basys3的数字钟，可以显示00.00-59.59(Digital clock of basys3,It can display 00.00-59.59)

说明：  配置GTH ip的例子工程，选用7 series 芯片的GTH 113quad的四个通道，在程序中每个链路利用自己的恢复时钟进行数据解码，所以四个通道可以各自独立运行；成功工作在2.54Gb/s的链路状态，长时间（>24小时）的测试，误码率一直为0.(The GTH ip example project is configured with four channels of the GTH 113quad of the 7 series chip. Each link in the program uses its own recovery clock for data decoding, so the four channels can operate independently; the successful operation is at 2.54Gb/ The link state of s, long time (>24 hours) test, the bit error rate has been 0.)

实现可连续输入数据做三角函数变换处理，通过verilog代码实现，(It realizes triangular function transformation for continuous input data.)

HART 官方资料-HART协议采用基于Bell202标准的FSK频移键控信号，在低频的4-20mA模拟信号上叠加幅度为0.5mA的音频数字信号进行双向数字通讯，数据传输率为1.2kbps。(Official information-HART HART protocol based Bell202 standard frequency shift keying FSK signal at low frequencies 4-20mA analog signal amplitude is 0.5mA superimposed on the two-way audio digital signal digital communication, data transfer rate of 1.2kbps.)

用verilog实现ldpc最小和译码算法(This code is for the decode of MS-algorithm based on LDPC.)
