BVADPCM data noisy when Sensor Tile is soldered to cradle

Posted on January 25, 2018 at 12:52When the Sensor tile is hooked to Expansion board, the FP ALL MEMS firmware and the custom firmware is able to stream the audio data to STBlue MS app. However the above said firmware would stream noisy data when th...

H3LIS331DL Turn On time

Posted on February 09, 2018 at 15:20Hi all,I have been working on H3LIS331DL sensor. I am missing one clarification from datasheet of H3LIS331DL.On Page 10 of datasheet H3LIS331DL, Turn on time should be 1/ODR + 1ms.It is clear that based on ODR rat...

LIS3DH as movement/tilt sensor

Posted on February 05, 2018 at 19:54Hi ALL, I bought the LIS3DH development kit.I want to use it as a sensor that will wake my MCU with interrupt when someone moved my board or tilt it.I have some constrains:1. I need low consumption current with my...

LSM303AGR Low ESR capacitor

Posted on February 09, 2018 at 10:31Hello, in the LSM303AGR datasheet a low esr capcitor (220nF) is requested on pin5. But no more indication are given.On which frequency the esr must be < 200mOhm ?Thanks for the help.#lsm303agr

Recommended LIS2DH Setup

Posted on November 01, 2017 at 18:16I have an LIS2DH device in my design and it's working - sort of.  I was given some LIS3DH C driver code which I'm using under the advice that the LIS2DH is register-compatible with the LIS3DH.So my requirement is ...

LIS2DH self test & interrupt

Posted on February 06, 2018 at 09:55Hi,I am looking to test if the interrupt 1 and 2 are working correctly on a LIS2DH.Is it possible to trigger interrupts with the self test functon ?Thank you for the help#lis2dh #self-test #interrput

STPM10 does not start immediately after RC startup procedure

Posted on March 08, 2017 at 10:53Hello all,I want to use ♯ with internal RC oscillator. When I started using ♯ , I prepared a communication library that works well without using the internal RC oscillator. I checked all communication using oscillosc...
