8*8键盘矩阵 用作单片机 8*8键盘矩阵 用作单片机 8*8键盘矩阵 用作单片机...

说明：  用verilog编辑的中值滤波器！语言旁表有注释方便理解！(Using Verilog editor median filter! Language beside the table annotated to facilitate understanding!)

Very suitable for the study using computer vision, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. The performance of the program has reached a high level.

提供了利用 GPIF 对 FX2LP 与同步 FIFO CY7C4625-15AC 之间的接口进行设计的源代码(Provides for the use of GPIF FX2LP and synchronization FIFO CY7C4625-15AC to design the interface between the source code)

中央空调的控制，3级控制系统，这个是中间控制的vhdl源代码-Central air-conditioning control, 3 control system, this is the middle of the control of vhdl source code

用fpga芯片使用vhdl语言对AD转换芯片ADC0809进行控制(Using the fpga chip use language of VHDL AD transform chip ADC0809 control)

用FPGA于32进行SPI单向通信，FPGA向32放松发送数据(One-way SPI communication is carried out in 32 with FPGA, and data is sent to 32 with ease by FPGA.)

说明：  通过一个计数器来实现输出信号的占空比要求，可以将duty_cycle分配到拨码开关上,LED分配到发光二极管上,然后调节拨码开关,即可看到LED的亮度发生变化.(The duty cycle of the output signal can be assigned to the dial switch by a counter, and the LED can be assigned to the light emitting diode. Then the brightness of the LED can be seen by adjusting the dial switch.)
