Hi All,I want to port VL53L4CX bare driver to my M0+ MCU (36KB SRAM) however it cannot fit into RAM (.bss)What's RAM requirement of VL53L4CX bare driver ?(I used VL53L1CX ULD and VL53L4CD ULD driver that's ok) or how to trim down the memory requireme...

Hi All,I started with example to make STHS34PF80 presence detection working.Now I tried to add effective presence detection range.Where should I start ? Is there a suggested process ?

Hi All,I need a mechanism to detect motionless for 10s to make device enter power saving mode.For lis2dh12, I can use HPF with low x,y,z threshold and duration to detect an event that motionless for 10s.However I need more low power accelerometer lis...

we want to use VL53L3CX however its driver is too large for MCU, we like VL53L1X Ultra Light Driver idea, is it possible that ST can provide ULD for VL53L3CX ?

Hi John, I found the root cause of the RAM issue isVL53LX_Dev_tA single instance takes around 9k which it too big for MCU SRAM.It there any way to trim it down or fine tune to fit limited SRAM ?

My existing code is based on this example, however the presence detection range is around 1.2 meters.I want to extend the range up to 2.5~3 meters however there is no criteria in example what parameters to tune.

Hi Sir,For a. I think it should be clearly documented in datasheet instead of only in ap note.If I missed ap note and follow only datasheet I'll never get it out.BR,Sam

Hi Sir,Thanks for your help. I think p.33 Figure 14 of app note helps a lot.However there is something to feedbacka. there should be more highlight that you need to enable both INT_SLEEP_CHG and INT_SLEEP_STATE to get INT_SLEEP_STATE pulse.(I tried h...

I wish vl53l3cx can come out a reduced size API like VL53L1X did -- VL53L1X ULD API (Ultra Lite Driver API).That will be great.sam
