I2C接口标准建模源码,I2C interface standard modeling source-I2C interface standard modeling source

基于fpga和51单片机的等精度频率计，通过fpga对信号进行采集，数据传给单片机计算，再由12864进行显示，可进行频率，周期，脉宽，占空比，幅值等的测量。(Fpga and 51 microcontroller based precision frequency meter, through fpga for signal acquisition, data to the microcontroller to calculate, and then by 12864 for display, can be measured frequency, period, pulse width, duty cycle, the amplitude and the like.)

FPGA来实现数据采集，AD采用TI公司的THS1206，高速并行AD，内含16字FIFO，降低硬件复杂度。(FPGA to realize data acquisition, AD using TI company s THS1206, high-speed parallel AD, containing the 16-character FIFO, to reduce hardware complexity.)

文件名：lcd1602lib.h 内　容：1602液晶的控制端口、数据端口和相关操作(The file name: lcd1602lib. H * inside let: 1602 LCD control port, data port and related operations )

说明：  按键消抖,避免按键抖动造成信号误触发，增大按键输入的可靠性(Key jitter elimination, avoid key jitter caused by signal error trigger, increase the reliability of key input)

these are verilog files but i am uploading in text(notepad) format

基于用户自定义模块的实时时钟的设计；Qsys硬件设计；(Custom real-time clock module-based design Qsys hardware design )

该程序用来实现电话计时以算取费用，比较简单(telephone cost metering verilog code)

这是FPGA的一个简单例程，LED键盘显示程序，非常时候大家入门学习-This is the FPGA, a simple routine, LED keyboard display program, very time we started to learn

一个用Verilog编写的编帧、解帧及码速匹配的程序，相当经典(Verilog prepared with a series of frames, frames and solutions yards speed matching procedures, rather classic!)
