Low Power ADC User Guide

Getting started

The Low Power ADC project is designed to work with the Tower System or in a stand alone setting.1) Set your target board in a place where temperature is constant. 2) Download the program to a target board. 3) Wait until the green LED light turns on. 4) Increment or decrement temperature to see the changes.

Caution

The use of liquids and some gases can cause a short circuit. Placing the board in contact with very hot or cold materials can damage it. Do not touch the microcontroller or any other part of the board with your tongue.

Overview

The Low Power ADC project is a simple demonstration program that uses the KSDK software. The microcontroller is set to a very low power stop (VLPS) mode, and every 500 ms an interrupt wakes up the ADC module and takes the current temperature of the microcontroller. While the temperature remains between boundaries, both LEDs are off. If the temperature is higher than average, a red LED comes on. If it is lower, a blue LED comes on. The intent of this program is to provide a simply example of how ADC works during a VLPS mode and to provide a simple debugging, "golden", project.

Supported platforms

Currently, the Low Power ADC project is supported on these platforms:
  • TWR-K64F120M
  • FRDM-K64F120M
