C51活泼流水灯(C语言)

C51活泼流水灯(C语言) 实验要求] 单片机P1口相连的8个发光二极管中的一个循环移位点亮，同时蜂鸣器发出滴滴的响声。 蜂鸣器用一PNP三极管驱动，集电极（C极）通过蜂鸣器线圈接5V电源，基极（B极）是控制端，发射极（E极）接地，当三极管C，B极PN结正偏时，PN结导通，即B极为低电平时，三极管导通，蜂鸣器响。再不明白去看模电书。 [实验目的] 掌握循环移位的工作原理，学会使用封装好的函数库， 延时函数的时间估算。

OPA2357AIDGST.pdf

The OPA357 series of high-speed, voltage-feedback CMOS operational amplifiers are designed for video and other applications requiring wide bandwidth. They are unity-gain stable and can drive large output currents. Differential gain is 0.02% and differential phase is 0.09°. Quiescent current is only 4.9mA per channel.

K9F5608U0D-PCB0.pdf

Offered in 32Mx8bit , the K9F5608X0D is 256M bit with spare 8M bit capacity. The device is offered in 1.8V, 2.65V, 3.3V Vcc. Its NAND cell provides the most cost-effective solutIon for the solid state mass storage market. A program operation can be performed in typical 200µs on a 528-byte page and an erase operation can be performed in typical 2ms on a 16K-byte block. Data in the page can be read out at 50ns cycle time per byte. The I/O pins serve as the ports for address and data input/output as well as command input. The on-chip write control automates all program and erase functions including pulse repetition, where required, and internal verification and margining of data. Even the write-intensive systems can take advantage of the K9F5608X0D′s extended reliability of 100K program/erase cycles by providing ECC(Error Correcting Code) with real time mapping-out algorithm.

K4T1G164QE-HEC6.pdf

The 1Gb DDR2 SDRAM is organized as a 32Mbit x 4 I/Os x 8 banks, 16Mbit x 8 I/Os x 8banks or 8Mbit x 16 I/Os x 8 banks device. This synchronous device achieves high speed double- data-rate transfer rates of up to 667Mb/sec/pin (DDR2-667) for general applications.

Texas Instruments offers multiple highly optimized reference designs based on the TMS320DM3x DaVinci™ video processors for the IP camera market to enable developers to speed through the design process as well as reducing overall bill of materials costs. These reference designs:

DM9161.pdf

The DM9161B is a physical layer, single-chip, and low power transceiver for 100BASE-TX and 10BASE-T operations. On the media side, it provides a direct interface either to Unshielded Twisted Pair Category 5 Cable (UTP5) for 100BASE-TX Fast Ethernet, or UTP5/UTP3 Cable for 10BASE-T Ethernet. Through the Media Independent Interface (MII), the DM9161B connects to the Medium Access Control (MAC) layer, ensuring a high inter operability from different vendors.
