这是一个基于stm32 的频谱信号分析仪 彩屏显示 功能界面很漂亮 -This is a stm32 spectrum signal analyzer function interface is very beautiful color display

实现多通道ADC采集，通过图形界面显示，通过操作DDS信号发生器实现扫频，将天线阻抗信息现实吧到屏幕(Multi-channel ADC acquisition, through the graphical interface display, through the operation of DDS signal generator to achieve frequency sweep, the antenna impedance information to the screen reali
