    I would like to use timeouts on the Mini Ultra (8bit) ATmega4808 that are less than 1 second. For example, 600 ms. I want to do this using the RocketScream_LowPowerAVRZero.h and RocketScream_RTCAVRZero.h for RTC standby sleep, and perhaps using deep sleep with the PIC.

    No documentation or example convinces me that this is possible. But I find it hard to believe that it cannot be done.

    Can anyone enlighten me?

    I have written the library with the smallest time base as 1 s as I believe that is what being used in most low power application (sleep->wake->sleep behaviour). But, if you want to go anything smaller than that, you will need to play with the pre-scaler somewhere along line #61 of the source code. The main reason I didn’t provide a smaller base time is, the maximum period it could support is too small rendering it useless for majority of the low power application (again like the above example).

    Thanks for the information!
    I need to report a simple sensor (I2C) reading on 1 s interval boundaries. The data analysis people go nuts if they can’t have a a pretty exact 1 s cadence to work with across large numbers of samples.
