This manual introduces the basic principles of low power modes using the AVR128DA48 Curiosity Nano board, and demonstrates the application of software accumulation and hardware accumulation in ADC through practical operation.
This training manual guides users through comparing power consumption between software and hardware approaches for low-power modes. It covers modifying the Curiosity Nano board for accurate power measurements and using the Event System module for efficient power management. The manual includes step-by-step instructions for configuring hardware modules and writing code in MPLAB X IDE.
The document is structured into two main assignments: comparing event system to interrupts and comparing software vs. hardware accumulation for ADC. It includes detailed hardware descriptions, modification instructions, and software implementation steps using MPLAB X and MCC plug-in.
You must cut the POWER trace and solder two pins in the holes, then connect those pins with a wire.
It provides a stabilized 2.048V reference to the ADC when enabled for the temperature sensor.
The system clock is set to 24 MHz with the internal oscillator.
