此为我们组在09年全国电设做的数字幅频均衡器的基于周立功ARM1138的代码，主要文件为里面的FIR.c（数字IIR滤波）和DAC904.c(DAC904的驱动)-This is our group code about amplitude-frequency based on ZLG ARM1138in 2009 native electric designequalizer ,inside the main document fo

这个是我自己用VHDL语言写的两相数字信号发生器程序 D/A用的是DAC904-This is for my own use VHDL, written procedures for two-phase digital signal generator D/A using a DAC904

这是DA904的AD10的板子，画板子的时候可以借鉴下-This is the DA904 AD10 board

DAC904的FPGA驱动代码，开发环境是Verilog，quartus。所用试验板为DE0-DAC904 driver code for FPGA development environment is Verilog, quartus. The test plates used to DE0
