Hello Guys,

I am facing a little problem here in reading the who_am_I register of the LIS3DSH which is on the development board. Here are the details.

The board I'm using is STM32F40G (ver MB997D). I am using CubeMX to generate the code.

Wiring. SCL -- PA5

SDA -- PA7

Master

MasterHeader 3

I2C1_SDA (PINB7) ---------- PA7 (SDA of the sensor)

I2C1_SCL (PINB6) ---------- PA5 (SCL)

3V Pin ---------- PA6 (SEL/SDO)

LIS3DSH
