VEML6035 - Ambient Light Sensor#

sl_veml6035_integration_time_t#

sl_veml6035_integration_time_t

Integration time settings.

sl_veml6035_psm_wait_t#

sl_veml6035_psm_wait_t

Wait time between measurements in power save mode.

sl_veml6035_als_pers_t#

sl_veml6035_als_pers_t

Interrupt persistence settings.

sl_veml6035_init#

sl_status_t sl_veml6035_init (sl_i2cspm_t * i2cspm, bool white_enable)

Initialize and enable the VEML6035 sensor to operate in normal mode.

Note

• This function configures the sensor to a default integration time of 100 ms and the lowest possible sensitivity configuration in order to achieve maximum illumination range. If the lux count is too low, consider configuring sensitivity settings with sl_veml6035_configure_sensitivity.

sl_veml6035_get_als_lux#

sl_status_t sl_veml6035_get_als_lux (sl_i2cspm_t * i2cspm, float * lux)

Retrieve the sample counts from the ALS channel and calculate the lux value.

sl_veml6035_get_white_lux#

sl_status_t sl_veml6035_get_white_lux (sl_i2cspm_t * i2cspm, float * lux)

Retrieve the sample counts from the WHITE channel and calculate the lux vaule.

sl_veml6035_enable_sensor#

sl_status_t sl_veml6035_enable_sensor (sl_i2cspm_t * i2cspm, bool enable)

Enable or disable sensor measurements.

Note

• Disabling the sensor does not make sensor lose its configuration and last measurement values.

sl_veml6035_reset#

sl_status_t sl_veml6035_reset (sl_i2cspm_t * i2cspm)

Reset sensor configuration to the same state as after a power on reset.

Note

• This function does not clear data output registers, or interrupt status register.

sl_veml6035_configure_sensitivity#

sl_status_t sl_veml6035_configure_sensitivity (sl_i2cspm_t * i2cspm, bool low_sensitivity, uint8_t gain)

Configure sensor sensitivity settings.

Note

• A low sensitivity results in a larger light sensing range, while a high sensitivity yields a higher resolution at low illumination levels.

sl_veml6035_configure_integration_time#

sl_status_t sl_veml6035_configure_integration_time (sl_i2cspm_t * i2cspm, sl_veml6035_integration_time_t integration_time)

Set integration time.

Note

• The default integration time is 100ms. This can be increased to achieve a higher resolution, or decreased to achieve a faster measurement rate.

sl_veml6035_configure_psm#

sl_status_t sl_veml6035_configure_psm (sl_i2cspm_t * i2cspm, sl_veml6035_psm_wait_t psm_wait, bool enable)

Enable power save mode, with a defined wait time between measurements.

sl_veml6035_configure_interrupt_mode#

sl_status_t sl_veml6035_configure_interrupt_mode (sl_i2cspm_t * i2cspm, uint16_t high_threshold, uint16_t low_threshold, sl_veml6035_als_pers_t persistence, bool white_enable, bool enable)

Configure interrupt mode.

sl_veml6035_enable_interrupt_mode#

sl_status_t sl_veml6035_enable_interrupt_mode (sl_i2cspm_t * i2cspm, bool enable)

Enable or disable threshold interrupts.

sl_veml6035_read_interrupt_status#

sl_status_t sl_veml6035_read_interrupt_status (sl_i2cspm_t * i2cspm, bool * threshold_low, bool * threshold_high)

Read threshold interrupt status register and return interrupt status for high and low threshold.
