Constructing a Raspberry Pi RP2040 Low-Power Sensor Node – Day 2

Our objective this week is to design some IoT hardware that consumes a minimum of man-made energy while executing our user-generated sensor node application. Before we can accomplish the aforementioned design task, we need to understand how the Raspberry Pi Pico C/C++ SDK accesses and utilizes the RP2040 resources described in the RP2040 data sheet. The best way to pair up the Raspberry Pi Pico C/C++ SDK API calls with the associated RP2040 hardware is to write some Raspberry Pi Pico C/C++ SDK-based firmware routines and attempt to run them on some known-good RP2040 hardware. What we learn today will be used in the custom RP2040 sensor node design we will complete this week.
