标题: 发一个利用两个IIC数字光传感器（BH1750），进行平面定位
看了去年电赛，在网上查呢下，很少有资料分享，最近刚好在做可见光定位，所以先将写的两个IIC数字光传感器（BH1750）,采用差分方式进行定位程序分享下，还在改进中，完成后将全部开放！（用的是arduino UNOd的板子）

arduino源程序如下:
  1. #include <Wire.h> //BH1750 IIC Mode
  2. #include <math.h>
  3. #include <SPI.h>  
  4. #include <Wire.h>  
  5. #include <Adafruit_GFX.h>  
  6. #include <Adafruit_SSD1306.h>  
  7. int potpin=0;
  8. int a;//定义模拟接口0
  9. int now;
  10. int BH1750address0 = 0x5c; //setting i2c address
  11. int BH1750address1 = 0x23;
  12. uint16_t val0=0;
  13.   uint16_t val1=0;
  14. byte buff0[2];
  15. byte buff1[2];
  16. #define OLED_RESET 4  
  17. Adafruit_SSD1306 display(OLED_RESET);  
  18.   
  19. static const unsigned char PROGMEM logo[] =  
  20. {
