Hi all,I'm using lis2dw12 sensor and interfaced with SPI. In which SPI mode i can get proper data from the sensor?CPHA = 0, CPOL = 0;CPHA = 0, CPOL = 1;CPHA = 1, CPOL = 0;CPHA = 1, CPOL = 1;Thanks and regards,Basavanagouda

VL53L1X readings unreliable when no object in front

I am testing the VL53L1X in medium measurement mode at 200ms timing budget I get 140cm weak return signal value even when there is no object in front.In long measurement mode with 300ms timing budget with no object infront the values I get are jitter...
