Data Structures

struct  bh1750fvi_t
 Device descriptor for BH1570FVI devices. More...
 
struct  bh1750fvi_params_t
 Set of configuration parameters for BH1750FV devices. More...
 

Macros

#define BH1750FVI_DEFAULT_ADDR   BH1750FVI_ADDR_PIN_HIGH
 Default address of BH1750FVI sensors.
 
#define BH1750FVI_I2C_MAX_CLK   I2C_SPEED_FAST
 Maximum I2C bus speed to use with the device.
 
Possible I2C bus addresses of the device

The actual address of the device depends on the state of the ADDR pin.

#define BH1750FVI_ADDR_PIN_LOW   (0x5c)
 ADDR pin := 0.
 
#define BH1750FVI_ADDR_PIN_HIGH   (0x23)
 ADDR pin := 1.
