SD 基于引用 verilog CRC7 计算器

FPGA按键延时模块，产生key_value和key_flag 可直接例化调用(The key delay module of FPGA)

Verilog实现按键消抖，工程，已下板验证通过。(Verilog achieves keystroke jitter elimination. The project has been validated on the lower board.)

说明：  PF6182是一款很好的DC-DC同步降压IC。输出电压可调整，电流达2A。非常好用(PF6182 is a good DC-DC synchronous buck IC. Adjustable output voltage and current up to 2A. Very easy to use)

SRAM的读写代码，对SRAM进行了乒乓操作，用VHDL语言进行设计，很有参考价值，甚至可以直接复制代码来进行自己的设计(SRAM read and write code, ping-pong operation carried out on the SRAM, using VHDL language design, of great reference value, or even directly copy the code to carry out their own designs)

这是基于FPGA的示波器设计，采用verilog描述，硬件为AC620开发板和小梅哥自主设计的ADM9226模块，能基本实现示波器的测量功能。

高精度小数除法器设计与实现。 在FPGA开发板上实现小数除法器，输入输出信号N_in [15:0], D_in[15:0]，N_in[15:0]小于D_in，即被除数小于除数，输出商Q_out[15:0]中Q[15]一定为0，Q[14:0]为商的小数部分。输入和计算结果通过VGA显示。(Precision fractional divider design and implementation. In the FPGA development board fractional divider, input and output signals N_in [15: 0], D_in [15: 0], N_in [15: 0] less than D_in, ie the dividend is less than the divisor, quotient output Q_out [15: 0] in Q [15] necessarily 0, Q [14: 0] for the business of the fractional part. Input and calculation results display by VGA.)
