用OV7720制作摄像头的详细电路原理图 ，以及初始化代码，使用范例。-OV7720 camera with the production of a detailed circuit schematic diagram, as well as initialization code, the use of examples.

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！经测试也适应于恒丰公司S344BOX等采公板设计的开发板。在其上电以后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。-this code under the SDT2.51 debugging through, I can blame the ARM DEVELOP BOARD V1.0 above Run! After tests also adapted to Prudential and other mining companies S344BOX public board design development board. In his last-- after about LED blinks, Serial 0 then the output will be some system information through serial terminal and system interaction, can test the 320 X240 STN LCD, including graphic display function, ascii character display function.

ARM和CPLD的JTAG的原理图，以及PCB图，为公司做的，顺便发出来，有需要的可以下栽-ARM and CPLD schematic diagram of the JTAG and the PCB map, to do for the company, and the way it comes, there is a need can下栽
