Hi
What different measure can I take to lower the power consumption on the Pi Pico RP2040?
I am running the Seeed XIAO-RP2040, use SPI and one button. All LEDS are off, power LED removed.
I have understood there are different peripherals etc on the chip that can be turned off to save power. What different things can I turn off and how do I do that?
Basically I only run a simple timer and an e-paper display. Timer based on millis() function and a button that triggers an interrupt. Some SRAM needed for the display driver.
I also have also understood that it's possible to lower the core voltage and also the system clock. Can this be done "safely", i.e. without compromising functionality, and how does lowering the system clock affect the millis() function?
