此项目用来跟踪车辆使用的 gsm 和 gps （全球定位系统）。gps 模块，gsm 模块和单片机集都放置在车辆跟踪它的位置。

简单的源代码写在codevisionavr显示如何驱动键盘和模拟proteus。

本文介绍了如何用AD识别用户输入的键盘的方法，较之点阵识别有其不可替代的优势；因为如果用4*4的话须消耗8个I/O口，而如果系统有AD功能的话就可能轻松解决了。 单片机8051F330发给ARM然后发给电脑。 其原理就是利用电阻的分压，按键时产生不同的电压，再用中断快速读取电压；然后对其进行编码，通过串口软件EASYARM在个人电脑里显示；经实验观察，效果还可以。 -This article describes how to use AD to identify the user s keyboard input methods, compared with dot-matrix recognition has its irreplaceable advantages because if we use 4* 4, then to be consumed eight I/O port, and if the system function in AD, then on may be easily resolved. Singlechip 8051F330 distributed computer and then distributed to ARM. Its principle is to use the sub-ballast resistor, when keys have different voltage, and then quickly read voltage interruption then encode, through the serial port software EASYARM in the personal computer display by experimental observation, the effect can also be.

改写的U-boot for s3c4510 (注意此源码是在windows下压缩了)。 1、支持串口下载，ftp下载。 2、flash操作。 3、总之，u-boot是一个可移植在多种单片机上的bootloader。其功能特别强大。 4、本移植针对s3C4510,flash 1片2M　16位宽度，SDRAM 1片16M　16宽度。网络物理层RTL8019。 5、你可以直接windows解压后，把u-boot.bin烧写到FLASH的0x0,或放到redhat 9下重新make.-rewrite the U-boot for Porting (Note that this source is under pressure in windows a shrinking). A support serial download, ftp download. 2, flash operation. 3, in short, u-boot is a portable in a variety of microcontroller on the Bootloader. Its function was particularly strong. 4, the transplant against s3C4510, flash a 2M 16 width, 16M SDRAM a width of 16. RTL8019 network physical layer. 5, you can directly windows unpacked, put u-boot.bin burning FLASH to the 0x0, redhat 9 or put under re-make.
