I am interfacing this lsm9ds1 MEMS sensor with the STM32F429zit6 nucleo board. LSM9DS1 IS NOT Responding I am using ST lsm9ds1 drivers on github using data polling code sensor is not responding, anyone tell me where the problem occures?

Hi @PRAMU.1​ ,

are you using SPI or I2C interface for the communication?

And are you able to read the chip ID (0Fh register)?

It would be helpful if you could share also the scope of the digital pattern working on your application.

it returns always 0x00 only

[PRAMU.11]

im using i2c interface

[PRAMU.11]

continuesly looping never get out of the loop.

Hi @PRAMU.1​ ,

but are you able to receive a correct acknowledge signal from the I2C communication?

Can you share the scope digital pattern of the communication?

how can i configure platform write and read in application code whre we are included that functions.

[PRAMU.11]

im not mention platform write and read in main.c is this mention or not?

[PRAMU.11]

/** Please note that is MANDATORY: return 0 -> no Error.**/

int32_t platform_write(void *handle, uint8_t Reg, uint8_t *Bufp, uint16_t len)

int32_t platform_read(void *handle, uint8_t Reg, uint8_t *Bufp, uint16_t len)

where can i write these functions

Hi @PRAMU.1​ ,

In order to integrate the, you can refer to the dedicated section in the readme file of Github homepage, at the paragraph:

Did you already try this procedure?

Hello Mr Borlini, if I use custom board of STM32L083, can I use these LSM9DS1 .c & .h file driver?

Hi Anuar @ABin .1​ ,

yes you can, you have just to take care of the specific platform in terms of the pin configuration and the proper peripheral (e.g SPI) initialization.

However, next time please create a new post for a new question ;)
