picoPower® Technology and Putting an Application to Sleep

AVR® Microcontroller (MCU): picoPower® Technology and Putting an Application to Sleep
Overview
In this video:
Revisit AVR® Libc support for sleep.
Disable the Brown-out detector when sleeping.
Provide an overview of the solution project to AVR hands-on megaAVR® device picoPower technology, which uses a very similar application to the one we have developed.
Explore the techniques used to save power:
General Purpose Input/Output (GPIO) set as inputs with pull-ups enabled.
Use the Power Reduction register to turn off the clocks to unused peripherals.
Use the Asynchronous Timer-Counter 2 which can be clocked directly from a Real Time Clock (RTC).
Set the Sleep mode to Power-Save mode.
In the while loop, if the send flag is set after sending the Universal Synchronous Asynchronous Receiver Transmitter (USART) string, it puts the AVR MCU to sleep.
If you need to work with Microchip Support staff directly, you can submit a technical support case. Keep in mind that many questions can be answered through our self-help resources, so this may not be your speediest option.
