3 Example and Power Consumption Comparison

To better understand the advantages of SleepWalking, this section provides an example using the PIC32CM6408PL10048 MCU. This microcontroller is part of the PIC32CM PL10 family, which is built on the Cortex-M0+ processor. To demonstrate the power consumption optimizations achieved by SleepWalking compared to traditional power-saving strategies, application code examples are provided for each of the three implementation strategies.

The example application monitors an ambient light sensor, collecting Analog-to-Digital Converter (ADC) samples at regular intervals and transmitting data through Universal Asynchronous Receiver/Transmitter (UART) when a brightness threshold is exceeded. This scenario represents a common pattern in battery-powered sensing applications where the system must remain responsive while minimizing power consumption.
