实现一个简易函数信号发生器的功能。系统上电后,默认输出低电平(无波形),默认初始频率为1KHz。波形输出频率可由开发板上的拨码开关SW0~SW3调节,可调范围为1KHz到2KHz,步进量为100Hz。波形由开发板上的DAC_A口输出。共有方波和三角波,正弦波三种波形可供选择,用户只需将开发板上的拨码开关SW6~SW7置成不同取值组合,就可以输出不同波形。其中方波的占空比可以用开发板上的按键开关BTN0~BTN1调节。系统重置按键为开发板上的按键开关BT7。另外,实验验收后我继续加入了锯齿波输出的

信号发生器设计
信号发生器由波形选择开关控制波形的输出, 分别能输出正弦波、方波和三角波三种波形, 波形的周期为2秒(由40M有源晶振分频控制)。考虑程序的容量,每种波形在一个周期内均取16个取样点,每个样点数据是8位(数值范围:00000000~11111111)。要求将D/A变换前的8位二进制数据(以十进制方式)输出到数码管动态演示出来。-Signal generator design
