前面有大佬驱动OLED，但是有点小问题，我这里解决了。

【实现步骤】
在前面ADC的基础上增加OLED模块
1、打开配置工具，添加i2c_master
2、按下图设置：

3、按下面配置管脚：

4、同步生成工程，回到keil。
5、新建oled.c,oled.h,oledfont.h并加入到工程中：

具体函数内容如下：
oled.c：

1. #include "oled.h"
   
2. #include "stdlib.h"
   
3. #include "oledfont.h"
   
4. 
   
5. #include "hal_data.h"
   
6. fsp_err_t err;
   
7. int  timeout_ms = 1000;
   
8. i2c_master_event_t i2c_event ;
   
9. //OLED的显存
   
10. //存放格式如下.
    
11. //[0]0 1 2 3 ... 127
    
12. //[1]0 1 2 3 ... 127
    
13. //[2]0 1 2 3 ... 127
    
14. //[3]0 1 2 3 ... 127
    
15. //[4]0 1 2 3 ... 127
    
16. //[5]0 1 2 3 ... 127
    
17. //[6]0 1 2 3 ... 127
    
18. //[7]0 1 2 3 ... 127

6、hal_enty.cn修改如下：

1. #include "hal_data.h"
   
2. #include <stdio.h>
   
3. #include "bsp_debug_uart.h"

7、下载到开发板，OLED可以点亮了：

8、接下来实动态显示电压：
改动bsp_adc.c如下：

1. void read_adc(void)
   
2. {
   
3.   fsp_err_t err = FSP_SUCCESS;
   
4.   double a0;
   
5.   uint16_t adc_data0=0;
   
6.   char vbuf[10];
   
7.   (void) R_ADC_ScanStart(&g_adc0_ctrl);
   
8.    scan_complete_flag = false;
   
9.   while (!scan_complete_flag)
   
10.   {
    
11.       /* Wait for callback to set flag. */
    
12.   }
    
13.   
    
14.   err = R_ADC_Read(&g_adc0_ctrl, ADC_CHANNEL_2, &adc_data0);
    
15.   assert(FSP_SUCCESS == err);
    
16.   a0=(double)(adc_data0/4095.0)*3.3;
    
17.   printf("v: %.03f \r\n",a0);
    
18.   sprintf(vbuf,"%.03fV",a0);
    
19.   OLED_ShowString(24,24,vbuf,24);
    
20. }

复制代码

实现效果如下：

这样就实现了电压表，与实际电压对比一下，准确度还是很高的。详情见视频。
