提出了一種以S3C2440A為核心處理器的銀行評價器的設計方案,并結合XILINX公司的XL95144XL型CPLD,輔助S3C2440A,實現該銀行評價器的各部分功能以及系統信號之間的相互協調。該評價器在系統設計上采用液晶屏顯示,代替了以往簡單的數碼管電路的顯示模式,在視覺上給人以全新的享受。同時,評價器增加了新的網絡供電方式,只要將評價器連接上網絡就可以正常工作,方便了客戶的使用??傊丝钽y行評價器采用了嵌入式系統的設計方案,大大豐富了系統功能,實現一個銀行評價器設計的新突破。
Abstract: S3C2440A of SamSung company is the core component of the embedded system. A design of bank assessor based on S3C2440A was provided in this paper. It used XL95144XL combined with S3C2440A to realize all the functions and coordination with system signals. This bank assessor used LCD to display instead of the former simple digital display and provided a new seusuous enjoment. Meanwhile,it provided a new method of network power supply,that the bank assessor could regularly work once it connected to the network,which is convenient for customers to use. In a word,this assessor takes embedded system,enriches the system’s functions and reclizes a new breakout.
針對眾多低成本數據采集需求,采用帶有片上USB控制器和D/A轉換器的混合信號微處理器C8051F340,設計了一款可通過USB接口和LabVIEW圖形用戶界面實現與PC機聯機的數據采集器,同時借助系統的SD卡存儲獨立實現現場長時間采集數據。該數據采集器成本低,結構簡單,體積小,已成功用于工業現場。
Abstract:
Aiming at the need of low cost data acquisition, a data acquisition device is designed based on C8051F340 which is a mixed-signal microcontroller and integrates USB controller and A/D controller on a chip.The data acquisition device which can combine with PC by USB interface and LabVIEW graphical user interface,can realize data acquisition. At the same time,it can be solely run a long time in virtue of SD card in field.The date aequisition device features low cost,simple structure and little sharp, and it has been used in industry field.
