使用stm32f103rct6控制adf4351实现30M~~4G的正弦波

刚开始接触adf4351的时候，发现不知道如何去下手去编写程序，

怎么通过按键去实现控制产生不同的正弦波，

同时通过OLED显示。代码如下：

#include “delay.h”

#include “sys.h”

#include “lcd.h”

#include “touch.h”

#include “gui.h”

#include “test.h”

#include “MS5611.h”

#include “24l01.h”

#include “spi.h”

#include “string.h”

#include “usart.h”

#include “key.h”

#include “ADF4351.h”
