此汇编程序实现A/D转换功能,应用于pic单片机上,A/D采用中断方式。该程序通过单片机的RA2模拟通道送入一直流电压,当送入的直流电压大于2.5V时,8个LED闪动,当直流电压恢复到2.5V以下时,LED停止闪动。为了防止干扰,本程序对直流电压采样10次后再作判断,中间的采样结 果用间接寻址的方式存取。

Recovering 3-D structure from motion in noisy 2-D images is a problem addressed by many vision system researchers. By consistently tracking feature points of interest across multiple images using a methodology first described by Lucas-Kanade, a 3-D shape of the scene can be reconstructed using these features points using the factorization method developed by Tomasi-Kanade.

SCSI Multimedia Commands 鈥?3 (MMC-3) T10/1363-D 5.16 READ CAPACITY Command The READ CAPACITY command (Table 144) provides a means for the Initiator to request information regarding the capacity of the Logical Unit. This command shall not report the correct capacity of the recorded data for CD-R, CD-RW and DVD-R/-RW media that does not have a Lead-out in the last Session or last Border-out. For CD-ROM, the returned logical block address is modified to allow returning a possibly inexact value (but one with a known error bound) based on the Table of Contents data

TLC548和TLC549是以8位开关电容逐次逼近A/D转换器为基础而构造的CMOS A/D转换器。它们设 计成能通过3态数据输出和模拟输入与微处理器或外围设备串行接口。TLC548和TLC549仅用输入/输出时 钟(I/O CLOCK) 和芯片选择(CS) 输入作数据控制。TLC548的最高I/O CLOCK输入频率为2.048MHz, 而TLC549的I/O CLOCK输入频率最高可达1.1MHz。 有关与大多数通用微处理器接口的详细资料已由工厂 准备好,可供使用。
