IIS2MDC always on Idle Mode

[AraceliGuerrero]

Hi!

I'm exploring the X-NUCLEO-IKS02A1 with the IIS2MDC magnetometer.

My purpose is read the output data, but I haven't even been able to read the temperature. I'm using I2C through PB8 and PB9 pins, and I have communication cuz' the sensor responds to the command "Who Am I"

After hours of trying, I thought I would read configuration registers A, B and C and I noticed that these are not being affected with my previous writing.

Even worse, register A always reads bits MD0 and MD1 to 1, which means idle mode.

 

Could the board be locked for use without libraries? The same thing happens with the rest of the sensors.

Hello @AraceliGuerrero , 

Could you please try this : 

uint8_t temp [2] = {0x2B,0x2C}; /* temperrature registers */
HAL_I2C_Mem_Read(&hi2c1, ,DevAddress, temp ,2, Buffer, 2);

Also you can check this lib :stm32-iis2mdc/iis2mdc_reg.c at main · STMicroelectronics/stm32-iis2mdc · GitHub

Hi Foued,

The temperature continues to read 0. Thanks for the lib, I'll explore it.

Hi @AraceliGuerrero , 

Could you please share with me the main.c file
