1 Introduction

Application Note

In this demonstration we will show you how to extend the battery life of our

application by multiple factors by modifying only the firmware. You will see that

while some of the modifications are very simple and only require setting some

registers, other modifications will need some rewriting of the code.

We will use a capacitor as a battery in this demonstration because it is easy to

recharge with the same amount of energy. We will use the discharge time as a

measure of power consumption.

Our demonstration application will do one ADC measurement, perform 1000 cycles

worth of processing, and send the string “More oomph to your amps, picoPower!”

and the iterations count on the UART. This will be repeated each second. Before

reading this application note, you should download the datasheet for the

ATmega88PA from
