AES在AVR单片机上的实现 资源要求 Program: 4492 bytes (6.9％ Full) (.text + .data + .bootloader) Data: 745 bytes (9.1％ Full) (.data + .bss + .noinit) 可以在AVR Studio中模拟运行 AES加密和解密 在AVR Studio 中模拟运行 Ctrl+F7 后，模拟执行到main入口处 按F5后, 知道到加密完成 可以看出加密的结果 再按 ...

对任意给定的文法G 构造LR(1) 项目集规范族，其中要实现CLOSURE(I)、GO(I,X)、FIRST 集合等。在此基础上， 构造了LR（1）分析表。然后对输入的句子进行语法分析，给出接受或出错报告。 程序采用文件输入输出方式。其中包括两个输入文件：文法grammar.txt，以及 输入串input.txt；两个输出文件：项目集items.txt 和文法的LR( ...

基于S3C2440的四线电阻式触摸屏驱动程序，linux2.6.22内核。把touchscreen.c放在driver/input/touchscreen/下。修改arch/arm/mach-s3c2440/mach-smdk2440.c以及相应的Makefile加上驱动即可。

This is the source for a C compiler that generates 386 or m68K code. Code generation is fairly good although the optimizer is a little naive... the code itself should be highly portable although there are some issues involved with porting from MSDOS that have to be resolved for example the size of L ...

Flash中内置了一个状态寄存器（Status Register，SR）来指示Flash的当前工作状态和各种操作是否成功。要读取SR的当前值需要向CUI发送读状态寄存器命令（Read Status Register），命令码为0x70，SR中的内容将在DQ[7:0]上输出。The Read Status Register （0x70）command causes subsequent reads to output data from the SR ...

This article introduces how to construct a Hospital Ward Information System with three-tiered technology. The System applies to UML, BDE, MIDAS, distributed compute theory and a special architecture to make such functions: patients check in and check out, prescription input, drug-delivery at center ...
