Functions

int Si114x_ConfigureUV (int fullInit, HANDLE *handle)
 Initializes and configures the Si1146 sensor for UV index measurements.
 
int Si114x_EnableVisRange (int vis_range_bit)
 Set the VIS_RANGE bit of the optical sensor Si114x.
 
int Si114x_MeasureUVIndex (u16 *uvIndex)
 Reads the UV index measurement data from the Si114x.
 

Variables

static void * si114x_handle
 Si114x PGM toolkit functions uses a void* to pass hardware parameters through to the lower level i2c functions. This struct is passed down to the low level i2c functions using that pointer.
