STK6031 MCU,64KFlash UART 程序

优龙开发板YL2410的bios完整代码，即bootloader的代码，对开发板的学习很有用的-YL2410 bootloader

此代码是在S3C44B0公板上的测试程序，包括boodloader,flash,lcd,common等-This code is in the public board S3C44B0 testing procedures, including boodloader, flash, lcd, common, etc.

这是一个实现向一块ARM板上移植uclinux2.0的程序,通过PC机的串口1可实现向目标板的flash里面写入uclinux2.0- This is a realization transplants uclinux2.0 together to the ARM board on the procedure, 1 may realize through the PC machine string mouth to inside goal board flash reads in uclinux2.0

网上搜集的整套s3c2440中文手册。是目前最完整的了。介绍了s3c2440详细技术资料。-Internet to collect the package of s3c2440 Chinese manual. Is the most complete of the. Introduced s3c2440 detailed technical information.

1.此代码在SDT2.51下调试通过，可以在我的板子ARM DEVELOP BOARD V1.0上面跑！其上电以后LED会闪烁一下，接着串口0会输出一些系统信息 可以通过串口终端与系统交互，可以测试320X240 STN LCD,包括图形显示函数，ascii字符显示函数。-1. This code debugging under the SDT2.51 passed, in my plank ARM DEVELOP BOARD V1.0 above run! After its power LED flashes that went 0 serial output will be some system information through serial terminal and system interaction, can test 320x240 STN LCD, including graphics function, ascii character display function.

基于LPC2119 CanBus通讯程序-based LPC2119 Canbus communication procedures

周立功 GUI在ucosii上的应用，内含源码及说明文档-weeks ucosii meritorious GUI in the application includes source code and documentation

基于STM32的4轴步进电机加减速控制全套工程源码，共有两套；一套是STM32F103的，另外一套是STM32F405的；可以同时控制4轴步进电机进行加减速；速率可以达到100K以上；源码算法是基于《AVR446: Linear speed control of stepper motor》

  基于华邦W90P710芯片，包括十五个测试实验。流水灯，键盘控制，LCD显示字符和图片控制，KPI,USI，外部中断，定时器，I2C实验，串口通信实验等，对于基于W90P710的arm的学习的朋友相信会有很大帮助。

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 trip of less than 2000 operating system, cleverly using ARM9 CPU memory management unit (MMU) to achieve the switching process. ARM9 4G virtual address can be divided into 128 process space, each 32M. While their virtual address (VA) are 0- (32M-1), but the corresponding MVA (Modified Virtual address, and by the virtual address VA and the process of portfolio from PID) not the same, set MVA corresponding page table at the different physical address can be very easy to let the the process of separating the mutual operation of space. Code rarely Notes rich, in hopes of understanding the operating system, understanding the ARM architecture friends help.
