Requirements

---

This shield can only be used with a development board that provides a configuration for Arduino connectors and defines a node alias for the SPI interface (see :ref:shields for more details).

The SPIO connector pins on the LMP90100 EVB can be connected to the Arduino headers of the development board using jumper wires.

For more information about interfacing the LMP90xxx series and the LMP90100 EVB in particular, see these TI documents:

• LMP90100 Sensor AFE Evaluation Board User's Guide_
• LMP90100 Multi-Channel, Low Power 24-Bit Sensor AFE_

Samples

Programming

---

Set --shield lmp90100_evb when you invoke west build. For example:

.. zephyr-app-commands:: :zephyr-app: samples/shields/lmp90100_evb/rtd :board: frdm_k64f :shield: lmp90100_evb :goals: build
