LIS2DH12 stops sending interrupt

Posted on December 04, 2017 at 08:07Good day allMy LIS2DH12 seems to lock up or stops responding, it is connected to STM32L152 which is set to go into STOPMODE and wakes on interrupt. An I/O pin is configured as an external interrupt and connected...

Hello, I am currently working with STM32 Nucleo L152RE and trying to use X Nucleo IKS01A1 board with it, i tried with IKS01A2,IKS01A3 and IKS02A1 packages and it didn't work.could someone please send me the old package used with IKS01A1. Thank you.

Digital MEMS microphone used for sound pressure level measurements

Hello everyone,I'm interfacing a digital MEMS microphone with a stm32l152re mcu cortex M3 using I2S with DMA In order to measure sound pressure level. the communication is based on acquiring PDM ( Pulse density modulation) values that represents the...
