在STM32上移植的STemWin图形操作界面，带触摸，可以直接使用-STM32 on the transplant STemWin graphics interface, with touch, you can directly use

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

STEMWIN中文手册,可以在开发stemwin图形界面时做一个很好的参考(STEMWIN Chinese manual, you can make a good reference when developing the stemwin graphical interface)
