X-NUCLEO-IKS01A2: shield Standard (Mode 1) sample
This sample enables all sensors of a X-NUCLEO-IKS01A2 shield, and then periodically reads and displays data from the shield sensors:
HTS221: Ambient temperature and relative humidity
LPS22HB: Atmospheric pressure and ambient temperature
LSM6DSL: 3-Axis Acceleration and 3-Axis Angular Velocity
LSM303AGR 3-Axis Acceleration and 3-axis Magnetic field intensity
This sample communicates over I2C with the X-NUCLEO-IKS01A2 shield stacked on a board with an Arduino connector. The board’s I2C must be configured for the I2C Arduino connector in the devicetree. See for example the ST Nucleo F401RE board source code:
Please note that this sample can’t be used with boards already supporting one of the sensors available on the shield (such as disco_l475_iot1) as zephyr does not yet support sensors multiple instances.
Building and Running
This sample runs with X-NUCLEO-IKS01A2 stacked on any board with a matching Arduino connector. For this example, we use a ST Nucleo F401RE board.
