The Atmel Samb11 marketing and user guides discuss the many benefits of ULP and the ability to automatically drop into ULP mode whenever there is no application task work to do, while readily awaking via interrupt from AOGPIO0-2 or AOTimer. It's all very powerful if one could get it to work as advertised...
Unfortunately, the AOTIMER example does not work, and there is no example showing how to configure the AO GPIO pins to wake up the MCU.
Worse yet, all of this is supposed to work well at the same time as BLE is operating as needed at a high priority during waking periods.
While conceptually compelling and valuable, the lack of working examples makes it difficult to impossible to get this all working. And how can it be the Explained Pro with debugger doesn't function correctly with ULP?
Does anyone have a functional example where AON properly wakes up the MCU from ULP mode, interrupting and triggering callbacks as needed?
Thanks in advance.
