his project was built and tested with WinAVR-20060125. Make sure the MCU target define in the Makefiles corresponds to the AVR you are using!! To build the code, just install WinAVR and run "make" from the console in echomaster and echoslave subdirs. "make program" will program the device if you have a AVRISP attached. Remember to set the AVR device to at least 8MHz. The AVR may use the programmable clock from MC1319x, just remember to check if the MC1319x and SPI communication is working FIRST! Otherwise you wont get any clock signal to the AVR and then you can t program it or reset the fuses! The MC1319x has default clock output of 32kHz so you will have to set your programmer to a very low frequency (<=32kHz/4) to be able to program it while it is running on that!

crc任意位生成多项式 任意位运算 自适应算法 循环冗余校验码(CRC,Cyclic Redundancy Code)是采用多项式的 编码方式,这种方法把要发送的数据看成是一个多项式的系数 ,数据为bn-1bn-2…b1b0 (其中为0或1),则其对应的多项式为: bn-1Xn-1+bn-2Xn-2+…+b1X+b0 例如:数据“10010101”可以写为多项式 X7+X4+X2+1。 循环冗余校验CRC 循环冗余校验方法的原理如下: (1) 设要发送的数据对应的多项式为P(x)。 (2) 发送方和接收方约定一个生成多项式G(x),设该生成多项式 的最高次幂为r。 (3) 在数据块的末尾添加r个0,则其相对应的多项式为M(x)=XrP(x) 。(左移r位) (4) 用M(x)除以G(x),获得商Q(x)和余式R(x),则 M(x)=Q(x) ×G(x)+R(x)。 (5) 令T(x)=M(x)+R(x),采用模2运算,T(x)所对应的数据是在原数 据块的末尾加上余式所对应的数据得到的。 (6) 发送T(x)所对应的数据。 (7) 设接收端接收到的数据对应的多项式为T’(x),将T’(x)除以G(x) ,若余式为0,则认为没有错误,否则认为有错。

假定已经有许多应用采用了程序1 - 1 5中所定义的C u r r e n c y类,现在我们想要对C u r r e n c y类 的描述进行修改,使其应用频率最高的两个函数A d d和I n c r e m e n t可以运行得更快,从而提高应 用程序的执行速度。由于用户仅能通过p u b l i c部分所提供的接口与C u r r e n c y类进行交互,
