| 摘 要： | 利用OneWireBus串行传输iButton器件数据，CRC校验是必不可少的。有二种CRC校验实现方案：硬件实现和软件实现方案。软件方案中，又有几种不同的方法，软件实现节省了专门的硬件校验电路。DOWCRC用查表法速度更快，CRC16用公式法更优越，既节省存储空间又提高校验速度。

| Abstract: | ERE is necessary for transmitting data of iButton device based on One Wire Bus. There are both hardware and software solution of the CRC process. There are several different methods by software. The software solution is frugal of special checking circuit. Looking up table method is the fastest for DOWCRC. Computation method using formula not only saves memory space but also improves the check speed for CRC16. |
