Resolved! How do you use the .ucf file generated by the UNICO GUI and why do the outputs seem to make no sense, comparing it to the register description found in the data sheet?

I am working with the Sensortile.Box right now. More specifically, I want to configure the pedometer function with the MLC to work with certain configurations. The accelerometer has to be set to 16g Full Scale, because of a fall-detection functionali...

Hi Everybody,I have a weird problem initializing LIS2DH12 in FIFO stream mode with the official ST driver. This is my initialization code:bool lis2dh12wInit(lis2dh12w_cfg_t *cfg) { uint8_t whoamI; lis2dh12_ctrl_reg3_t ctrl_reg3;   /* set read a...

LIS2DH12 reset (BOOT in CTRL_REG5)

Hallo,I am wondering how can I reset the LIS2DH12 accelerometer. I am using the official ST driver which preserves register contents on nearly all actions (read-modify-write), and the MCU in hardware may perform a soft reset when it tries to re-initi...

Hello ST Experts , I have a stm32f745 ,which creates a single file and writes a string array in SD card using FATFS, but now I want to create multiple files which appends the PDM2PCM middleware converted PCM buffer values. from the 3 MEMS acquired?

Certain things which are unclear are :1) When I increase the size of the PDM buffer and PCM buffer say to 2000 ,4096 to collect more samples for storing to convert them into a larger file into.wav or mp3 , I find no creation of the file in SD card .T...
