Interrupt configuration. More...

Detailed Description

Interrupt configuration.

The interrupt enable flags apds99xx_int_config_t::als_int_en and apds99xx_int_config_t::prx_int_en control whether ALS and proximity sensor interrupts are enable.

The persistence values apds99xx_int_config_t::als_pers and apds99xx_int_config_t::prx_pers specify how many ALS or proximity values have to be outside of the thresholds defined by apds99xx_int_config_t::als_thresh_low and apds99xx_int_config_t::als_thresh_high or apds99xx_int_config_t::prx_thresh_low and apds99xx_int_config_t::prx_thresh_high.

Note
If the persistence values are 0, an interrupt is generated in each cycle at the end of the corresponding measurement step, regardless of the values and the defined threshold. The corresponding interrupt is thus used as a data-ready interrupt.

Field Documentation

◆ als_pers

uint8_t apds99xx_int_config_t::als_pers

Number of consecutive ALS values that have to be outside the thresholds to generate an interrupt:

Value Interrupt is generated
0 every cycle (ALS data-ready interrupt)
1...15 when n values are outside the thresholds

Definition at line 376 of file apds99xx.h.

◆ prx_pers

uint8_t apds99xx_int_config_t::prx_pers

Number of consecutive proximity values that have to be outside the thresholds to generate an interrupt:

Value Interrupt is generated
0 every cycle (PRX data-ready interrupt)
1, 2, 3 when 1, 2, or 3 values are outside the thresholds
4...15 when (n - 3) * 5 values are outside the thresholds
