I am layout out a schematic for a design that will use a Photon along with a CAP1188 Capacitive Touch chip.
This is a battery based design so the Photon will be put to sleep and I want to be able to wake the Photon using the Alert pin on the CAP1188 chip.
Which of these Alert modes would be best for working with a sleeping Photon?
Adafruit’s CAP1188 breakout has the ALERT pin wired to 3.3v with a pull-up resistor.
Here is the datasheet for the CAP1188 chip if needed: http://ww1.microchip.com/downloads/en/DeviceDoc/00001620C.pdf
