X-NUCLEO-IKS01A1: MEMS inertial and environmental multi-sensor shield¶
This sample enables all sensors of a X-NUCLEO-IKS01A1 shield, and then periodically reads and displays data from the shield sensors:
- HTS221: Temperature and humidity
- LPS25HB: Atmospheric pressure
- LIS3MDL: 3-axis Magnetic field intensity
- LSM6DSL: 3-Axis Acceleration
This sample communicates over I2C with the X-NUCLEO-IKS01A1 shield stacked on a board with an Arduino connector. The board’s I2C must be configured for the I2C Arduino connector (both for pin muxing and device tree). 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-IKS01A1 stacked on any board with a matching Arduino connector. For this example, we use a ST Nucleo F429ZI board.
west build -b nucleo_f429zi samples/shields/x_nucleo_iks01a1
Using CMake and ninja:
cmake -B build -GNinja -DBOARD=nucleo_f429zi samples/shields/x_nucleo_iks01a1 ninja -C build
