  • 基于单片机AT89C51的MP3播放系统的设计方案

    提出一种基于单片机AT89C51SND1C的MP3播放系统的设计方案。单片机集成了专用的解码器,使用K9F1208闪存作为外存储器,放音电路采用CS4330,存储文件通过播放器上的USB接口设备从PC机上直接下载,液晶显示采用LCD1602。方案设计简单,性价比高,低功耗,易扩展。由于采用的是通用单片机实现的,可以很容易地移植到其他微控制器系统中,有很强的市场竞争能力和实用价值。 Abstract:  A MP3 player design based on microchip AT89C51SND1C was presented, which used K9F1208 Flash chip as the memory circuit and used CS4330 as play chip. Storage files were download from PC through USB interfaces player on the deviCE,and the LCD/602 was used as display screen. This system had characteristics of simple design,low power,easy expand,low cost and high recognition. Using of universual microchip make it easy to transplant to other microcontrol system,and have strong market competitiom and practical value.

  • 基于双ATmega128的安检力学试验机设计

    针对当前安检力学试验机所能完成的试验种类单一、自动化程度低等问题,提出一种以ATmega128单片机为核心控制器的安检力学试验机的设计。详细阐述了该安检力学试验机各个组成部分的设计原理和方案,并且给出了各部分的软件设计思想和操作流程。经过大量测试试验表明:设计的安检力学试验机可以完成多达十余种的力学安检试验,完全符合相关国家标准,并且具有数据采集精度高、传输速度快、操作安全简便等特点,实现了安检设备的多功能化、数字化和自动化。 Abstract:  Currently, many mechanical security testing machines have only one function. The degree of automation of them is low. To solve those problems, a new kind of mechanical security testing machine, using ATmega128 micro-controller as its core controller, has been advanced. It describes the components of the machine. The principles and the scheme in the designing processes are presented in detail, and the software architecture and the operation processes of each part are given. After having done many testing, we have reached the following conclusions: the mechanical security testing machine presented can do over ten mechanical security tests complying with related national standards. It has high data acquisition accuracy and high transmission speed. The operation of the machine is simple and safe. In general, this machine is a multi-functional, highly automatic, digitalized security testing deviCE.

  • CAT93C46 器件数据手册

    The CAT93C46 is a 1 kb Serial EEPROM memory deviCE which isconfigured as either 64 registers of 16 bits (ORG pin at VCC) or 128registers of 8 bits (ORG pin at GND). Each register can be written (orread) serially by using the DI (or DO) pin. The CAT93C46 features aself−timed internal write with auto−clear. On−chip Power−On Resetcircuit protects the internal logic against powering up in the wrongstate.

  • SN65LBC170,SN75LBC170,pdf(TRIP

    The SN65LBC170 and SN75LBC170 aremonolithic integrated circuits designed forbidirectional data communication on multipointbus-transmission lines. Potential applicationsinclude serial or parallel data transmission, cabledperipheral buses with twin axial, ribbon, ortwisted-pair cabling. These deviCEs are suitablefor FAST-20 SCSI and can transmit or receivedata pulses as short as 25 ns, with skew lessthan 3 ns.These deviCEs combine three 3-state differentialline drivers and three differential input linereceivers, all of which operate from a single 5-Vpower supply.The driver differential outputs and the receiverdifferential inputs are connected internally to formthree differential input/output (I/O) bus ports thatare designed to offer minimum loading to the buswhenever the driver is disabled or VCC = 0. Theseports feature a wide common-mode voltage rangemaking the deviCE suitable for party-lineapplications over long cable runs.

  • 单片机通过CH375读写U盘时的注意事项

    USB总线接口芯片CH375支持USB-HOST和USB-deviCE,可以用于单片机读写U盘。本说明中的多数内容为建议性说明,而非强制性说明,建议的目的旨在提高最终产品的稳定性和可靠性,很多内容只是针对一般情况和大多数用户而言,而未考虑个别或者例外。本说明中列举了一些发生在某些品牌U盘上的怪现象,都是我们实际测试现象的描述,我们并没有以此评价U盘的优劣,因为实际上它们可能已经算是所有U盘中比较优秀的几种,而且,我们也不排除这仅仅是品牌U盘中的个别现象,只是正好被我们碰到而已。

  • FET430PIF自制资料

    The MSP-FET430PIF is a Parallel Port interface (does not include target board) that is used to program and debug MSP430 FET tools and test boards through the JTAG interface. This interface is included in our FET tools, but sold without the development board. This interface uses a Parallel PC Port to communicate to the Debugger Software (IAR Kickstart software included) running on the PC. The interface uses the standard 14 pin header to communicate to the MSP430 deviCE using the standard JTAG protocol. The flash memory can be erased and programmed in seconds with only a few keystrokes, and since the MSP430 flash is extremely low power, no external power supply is required. The tool has an integrated software environment and connects directly to the PC which greatly simplifies the set-up and use of the tool. The flash development tool supports development with all MSP430 flash parts. Features MSP430 debugging interface to connect a MSP430-Flash-deviCE to a Parallel port on a PC Supports JTAG debug protocol (NO support for Spy-Bi-Wire (2-wire JTAG) debug protocol, Spy-Bi-Wire (2-wire JTAG) is supported by MSP-FET430UIF) Parallel Port cable and a 14-conductor target cable Full documentation on CD ROM Integrated IAR Kickstart user interface which includes: Assembler Linker Limulator Source-level debugger Limited C-compiler Technical specifications: Backwardly compatable with existing FET tool boards.
