TPL5110 - Wake pin #2

Closed ricaun closed 6 years ago

I realy like the ideia to use TPL5110 to manager a wakeup timer.

But I don't understand why you put the DRVN of TPL5110 on A2 pin...

Maybe change to pin D3 how haves external interrupt, this way is possible to put the arduino on SLEEP_FOREVER and TPL5110 will wakeup. And put the button to D4.

this is because D3 is already used by the push button and needed to keep compatibility with old boards. Anyway it's not a problem I'm using sleep forever waked by pin change interrupt on A2 it's working fine

Nice!! I didn't know that pin change interrupts can wake up the arduino, That's awesome, I need to try some codes.
