LMP90100 Sensor AFE Evaluation Board

Overview

The Texas Instruments LMP90100 Sensor AFE Evaluation Board (EVB) is a development kit for the TI LMP90xxx series of analog sensor frontends.

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 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

Zephyr RTOS includes one sample targeting the LMP90100 EVB:

Programming

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

# From the root of the zephyr repository
west build -b frdm_k64f samples/shields/lmp90100_evb/thermocouple -- -DSHIELD=lmp90100_evb
