嵌入式开发前景和趋势，dos的基本知识。

计算机通过串口向2430发送命令，2430做相应的操作，并返回此时的状态-The computer through the serial port to send commands to the 2430, 2430 to do the appropriate operation and return to the state at this time

它是采用恩智浦 MRFC522 IC ISO14443、 微控制器 LPC1768、 接口 SSP0 的 RFID 基地卡读卡器。

HART协议由Rosemount公司开发且已向每个使用者开放HART协议采用标准的Bell 202频移键控信号以1200波特通信以低电平加载于4mA~20mA模拟信号上，由于载波信号的平均值为零所以它对模拟信号没有影响。-HART agreement develops by Rosemount Corporation also opened the HART agreement to each user to use the standard the Bell 202 frequency-shift keying signal increase by 1,200 bauds correspondences by the low level on the 4mA~20mA simulated signal, because intelligence signal mean value for zero therefore it has not affected to the simulated signal.

NUCLEUS下的一个文件组件,是POWERPC平台-NUCLEUS under a file components, is PowerPC platform

AVR系列源代码生成软件.rar 简单实用-AVR series of source code generation software. Rar simple and practical

用于PLC或RTU上的MODBUS 通信代码,可以作为MODBUS程序开发参考-For the PLC or RTU

所有的单片机都会涉及到232 或者485通讯,而通讯中又不可避免的出现错误.本例就给出了一个现成的校验软件.完成串口通讯,并且进行crc,累加和,异或和等效验结果-All of the single-chip will be 232 or 485 relating to communications, and communications also inevitable error. In this case on a given off-the-shelf software validation. The completion of serial communications, and to carry out crc, cumulative and, XOR and equivalent examination results
