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.)

FPGA控制AG9226进行采样的代码,并用signaltap测试了一下其正确性

辛辛苦苦的作品应用于DE2 的 开发。。希望对大家有用。-hard work for Dictyophora development. . We hope that the right useful.

FPGA上的VERILOG语言编程。通过查找表实现直接数字频率合成。在主控部分通过键盘选择正弦波，方波，三角波，斜波，以及四种波形的任意两种的叠加，以及四种波形的叠加；通过控制频率控制字C的大小，以控制输出波形频率，实现1Hz的微调；通过地址变换实现波形相位256级可调；通过DAC0832使波形幅值256级可调；通过FPGA内部RAM实现波形存储回放；并实现了每秒100HZ扫频。(FPGA on the verilog language programming. Lookup table through direct digital frequency synthesis. In part through the control of the keyboard to choose sine, square, triangle wave, sloping wave, and four arbitrary waveform two superposed and the stack of four waveform; by controlling the frequency control word on the size, in order to control the output waveform frequency, 1 Hz to achieve the fine-tuning; Address transform through waveform phase adjustable 256; DAC0832 so through waveform amplitude adjustable 256; FPGA through internal RAM to the waveform storage intervals; and achieve a 100 per second sweep 9999.)
