move various esp32 pins to avoid strapping pins #6

Closed jdbaptista closed 2 months ago

jdbaptista commented 2 months ago

Made to solve issue #5.

Changes:

Moved interrupt lines to esp32 input only GPIO pins, including SENSOR_VN (which can be used as an input only GPIO pin).
Moved LED pins slightly to remove the use of esp32 strapping pins as much as possible.

It is possible to make use of the last input only GPIO pin by moving T_SW to SENSOR_VP, which could free up the last strapping pin, however this would put T_SW physically away from where it should be. It may be something to keep in mind for the future though.

Looks good to me. Made some small changes but should be good to merge.
