ARM7 S3C44B0X的键盘和LED驱动实验代码

ARM处理器软中断处理。a_swi.s文件是最开始处理的SWI句柄,用ARM汇编指令编写。c_swi.c文件是在执行a_swi.s文件之后调用执行的C语言SWI句柄。 -ARM processor soft interrupt handling. a_swi.s document is the beginning of the SWI handler deal with the preparation of ARM compilation directives. c_swi.c document is in the implementation of a_swi.s document called the C language implementation of SWI handler.

有了这个库， 外部 SD-RAM 可以 上使用 STM32F429 发现 板. RAM

这是一个工业控制软件的有机组成部分，该软件经长期使用，运行可靠-This is an industrial control software, an integral part of the software by the long-term use, reliable operation

1. T0_ASM.rar, (带中文注释的C51语言例程), 利用定时器0中断实现LED灯的简单控制。 2. T0_C51.rar, (带中文注释的51汇编语言例程), 利用定时器0中断实现LED灯的简单控制。 两个同样功能的timer0中断程序都在MCU51-63K仿真器下通过实验。-1. T0_ASM.rar, (with Chinese comments C51 language routines), use of the timer 0 interrupt LED lamps to achieve a simple control. 2. T0_C51.rar, (with English Notes 51 assembly language routines), use of the timer 0 interrupt LED lamps to achieve a simple control. Two same functions Timer0 interrupt procedures are MCU51-63K emulator through the experiment.

资源描述通过定时器控制PWM，可控制PWM个数，使用的是STM32F407ZET6

基于44b0的arpscan程序，包括基本操作-The 44b0-based arpscan procedures, including basic operation

initial flash and sdram

uboot很好的bootload资料！周立功公司出的！感觉不错！-uboot Bootload good information! Week Ligong companies out! Feel good!

ARM汇编指令（中文版）.chm含有详细的ARM指令集及Thumb指令集的中文说明-ARM compilation directives (Chinese version). Chm contain detailed ARM instruction set and the Thumb instruction set of the Chinese description

STM32是以Cortex-M3为核的处理器，该例程介绍STM32下如何对SPI进行操作。SPI适合于较长距离，高速通信。如SD，解码芯片等等。-Cortex-M3 based STM32-core processor for the routine introduction STM32 how to operate on the SPI. SPI is suitable for long distance, high-speed communications. Such as SD, decoder chip and so on.
