这个实际上只调到了初步的PCB可运行UART可用，其它还未真正调试，但其中的设计及PCB，若有用，哥们们可参考一下 因没完全调试，源代码工程有部分多余代码，工程文件需要重新整理一下，当然如果板子有用，其实可以完全根据原理自己建工程，压缩包内有完整SCH,PCB，包括电源5V,3.3V,RS232,RS485,CAN,SPI-Flash,USB,IO电路。 主要实现的功能是一个多IO，多个232/485，一个CAN通信。 其中数字Input检测，通过两个IO检测四种状态：高，低，悬空，检测单元有问题。 该单元在SCH&PCB目录下面有相应的Multisim仿真文件。 真值表： L1  H1  值 0    0   INX_LH1为高 0    1   检测单元问题，可能D6与D7之间断开或者INX_HL1电平 1    0   INX_HL1悬空，且检测单元OK；或者INX_HL1电平处于中值 1    1   INX_LH1为低

SMALL RTOS是为小ram系统单片机编写的,目前仅在51系列单片机上成功运行,还没有在其它单片机上移植(目前我仅有51和avr的开发系统).在小ram系统单片机如51系列上运行tcp/ip 协议栈是不太现实的.一般tcp/ip 协议栈需要在32位单片机上运行,在8位机上运行太勉强(51是8位机),除非您只运行ip协议.建议使用ucos/ii操作系统或是嵌入式linux,并选用arm或龙珠系列单片机-SMALL RTOS for small microcontrollers ram system, written in 51 series of microcontrollers currently only on the successful operation, no other MCU on the transplant (currently I am only 51 and avr development system). In the small ram System-on- machines such as the 51 series of films running on tcp/ip protocol stack is not very realistic. General tcp/ip protocol stack need to run 32-bit microcontrollers in the 8-bit machine running Taimian Jiang (51 is the 8-bit machine), unless you run only ip protocol is suggested. ucos/ii operating system or embedded linux, and use arm or Pearl Series MCU ..

本文是根据我学习ARM开发以来的一些经验总结，以自己设计的S3C44B0X板为例，给出入门上手的最基础知识。有些东西只是个人的主观认为，不一定准确，算作抛砖引玉吧，欢迎大家指正！-this paper is based on my study of the ARM since some experience to design its own board of S3C44B0X example, the entry is easily the most basic knowledge. Some things are just personal subjective view, is not necessarily accurate, it counted as something, we welcome correct!
