I have a project that needs to wake up roughly every 15ms, do some basic GPIO stuff, and then go back to sleep. No BLE needed. Presumably I need to be in extended sleep mode so that I can use Timer1 to wake me up (I sure don't want to be reloading from OTP/Flash every 15ms) with RAM retention.
We already have a custom board built so we can avoid the issues with trying to get power numbers and having the dev kit driver board getting in the way.
However, I don't see any Peripheral examples for extended sleep. I found the Hibernate Example (http://lpccs-docs.dialog-semiconductor.com/da145xx_tutorial_sdk6_periphe...), but that's not what I need.
I'm trying to get a program that will actually get down to the 1.2uA quoted in the datasheet for "Extended-sleep mode with 20kB RAM retained, running on RCX". However, I can't seem to find anything along those lines.
Any help would be appreciated.
