Any time I ask a really specific question here it always seems to go by the wayside. But what the heck -- it's Friday, it's late, and my @#$% processor won't go to sleep!!!
Anyone have any mileage with the ST Arm Cortex parts and sleep mode? I've got a STM32F303 that doesn't really need it that goes to sleep beautifully, and I've got an STM32F051 in an application where low power is critical that isn't going to sleep at all!!!
I'm calling the "wfe" instruction, I've tried calling the "wfi" instruction instead, and got no difference. I've dug through the manuals for the past two hours looking for that magic "oh, by the way, you need to setorclear this magic bit", all to no avail.
So, any help is appreciated. Even wild-ass suggestions, as long as they come from the ARM Cortex world.
