GPS 导航器TFT 驱动源程序。主CPU为ATmel的AT91sam9261（ARM926的内核）(TFT GPS navigation device driver source code. CPU for the AT91sam9261 ATmel (ARM926 the kernel))

说明：  基于PCF8591数模转换和DDS技术的信号发生器系统设计(Design of Signal Generator System Based on PCF8591 Digital-to-Analog Conversion and DDS Technology)

32位/33M 从模式(target)PCI接口参考设计，Lattice提供。由于PCI时序较复杂，此设计仅能供参考-32/route from the model (target) PCI reference design, Lattice provided. Because PCI timing more complicated, and the design for reference only

adc采集多路采集多通道基于dma的adc采集(ADC acquisition, multi-channel acquisition and multi-channel acquisition)

说明：  SDRAM的驱动程序，主要是对SDRAM各类状态进行驱动，有刷新模块、读、写模块等。(The driver of SDRAM mainly drives various states of SDRAM, including refresh module, read and write module.)

此RS232通信协议用VHDL语言实现，基于Altium Designer公司的Protel DXP开发平台。本人是基于Nanaboard开发板编写的程序，其他用户只需要对配置文件进行修改即可用于其他电路板。-RS232 communication protocol with the VHDL language, based on the Altium Designer

Verilog投币式手机充电仪 清华大学数字电子技术基础课程EDA大作业。刚上电数码管全灭，按开始键后，数码管显示全为0。输入一定数额，数码管显示该数额的两倍对应的时间，按确认后开始倒计时。输入数额最多为20。若10秒没有按键，数码管全灭。(Verilog coin operated cell phone charger EDA major homework of digital electronic technology foundation course, Tsinghua University. Just put on the digital tube completely extinguished, press the start button, the digital tube display is 0. Enter a certain amount, the digital tube shows the amount of double the corresponding time, according to the confirmation began countdown. The maximum amount of input is 20. If there is no button in 10 seconds, the digital tube will die out.)

这是一个基于Quartus2 开发环境的4输入加法器( 4adder basic on Quartus2)
