Functions | |
int | Si1147_ConfigureDetection (I2C_TypeDef *i2c, uint8_t addr, int slow) |
Initializes and configures the Si1147 sensor. More... | |
int | Si1147_Detect_Device (I2C_TypeDef *i2c, uint8_t addr) |
Detects whether Si1147 is on the i2c bus. More... | |
int | Si1147_GetInterruptOutputEnable (I2C_TypeDef *i2c, uint8_t addr, int *enable) |
Get the enable status of the Si1147 interrupt pin. More... | |
int | Si1147_MeasureUVAndObjectPresent (I2C_TypeDef *i2c, uint8_t addr, uint16_t *uvIndex, int *objectDetect) |
Reads the UV measurement data and checks for object in proximity to the Si1147. More... | |
gesture_t | Si1147_NewSample (I2C_TypeDef *i2c, uint8_t addr, uint32_t timestamp) |
Reads new measurement data and processes a new sample. This function should be called every time an interrupt for a new sample is received. More... | |
int | Si1147_SetInterruptOutputEnable (I2C_TypeDef *i2c, uint8_t addr, int enable) |
Enables or disables the Si1147 interrupt pin. More... | |
