- 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
- master:
- 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.
