51单片机系统中运用电脑上的大键盘
- 51单片机系统中运用电脑上的大键盘！ Keyboard接线 PS/2--------51 1 DATA------P3.4 3 GND 4 VCC 5 CLK-------P3.3 接在51的外部中断，触发方式为低电平 AT89x51使用12M Modified by Shen Peng! Postgraduate of 2003, 7 Department Harbin Engineering University-51 microcomputer system on the use of t
jianpan_vhdl
- 用VHDL实现的键盘扫描程序 可以稍微修改就可使用-using VHDL keyboard scanning procedure can be slightly modified to use
SPI_TEST
- This version of the code is compatible only with the AT89C2051 due to the location of the data buffer and stack in RAM. The code may be modified to work with the AT89C1051 by relocating or resizing the buffer and stack to fit into the small
alu64_struct
- 六十四位ALU设计源代码，可实现加减，逻辑与，或等多种功能。-64 ALU design source code can be modified to achieve, and logic, or other functions.
mmuos
- 这是一个不到2000行的操作系统，巧妙地利用ARM9 CPU的内存管理单元(MMU)实现进程的切换。ARM9的4G虚拟地址可分成128个进程空间，每个32M。虽然它们的虚拟地址(VA)都是0-(32M-1)，但是对应的MVA(Modified vitual address,由虚拟地址VA和进程号PID组合而来)不一样，设置MVA对应的页表指向不同物理地址就可以很方便地让各进程运行空间相互隔开。代码很少，注释丰富，希望能对想理解操作系统、了解ARM体系结构的朋友有所帮助。 -This is a
NORFLASH
- spansion公司的NorFlash:s29al004d的驱动代码。16位读取方式。在东芝32位CPU：TMP92ca25上调试通过。NorFlash的驱动方式基本上相同，其它品牌的NorFlash只需略微修改程序即可。-the NorFlash : s29al004d driver code. 16 reading. The Toshiba 32 CPU : TMP92ca25 on debugging through. NorFlash driven essentially the sam
PWM_VOICE
- 用LPC213X系列的PWM来产生语音。语音数据来源于PC机转换后得到的。最大可以是16位的。 由于是PWM所以输出端口需要低通滤波才能够得到比较干净的声音。 可以经过修改使用LPC2132以上的ARM的D/A来产生。 This project outputs audio on PWM0 using wave samples that are stored in the on-chip Flash ROM. -LPC213X series used to generate th
adcMain
- P87C591的a/d 转换程序，可在keil 51下调试运行，也可将其参数修改后作为函数使用。-P87C591 the a / d conversion, in the next 51 c51 debugging operation, but also its parameters can be modified as a function use.
colilo_serial.tar
- 针对freescale的coldfire系列mcu的开源bootloader源码colilo的优化代码，可以实现串口下载烧写和交叉调试器下载烧写，较多应用于uclinux，但略做修改可以用于任何需要做一些runtime setup的系统。-against the coldfire mcu series of open-source bootload er source colilo the optimized code can be downloaded Serial cross-burning
