Component: LIS2DH12

  • This component will show you how to use I2C module read external i2c sensor data, here we use LIS2DH12, which is a 3-axis accelerometer.
  • Pin assignment:
    • master:
      • GPIO18 is assigned as the data signal of i2c master port
      • GPIO19 is assigned as the clock signal of i2c master port
  • Connection:
    • connect sda of sensor with GPIO18
    • connect scl of sensor with GPIO19
    • no need to add external pull-up resistors, driver will enable internal pull-up resistors.
