lsm303 stm32F407G

[Chris_student]

I have some following up questions after my last post: https://community.st.com/t5/stm32-mcus-products/lsm303dlhc-c/m-p/597950#M224881. I now have a code that does not give any errors. with the librarys in the picture below. But when i run the code and call for: BSP_accelero_init(); it returns a 1, this means that the sensor is not found. according to the library the I2C adresses are 32 and 3C, but when i do a I2C scanner on my arduino it says this should be 18 and 1E. After trying those adresses it still does not work. Could enyone help me with this?

Hello @Chris_student , 

The I2C addresses (0x32 and 0x3C) are correct. (from datasheet 5.1.1 section https://www.st.com/resource/en/datasheet/lsm303dlhc.pdf )

You can connect an oscilloscope and check SDA and SCL behavior.

I found out my school gave us chinees fake of the sensor. So we are not using it anymore. But thanks for your help!
