VHDL源码其中“music_rom”使用FPGA厂商提供的工具生成的,如Altera的Quartus II 及其宏功能生成的这些文件。 另外,我们还希望实现以下功能: * 播放音乐时,在ROM的结尾处暂停 * "fullnote"值为0时,表示静音 所以我们将原来的程序的最后一行从

T-kernel 的extension源代码,是日本最著名的T-kernel所独有的,适合开发T-kernel的朋友们使用! TK/SE is the program that extends T-Kernel and provides the functions such as a file system and a process management. The TK/SE archive to be provided is comprised of the main portion and the 2 extended file system portions, and TK/SE object is built by adding these to T-Kernel source. a) tkernel_se_1.00.00.tar.gz Main source of T-Kernel/SE b) extfs_fatfs_1.00.00.tar.gz Difference source of T-Kernel/SE extended file system (FAT) c) extfs_cdrom_1.00.00.tar.gz Difference source of T-Kernel/SE extended file system (CD-ROM)

用51单片机做的简单频率计,KEIL C环境,带工程文件,可直接编译运行.主要演示如何在内存很少,无法启用RTOS的单片机(例如2051)中使用状态机和时间片来完成实时多任务并行处理.例子中对键盘,信号采集和LED数码管的显示三部分进行了并行处理,而采用的单片机是仅有256字节内存2K ROM的89C2051.

Finally: a hands-on, Java-centric workbook companion for the classic Design Patterns! Workbook approach deepens your understanding, builds your confidence, and strengthens your skills. Covers all five categories of design pattern intent: interfaces, responsibility, construction, operations, and extensions. CD-ROM contains all code examples from the book -- plus bonus code examples not found in the book. About the Author: Steven John Metsker is a researcher and author focused on advanced techniques for magnifying the abilities of object-oriented software developers. A rising star in the patterns community, he was recently invited to join the acclaimed Hillside Group. He is author of Building Parsers with Java? (Addison-Wesley).

--功能描述 --1 刷卡后产生与本人身份唯一对应的串行二进制码元序列,作为模拟系统的输入信号(此处不妨设为8位学生学号)。 --2 经过串并转换,序列变成一个8位二进制数。 --3 遍历预先存储在rom中的学号信息,逐一和这个8位数相比较,如果有相匹配的信息,显示欢迎字样(此处用一个高电平表示),同时打开栅栏门(也用一个高电平表示)。
