名),点下一步(next),最后点finish,完成这第8步. 10.在电脑开始菜单中的程序里找到cadence文件夹(windows7下),点开再点开,运行Lm Tools,点Config Services项,Path to the license file项中,点Browes指向c:\\cadence\\License Manager\\license.dat(如果看不见icense.dat,请在类型中下拉选择DAT类型),打开它 (open)再点Save Service.然后启动一下服务。到此,破解完成. 11、如果以上步骤都完成了,打开软件提示找不到证书,请打开环境变量,用户变量中看看 CDS_LIC_FILE 变量值是否为 5280@(你的主机名),如果没 CDS_LIC_FILE变量名,请添加一个变量。变量名为CDS_LIC_FILE 变量值为 5280@(你的主机名) 12. 64位操作系统,软件破解完请把cdslmd.exe文件复制到Cadence\\LicenseManager目录下覆盖原文件。 附我用的破解文件,希望给win7安装不成功的有点帮助

  • 基于C8051F930的管道温度压力远程监测系统

       为解决输油管道温度压力参数实时监测的问题,设计了以C8051F930单片机作为控制核心的超低功耗输油管道温度压力远程监测系统。现场仪表使用高精度电桥采集数据,通过433 MHz短距离无线通信网络与远程终端RTU进行通信,RTU通过GPRS网络与PC上位机进行远程数据传输,在上位机中实现数据存储和图形化界面显示,从而实现输油管道温度压力参数的实时监测和异常报警。经实验证明,该系统的12位数据采集精度满足设计要求,漏码率小于1%,正常工作时间超过5个月,能实时有效地监测输油管道的温度压力参数,节省大量人工成本,有效预防管道参数异常造成的经济损失和环境污染。 Abstract:  In order to solve the problems on real-time monitoring of pipeline temperature and pressure parameters, the ultra-low power remote pipeline temperature and pressure monitoring system was designed by using the single chip processor C8051F930 as the control core. The high-precision electric bridge was used in field instruments for data collection, the 433MHz short-range wireless communication network was used to make communication between field instrument and RTU, the GPRS was used by the RTU to transmit data to the PC HOst computer, and the data was stored and displayed in the PC HOst computer, so the real-time monitoring and exception alerts of pipeline temperature and pressure parameters were achieved. The experiment proves that the system of which error rate is less than 1% over five months working with the 12-bit data acquisition accuracy can effectively monitor the pipeline temperature and pressure parameters in real time, it saves a lot of labor costs and effectively prevents environmental pollution and economic losses caused by abnormal channel parameters.
