Evaluating the MAX31827 #

The MAX31827 evaluation kit (EV kit) demonstrates the MAX31827 I2C temperature switch and sensor with hardware-selectable address and alarm. The MAX31827 EV kit comes with the 6-pin WLP MAX31827ANTABRPF+ installed.

Hardware Specifications #

Power Supply Requirments #

For this specific project, the MAX31827EVKIT is powered by the 3V3 supply from the MAX32666FTHR.

Board Connector and Jumper Settings #

Pin Description

Please see the following table for the pin assignments:

Name

Description

VDD

Connect to 3V3 supply

GND

No-OS Build Setup #

Please see: https://wiki.analog.com/resources/no-os/build

No-OS Supported Examples #

The initialization data used in the examples is taken out from: Project Common Data Path

The macros used in Common Data are defined in platform specific files found in: Project Platform Configuration Path

Basic example #

This is a simple example that initializes the MAX31827 and reads input temperature periodically.

In order to build the basic example make sure you have the following configuration in the Makefile

# Select the example you want to enable by choosing y for enabling and n for disabling
BASIC_EXAMPLE = y
IIO_EXAMPLE = n

IIO example #

This project is actually a IIOD demo for MAX31827EVKIT. The project launches a IIOD server on the board so that the user may connect to it via an IIO client.

Using IIO-Oscilloscope, the user can configure the device.

If you are not familiar with ADI IIO Application, please take a look at: IIO No-OS

If you are not familiar with ADI IIO-Oscilloscope Client, please take a look at: IIO Oscilloscope

The No-OS IIO Application together with the No-OS IIO MAX31827 driver take care of all the back-end logic needed to setup the IIO server.

This example initializes the IIO device and calls the IIO app as shown in: IIO Example

In order to build the IIO project make sure you have the following configuration in the Makefile

# Select the example you want to enable by choosing y for enabling and n for disabling
BASIC_EXAMPLE = n
IIO__EXAMPLE = y
