the sensory library does not work at all.

Hello, I'm working on a project involving voice recognition. So, I used the stm32 sensory library to complete this project and the MP23DB02MM digital MEMS PDM microphone. However, I only found one example that used STM32H747I-DISCO, so I ported it to...

Read lsm6dso32 data via libiio

We are trying to use lsm6dso32 accelerometer/gyroscope connected to a custom hardware (non-st) via i2c. What we want to achieve is reading measured values continuously, ideally via libiio (buffered).We are building a custom linux (kernel version 5.4)...

Resolved! TDM interface with SAI for LIS25BA

Hi,I try to use a custom board with LIS25BA.I use SAI with STMF446.What I know :MCLK = 12.288 MHzWCLK = 16kHz8 slot with 3 activeso BCLK = WCLK * (8 * 16) = 2.048 MHzWhat I can do :I2C works like a charm ;)What I can't do :Configure SAI with these va...

Resolved! St is not making LIS2DH12TR what is the substitute for this mem

Resolved! Does anyone know what's the sensing technology about LIS3MDL

Resolved! IIS3DWBTR I2C address with SA0 high or low. I didn't see this in the datasheet.

in LSM6DS3TR The accelerometer is activated from power-down by ODR_XL[3:0] in CTRL1_XL (10h) the gyroscope is activated from power-down by ODR_G[3:0] in CTRL2_G (11h). For combo-mode what we have to do?

Resolved! In lsm6ds3tr value of register, CTRL9_XL (18h) for accelerometer and gyroscope operation?

LIS2DS12 3V3 alternative

Hi,I used LIS2DS12 in a previous design and i appreciated the high number of embedded function, expecially the integrated step counter; unfortunately i cannot use the same accelerometer in a new design since my power supply is 3V3: is there any equiv...

I am using an ISM330DHCX device. I want to know how I can program the device to read the 12 registers, OUTX_L_G thru OUTZ_H_A in a continuous mode.

I know that CTRL3_C, IF_INC defaults to auto-increment of register address.I am trying to stream accel/gyro register data from the device by sending a SPI read command to register OUTX_L_G. The SPI controller is configured to read 12-bytes. The regis...
