Discussion - EVE / Re: BT815 - Wake-Up via interrupt
« on: January 12, 2024, 04:24:03 PM »
Hi,
Do I understand the datasheet of the BT815 correctly: When the bt815 has only power, but is never activated (PD_N is never pulled HIGH), then the INT_N pin follows the interrupt of the capacitive screen?
Or do I have to set BT815 to active state, do some settings and when I go back to powerdown state, then I get this behaviour?
The datasheet says in 4.8.8.:
EDIT:
I got it running and it is just like the docs says.
In case you work with a esp32 -> Keep in mind that you need to configure the RTC-pin for the wakeup from deep-sleep right before the deep-sleep command.

For capacitive touch, the INT_N pin will follow CTP_INT_N pin when the BT815 is in STANDBY, SLEEP or
POWERDOWN state.
