Hello,I use the accelerometer LSM6DSOX. I want to get an interruption when the norm is above 8g. So I try to use the FSM and configure it. When I flash (for the first time) the system, everything works perfect ! But when I remove my battery and put i...

Hello,I have an issue with the pressure sensor LPS25HB. It looks like the LPS25HB don't work properly when the rest of the circuit drain current from the coin cell.I confirm it is a problem related to the powering of the pressure sensor LPS25HB : Whe...

Hello,I made a new PCB design using the LPS25HB (see PCB prints attached). On this new PCB, the LPS25HB works fine when I put a new coin cell (I get correct pressure value to compute a height difference of 50cm so I use the sensor at its maximum perf...

Hello, I work on a wearable solution with your pressure sensor LPS25HB. I have a problem with the precision of the sensor. Using the LPS25HB adapter board (STEVAL-MK1165V1), I have sufficient precision to detect a high difference of 50cm (I use the b...

Hello,Yes I know that, that's why I configure my FSM at the start of my main loop. So on restart, the accelerometer is reconfigured. I found a solution, with a software reset of the LSMDSOX before configure it, it works properly.Thank you for your ti...

Hello, I assemble a new PCB board and change a bit the design. I removed routes and via under the pressure sensor. I am still not in a case so the pressure sensor should work correctly (as your adapter board). On this new PCB, the LPS25HB works fine ...

No problem ! Great support comes with good information =) Thank you for your help !No we didn't put conformal coating after soldering. Do you mean that conformal coating could close the holes ? or do we need it to protect the sensor ?So you believe t...

LSM6DSOX : FSM interruption working only once after flashing. When I turn off and turn on again the device, the FSM does not work anymore ... Did I make a mistake in FSM configuration ?

Reliability issues of the LPS25HB when the rest of the circuit drain current from the coin cell

Pressure sensor LPS25HB don't work properly when supplied from a coin cell in my design . Pressure values are wrong. It looks like an energy issue ... the sensor has not enough energy to work properly ?

Can PCB design (not following all guidelines) really affect the performance (precision) of the LPS25HB sensor when using it at highest precision ? Can the LPS25HB works properly at best precision without vent aperture ? in a waterproof ip65 case ?
