SPI接口代码

说明：  使用verilog实现的双电梯控制器，1-9层，仿真通过(a bi-elevator controller written in VerilgHDL, which has floor1-9, simulation passed)

This CAN Controller was tested with the Bosch VHDL Reference Model and passed all the tests. Because of the licensing issue it can not be published on the Opencores web site. The Can Controller was also implemented in real HW (12 boards were constantly talking to each other). The included test bench is not a real test bench and should be improved. However a volunteer is needed for such a job. I can provide some help but am not willing to write it by myself.

这是fpga按键消抖的源代码，在很多fpga按键实验中都可以用到，能够进行代码移植。(This is the source code of the FPGA buttons, in many FPGA key experiments can be used, and can carry out code.)

FPGA功耗分析工具EPE用于分析FPGA系统的功耗(FPGA power analysis tools EPE is used to analyze the power consumption of the FPGA system)

verilog编写的RTC（实时时钟）包含APB总线接口、时钟计时部分等(verilog prepared by the RTC (real time clock) contains APB bus interface, clock time some other)

This is a simple verilog code for stopwatch undre xlinx ISE webpack based for NEXYS3 board.

本资源是基于FPGA的一个硬件串口模块设计，其中包括的模块有：datagene.v,uart_speed_select.v,fifo_232.v,uart_ctrl.v,uart_tx.v,uartfifo.v,其中uartfifo.v为顶层模块，它调用上述的一些模块，完成相关的功能，本设计主要实现的功能是串口的字符串发送。不是简单的单字节发送，而是完成字符串的发送。

这是 picoblaze 的线跟踪 bot 程序集代码。
