生成多项式的最高位必须是1。例如:CRC
生成多项式的最高位必须是1。例如:CRC-CCITT标准的16位生成多项式:g(x)= x16+x12+x1+1;阶数r = 16
即:0x11021.最高位通常为1。-Generating polynomial must be the highest one. For example: CRC-CCITT standard 16-bit generation polynomial: g (x) = x16+ X12+ X1+ 1 order of r = 16 that is: 0x11021. Highest one usually.

通常的汉字显示方式是先根据所需要的汉字提取汉字点阵(如16×16点阵),将点阵文件存入ROM,形成新的汉字编码;而在使用时刚需要先根据新的汉字编码组成语句,再由MCU根据新编码提取相应的点阵进行汉字显示。在这种显示方式中,如果使用的流字数量较大或语句较多时,利用汉字的新编码组成语句将是一件十分繁琐而枯燥的工作。针对这种情况,本文提出了一种十分简单的方式――直接利用PC机的汉字内码作为单片机系统的编码。-Chinese characters are usually displayed in accordance with the need to first extract of the Chinese character dot-matrix (such as 16 × 16 dot matrix), will be deposited into the matrix documents ROM, a new Chinese character encoding while just need to use the Chinese characters according to the new code composed of statements, and then by the MCU according to the new code to extract the corresponding Chinese character dot-matrix display. In this show the way, if you use the word flow statement number of the larger or more, the use of Chinese characters composed of a new coding language will be a very tedious and boring work. In view of this situation, this paper presents a very simple way- direct access to PC-code character encoding as a single-chip microcomputer system.

汽车PKE工程 密钥转发器程序 通过车厂认证的哦
The PCF7991AT is a fully integrated Advanced Basestation IC, ABIC, designed for car immobilizer systems providing read and write access to an identification transponder. The device is intended for use with the NXP transponder family (PCF79xx) as well as other transponder types operating at 125 kHz and employing ASK, Amplitude Shift Keying for write and AM/PM for the read operation. The receiver characteristics (amplifier gain,filter cutoff frequencies) can be optimized to system and transponder requirements. The PCF7991AT IC is designed for easy integration into immobilizer read/write and read-only systems featuring a high degree of integration and very low external component count. The device integrates a powerful antenna driver/modulator, a low-noise adaptive sampling time demodulator, programmable filters/amplifier and digitizer, required to design high-performance basestations. A three wire microcontroller interface is provided for programming the
