AVR®: picoPower® and Putting an Application to Sleep

 In this video:

  • Revisit AVR® Libc support for sleep.
  • Disable the brownout detector when sleeping.
  • Provide an overview of the solution project to "AVR Hands-on megaAVR® picoPower®,” which uses a very similar application to the one we have developed.
  • Explore the techniques used to save power:
    1. GPIO set as inputs with pull-ups enabled.
    2. Use the Power Reduction Register to turn off the clocks to unused peripherals.
    3. Use the Asynchronous Timer-Counter 2, which can be clocked directly from an RTC.
  • Set the sleep mode to power-save mode.
  • In the while loop if the sendflag is set, after sending the USART string, putting the AVR MCU to sleep.
